* fix: auto-detect audio sample rate for device compatibility (#262)
- Add _get_supported_sample_rate() helper function
- Tests device default rate first, then common rates (48k, 44.1k, 32k, 22k, 16k, 8k)
- Fixes 'Invalid sample rate' error for devices like Vocaster One (48kHz only)
- Update test_audio_input(), _record_audio(), and _attempt_audio_reconnection()
- Return detected sample_rate in test_audio_input() result dict
* fix: import pyaudio inside _get_supported_sample_rate
* fix: resample audio to 16kHz for Vosk/Whisper compatibility
- Store detected sample rate in self._capture_sample_rate
- Resample audio chunks to 16kHz before appending to buffer (linear interpolation)
- Initialize _capture_sample_rate to 16000 in __init__
- Update both _record_audio() and _attempt_audio_reconnection()
This ensures devices like Vocaster One (48kHz only) can capture audio
and speech recognition engines (Vosk/Whisper) receive 16kHz as expected.
* style: fix black formatting
* feat(ui): show sample rate info in audio test results
- Display detected sample rate in test results (e.g., '48kHz → 16kHz auto')
- Remove redundant numpy import in _record_audio function
- Helps users understand that non-16kHz devices are supported
* chore(release): prepare v0.7.0-beta

* docs: update version history in RELEASE_PROCESS.md
Add entries for 0.6.0-beta through 0.7.0-beta to the version history table.
* feat: detect incompatible Intel GPUs and fallback to CPU
Implements two-layer protection for users with older Intel GPUs that lack
VK_KHR_16bit_storage support required by whisper.cpp Vulkan backend.
Affected GPUs: Intel Gen7 and older (Ivy Bridge, Haswell, Sandy Bridge)
- Intel HD Graphics 2500/4000 (Ivy Bridge)
- Intel HD Graphics 4400/4600 (Haswell)
Layer 1: Install-Time Detection (Prevention)
- New check_vulkan_gpu_compatibility() function in install.sh
- Parses GPU name from vulkaninfo output
- Checks against known incompatible patterns
- Shows clear warning and recommends CPU backend
- Updates detect_whispercpp_backends() to skip Vulkan for incompatible GPUs
Layer 2: Runtime Fallback (Safety Net)
- Added error handling in recognition_manager.py _init_whispercpp()
- Catches RuntimeError with "16-bit storage" or "Unsupported device"
- Automatically disables Vulkan/CUDA and retries with CPU
- Shows desktop notification explaining the fallback
Fixes#238
* fix(gpu): improve compatibility detection and add tests
When an input device is disconnected, select() reports the fd as
readable but read() fails with ENODEV. Previously, the code caught
the error but kept the dead fd in the list, causing an infinite
busy loop that consumed 100% CPU.
Now disconnected devices are removed from both self.devices and
self.device_fds when read() fails, preventing the busy loop.

On desktop environments like KDE Plasma, the IBus daemon is not started
by default. Previously, Vocalinux would attempt to register its IBus
engine anyway, which would fail and (before #240) not properly fall back
to alternatives.
This change:
- Adds is_ibus_daemon_running() to check if ibus-daemon is running
- Skips IBus setup entirely when daemon isn't running
- Logs an informative message explaining why IBus is skipped
- Falls back to ydotool/xdotool immediately (no wasted time)

* refactor(ui): convert settings dialog to tabbed layout
Convert the settings dialog from a long scrolling list to a tab-based UI
using Gtk.Notebook. This follows GNOME HIG best practices for settings
panels with 3-5 sections.
Changes:
- Add notebook CSS styling for modern tab appearance
- Create 4 tab content boxes (Recognition, Audio, Shortcuts, General)
- Replace ScrolledWindow with Gtk.Notebook
- Reorganize settings sections into appropriate tabs:
- Recognition: Engine, Model, Language, VAD, Silence, Test
- Audio: Device selection, Audio level test
- Shortcuts: Keyboard shortcuts
- General: Autostart, Start minimized
- Widen dialog to 700px to accommodate tab content
This eliminates vertical scrolling and provides a cleaner UX with
logical grouping of related settings.
* refactor(settings): split recognition tab into Speech Engine and Recognition tabs
- Reordered tabs by importance: Speech Engine, Recognition, Audio, Shortcuts, General
- Split the Recognition tab into two separate tabs:
- Speech Engine tab: Engine, Model Size, Language, Model Info
- Recognition tab: VAD Sensitivity, Silence Timeout, Test Recognition, Recognition Status
- This reduces vertical height of each tab and improves usability
* fix(ui): reduce settings dialog height to 50% of screen
Previously set to 75% which made the dialog unnecessarily tall.
* fix(ui): remove redundant close button from settings dialog
Settings auto-apply, so the bottom close button is unnecessary.
Users can close using the title bar X button.
* test(settings): update test for no-action-buttons pattern
The settings dialog now uses title bar close instead of a bottom
Close button, so update the test accordingly.
* fix: prevent multiple instances from running simultaneously
Add single-instance enforcement using file locking to prevent duplicate
instances when auto-start is enabled on boot (issue #244).
Changes:
- Add single_instance.py module with fcntl-based file locking
- Check for existing instance early in main() before any initialization
- Register atexit handler to release lock on normal exit
- Lock file located at ~/.local/share/vocalinux/instance.lock
If another instance is already running, the app exits gracefully with
a helpful error message telling the user how to resolve the situation.
* fix: add GTK notification when duplicate instance detected
Show a system notification to the user when another instance is already
running, in addition to the existing stderr/log output.
Changes:
- Import Notify from gi.repository when duplicate instance detected
- Show notification with error icon and message
- Give notification time to display before exiting (0.5s sleep)
- Fallback to silent exit if notification fails (e.g., headless)
* feat(ui): add auto-start on boot support
- Add --start-minimized CLI flag for autostart entry
- Create autostart_manager.py to handle XDG autostart desktop entry
- Add autostart config option in config_manager.py
- Add Start on Login toggle in Settings dialog
- Add Start Minimized toggle in Settings dialog
- Add Start on Login checkbox in system tray menu
- Add first-run dialog to ask about autostart preference
Closes#184
* fix(test): add first_run: False to mock config settings
The tests were failing with StopIteration because main() now checks
for first_run and shows a dialog if True. By setting first_run: False
in the mock config, we skip the first-run dialog code path.
* fix(ui): harden autostart behavior across Linux sessions
Use XDG-compliant autostart paths and robust Exec command resolution, keep first-run prompt semantics correct, and fix GTK toggle handling so state changes are applied reliably.
* docs(autostart): document XDG startup model and limits
Clarify that Vocalinux uses desktop-session XDG autostart, not systemd services, and explain compatibility expectations for mainstream DEs versus minimal/custom WM sessions.
* feat(ui): add first-run quick-start guidance text
Expand the welcome dialog with concise first-time usage guidance and clear direction to the tray menu Settings entry while preserving the existing autostart decision flow.
* fix(uninstall): remove XDG autostart desktop entry
Ensure uninstall removes ~/.config autostart registration and reports leftover autostart entries during verification.
* fix(install): ignore defunct processes in running-check
Filter installer process detection to exclude defunct entries and installer/uninstaller shells so stale zombie rows do not block reinstall.
* fix(uninstall): ignore defunct processes in running-check
Use filtered process detection so zombie entries and installer shells do not trigger false running-process warnings during uninstall.
* fix(ibus): raise exception on setup failure to enable fallback
- Add IBusSetupError exception class for detailed error context
- Modify _setup_engine() to raise exception instead of silent return
- Ensures text_injector.py fallback mechanism works when IBus fails
- Add unit tests for IBusSetupError and setup failure scenarios
Fixes silent IBus text injection failures on Wayland/Fedora reported in #34

* test(text-injector): add tests for IBus setup failure fallback
- Test that TextInjector falls back to xdotool when IBus fails
- Test fallback on both X11 and Wayland environments
- Test that text injection still works after IBus failure

* chore(release): prepare v0.6.3-beta
- Fix#220: Installer default tag now points to correct version
- Update version from 0.6.2-beta to 0.6.3-beta
- Update documentation version references
- Update website schema and badges
- Add v0.6.3-beta changelog entry
The v0.6.2-beta installer was defaulting to v0.6.1-beta which is
missing the psutil dependency, causing fresh installs to fail.
* docs(update): simplify update guide, remove duplicate version history
The command processor was adding a leading space when processing action
commands with text after them (e.g., 'delete that text' -> ' text').
This was causing the first speech to always have an unwanted leading space.
Changes:
- Modified command_processor.py to only add space when there's text BEFORE
the action command, not at the beginning of the transcription
- Updated test cases to reflect the correct behavior without leading spaces
Fixes leading space issue on first speech.
The previous fix used `suppress_non_speech_tokens` which doesn't exist
in pywhispercpp's C++ bindings (whisper.cpp uses `suppress_nst` but it's
not exposed). This caused initialization error:
"_pywhispercpp.whisper_full_params object has no attribute suppress_non_speech_tokens"
Changes:
- Remove invalid `suppress_non_speech_tokens` parameter
- Add `no_speech_thold=0.6` and `entropy_thold=2.4` for better filtering
- Add `_filter_non_speech()` post-processing function that filters:
- [BLANK_AUDIO] and other bracketed tokens
- Music notes (♪♫♬♩♭♮♯)
- Pure punctuation sequences
- Low speech-content text (<30% alphanumeric)
Fixes#219
IBus sends Unicode directly via commit_text(), bypassing keyboard layout
issues entirely. This provides the same reliable text injection on X11
that we already have on Wayland.
Changes:
- Add X11_IBUS desktop environment enum
- Prefer IBus on both X11 and Wayland (before falling back to xdotool)
- Add tests for X11 IBus preference and fallback behavior
This supersedes the layout-switching approach in PR #206, which only
worked on X11 and had overhead from layout switching.
Closes#199
Fixes#215
The crash (segfault at ffffffff in libstdc++.so.6) was caused by a race
condition between the transcription thread and model reconfiguration:
1. When recording finishes, `_transcribe_with_whispercpp()` accesses
`self.model.transcribe()` which is a C++ object via pywhispercpp
2. If settings change simultaneously, `reconfigure()` sets `self.model = None`
3. The transcription thread then accesses null/freed memory → segfault
This fix adds a `_model_lock` to protect concurrent access to:
- `self.model` (Whisper and whisper.cpp engines)
- `self.recognizer` (VOSK engine)
The lock is now used in:
- `_transcribe_with_whisper()` - protects model.transcribe()
- `_transcribe_with_whispercpp()` - protects model.transcribe()
- `_process_final_buffer()` - protects recognizer for VOSK
- `reconfigure()` - protects model reinitialization
Each transcription method also checks if model/recognizer is None before
proceeding, returning an empty result gracefully if reconfiguration is in
progress.
* feat(text-injection): add IBus engine for Wayland text injection
Add a custom IBus input method engine for reliable text injection on
Wayland, solving keyboard layout issues with xdotool/wtype.
Key features:
- IBus proxy engine that passes through normal keyboard input
- Text injection via Unix socket IPC
- User-level component installation (no sudo required)
- Auto-reactivation when user switches keyboard layouts
- Graceful fallback when IBus is unavailable
Changes:
- New ibus_engine.py with VocalinuxEngine and IBusTextInjector
- TextInjector now prefers IBus on Wayland for best compatibility
- Add IBus GObject bindings to system dependencies in install.sh
- Add comprehensive tests for IBus engine

* security: secure IBus socket with permissions and peer verification
- Set directory to 0o700 (owner-only access)
- Set socket to 0o600 (owner-only read/write)
- Add SO_PEERCRED verification to reject connections from other users
This provides defense-in-depth: even if directory permissions are
bypassed, the socket server verifies the connecting process UID.

- Never push directly to main
- All changes require a PR
- Wait for CI before merging
- Squash merge PRs
- Add suppress_blank=True and suppress_non_speech_tokens=True parameters
to whisper.cpp Model initialization to prevent blank audio tokens
from being output when transcribing silent audio
- This implements Option 2 from the investigation: suppress at the
whisper.cpp level rather than post-processing filtering
- Root cause: whisper.cpp outputs a special [BLANK_AUDIO] token
when transcribing silent audio, which was being inserted into the
text field when users paused with the mic on
The _attempt_audio_reconnection method was incorrectly accessing
paInt16 as an attribute of the PyAudio instance instead of the
pyaudio module. Added local import and fixed the reference.

When transcribing text continuously (stop and start again), the new
text was being injected immediately after the last character without a
space. This caused issues like "Hello world.This is a test" instead of
"Hello world. This is a test".
Fix:
- Check if the last injected text ends with punctuation or other characters
that typically need a space after them (., ,, !, ?, ;, :, quotes, etc.)
- If yes, add a space before injecting the new text
- Log when space is added for debugging
Characters requiring space:
- Punctuation: . , ! ? ; : ) ] } - _
- Quotes: " '
Closes#151
When stopping voice recognition, the stop sound was being captured by the
microphone and transcribed as "thank you" or similar text. This happened
because the sound was played BEFORE stopping recording.
Fix:
- Stop recording FIRST by setting should_record = False
- Wait briefly for audio thread to stop
- Discard the last ~1 second of audio buffer (15 chunks) which would
contain the feedback sound
- THEN play the stop sound after recording has stopped
- Process remaining valid audio
This ensures that audio captured during the stop sound is discarded and
won't be transcribed.
Technical details:
- Audio recorded in 1024-sample chunks at 16000 Hz = ~64ms per chunk
- Discarding 15 chunks = ~960ms of audio
- Uses existing _buffer_lock for thread safety
Closes#150
Removes the _escape_text method and its usage since text is passed to
subprocess.run() via list arguments, not shell strings. When using
subprocess with a list (without shell=True), arguments are passed directly
to the command without shell interpretation, making shell escaping
unnecessary and actually harmful.
This fixes the bug where apostrophes and other special characters were
typed with backslash escapes (e.g., "Let\'s" instead of "Let's").
Changes:
- Remove _escape_text() method from TextInjector class
- Remove escaped_text variable from inject_text() method
- Pass text directly to _inject_with_xdotool() and _inject_with_wayland_tool()
- Update docstrings to remove references to escaped text
- Update tests to verify text is NOT escaped when passed to subprocess
Closes#119
Add _prevent_scroll_on_hover() helper function that blocks scroll events
on ComboBoxes and SpinButtons unless they have explicit focus. This fixes
the UX issue where scrolling through the settings dialog accidentally
changes dropdown/spinbutton values when the mouse cursor happens to be
over them.
Changes apply to:
- Audio device combo
- Engine selection combo
- Model size combo
- Language selection combo
- VAD sensitivity spin button
- Silence timeout spin button
- Keyboard shortcut combo
Users must now click/focus a widget first before scroll events will
modify its value, making scrolling through settings much more predictable.
* feat(shortcuts): add customizable keyboard shortcuts via GUI
Implement configurable keyboard shortcuts for toggling voice recognition,
allowing users to choose between Ctrl+Ctrl, Alt+Alt, Shift+Shift, or
Super+Super (Windows key) double-tap shortcuts.
Changes:
- Add shortcuts configuration section to settings dialog with dropdown
- Update keyboard backends (pynput and evdev) to support configurable
modifier keys for double-tap detection
- Add SUPPORTED_SHORTCUTS, SHORTCUT_DISPLAY_NAMES constants in base module
- Update KeyboardShortcutManager to accept and pass shortcut configuration
- TrayIndicator now reads shortcut from config on startup
- Add comprehensive tests for shortcut configuration and parsing
The default shortcut remains Ctrl+Ctrl for backward compatibility.
Changes take effect after app restart (noted in UI).
Closes#16
* feat(shortcuts): enable live shortcut switching without app restart
Add restart_with_shortcut() method to KeyboardShortcutManager that stops
the listener, updates the shortcut configuration, and restarts with the
new shortcut. The settings dialog now applies shortcut changes immediately
with visual feedback indicating success.
- Add restart_with_shortcut() to KeyboardShortcutManager
- Add update_shortcut() to TrayIndicator for exposing live updates
- Update SettingsDialog to use callback for immediate shortcut changes
- Show green success message when live switching succeeds
- Add 7 new tests for restart_with_shortcut functionality
* fix: use Python 3.8 compatible context manager syntax
Convert parenthesized context manager (Python 3.10+) to nested with
statements for Python 3.8 compatibility in test_keyboard_shortcuts.py
* feat(ui): redesign settings dialog with modern GNOME HIG styling
Completely redesign the settings dialog to follow GNOME Human Interface
Guidelines with a modern, card-based preference page layout:
UI/UX Improvements:
- Add PreferencesGroup and PreferenceRow custom widgets mimicking
libadwaita's AdwPreferencesPage pattern
- Implement proper visual hierarchy with card-style grouped sections
- Add comprehensive CSS stylesheet with theme-aware colors
- Use proper spacing, border-radius, and typography following HIG
- Add smooth reveal animations for settings applied notifications
- Improve status indicators with semantic colors (success/warning/error)
Technical Changes:
- Replace flat grid layout with scrollable content area
- Use ListBox rows for better accessibility and keyboard navigation
- Add proper Gdk version requirement to prevent version conflicts
- Consolidate model info display into a unified info card
- Improve code organization with dedicated section builder methods
Visual Features:
- Card-like preference groups with subtle borders and shadows
- Proper row hover states for interactive feedback
- Status color coding: green for success, yellow for warnings, red for errors
- Cleaner legend display for model download status
- Modern flat button styling for auxiliary actions
All 328 existing tests continue to pass.
* refactor(settings): simplify to Close-only button pattern
Remove Apply/Cancel buttons in favor of pure instant-apply UX:
- Settings now apply immediately when changed (auto-apply)
- Single Close button follows modern GNOME Settings pattern
- Remove redundant _revert_settings() and _show_settings_applied_message()
- Update docstring to reflect instant-apply design
This resolves the UX inconsistency where settings auto-applied
but also had Apply/Cancel buttons that were confusing.
* feat(ui): redesign Logs and About dialogs with GNOME HIG styling
Logs Dialog:
- Modern card-based filter bar with grouped controls
- Theme-aware log level colors (works in light/dark mode)
- Toolbar with icon buttons for Copy, Export, Clear actions
- Toast notifications for user feedback
- Close-only button pattern (consistent with settings)
About Dialog:
- Extract to separate about_dialog.py module
- Use standard Gtk.AboutDialog (GNOME recommended)
- Clean credits section with contributors and tech stack
- Remove emojis for cleaner professional look
- Better organized credit sections
Both dialogs now follow the same design language as the
Settings dialog redesign.
* fix(keyboard): verify Ctrl key capability in evdev backend availability check
The evdev backend's is_available() method was incorrectly returning True
when keyboard devices were found, even if the user lacked permission to
access them or if the accessible devices didn't have Ctrl key capability.
This caused keyboard shortcuts to fail silently on Wayland when the user
wasn't in the 'input' group, as the backend was selected but couldn't
actually monitor keyboard events.
Changes:
- Add device_has_ctrl_key() helper to verify a device supports Ctrl keys
- Update is_available() to check both device accessibility AND Ctrl key
capability
- Now correctly returns False when no usable keyboard device is found,
triggering proper error messages about permissions
This ensures users get clear feedback about missing permissions instead
of silently non-working keyboard shortcuts.
* fix(install): use sg command to apply input group without logout
The install.sh script adds the user to the 'input' group for keyboard
shortcuts on Wayland, but this change doesn't take effect until logout.
Updated wrapper scripts to use 'sg input -c ...' to run vocalinux with
the input group applied, even if the user hasn't logged out yet. This
provides a much better user experience as keyboard shortcuts work
immediately after installation.
The wrapper detects if:
1. User is in /etc/group for 'input' group
2. Current session doesn't have the group active
If both conditions are true, it uses 'sg' to apply the group.
* Fix Python 3.13 and Wayland compatibility
This commit addresses installation failures on modern Linux distributions
(Ubuntu 25.10+) with Python 3.13 and Wayland-only sessions.
Changes:
1. **Add Python 3.13 support** (pyproject.toml)
- Add Python 3.13 to classifiers
- Update black target versions to include py312, py313
- No code changes needed - already compatible
2. **Use system site-packages for PyGObject** (install.sh)
- Change venv creation to use --system-site-packages flag
- Avoids PyGObject build failures with Python 3.13
- System PyGObject (python3-gi) is already installed as dependency
- Building from source is unnecessary and fragile with new Python versions
3. **Improve Wayland text injection support** (install.sh)
- Install ydotool as fallback (wtype doesn't work with GNOME Wayland)
- Add user to 'input' group for uinput device access
- Install udev rule for /dev/uinput permissions
- Provide clear warning about logout requirement
Technical details:
- wtype uses Wayland virtual keyboard protocol (not supported by GNOME)
- ydotool uses Linux uinput kernel module (works with all compositors)
- System PyGObject 3.50.0+ supports Python 3.13
- Building PyGObject 3.54.5 from source fails with Python 3.13 build tools
Fixes installation on:
- Ubuntu 25.10 (Questing Quokka) - Wayland-only, Python 3.13
- Arch Linux with Python 3.13
- Fedora 41+ with Python 3.13
Tested on: Ubuntu 25.10 with Python 3.13.7, GNOME 49 Wayland
Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
* Prioritize ydotool over wtype for universal Wayland compatibility
wtype uses the virtual-keyboard Wayland protocol which is not supported
by GNOME/Mutter compositors. ydotool uses the Linux uinput kernel module
which works with all Wayland compositors including GNOME.
This change swaps the priority order to check ydotool first, ensuring
text injection works on GNOME Wayland (Ubuntu 25.10+) while still
falling back to wtype for compositors that support it.
Tested on Ubuntu 25.10 with GNOME 49 Wayland - text injection now works
perfectly with ydotool.

- Added edge case tests for text injection on X11/Wayland
- Added keyboard shortcut injection tests
- Added error handling and callback tests
- Added configuration management tests
* fix: Use runtime CI mode detection to fix Python 3.8/3.10 tests
Change CI_MODE from module-level constant to _is_ci_mode() function
that is evaluated at runtime. This ensures pytest detection works
correctly on all Python versions, since pytest modules may not be
loaded at import time.
* fix: Add PYTEST_RUNNING env var for reliable pytest detection in CI
The previous approach to detect pytest at runtime wasn't working
reliably on Python 3.8/3.10 in CI environments. This adds a
PYTEST_RUNNING=1 environment variable set early in conftest.py
that _is_ci_mode() can check to reliably determine if tests are
running.
* fix: Use patch.object for reliable mocking in audio_feedback tests
The previous approach using patch() with module paths didn't work
reliably because the module reimport caused the patched objects
to not be the same as the ones the functions referenced.
Using patch.object() on the imported module's attributes ensures
the patches are applied to the actual objects the functions use.
* fix: Use patch.object for reliable mocking in test_settings_callback
The test was failing on Python 3.8/3.10 because the module-level patch
for SettingsDialog wasn't being applied reliably across all Python
versions due to import timing differences.
Using patch.object() on the imported module ensures the mock is applied
to the actual reference that _on_settings_clicked() uses, regardless of
Python version or module caching behavior.
* fix: Debian dependencies in install.sh
Fixes issue #102: Building on a fresh Debian installation in a VM with GNOME
required additional dependencies for pip to install. pip fails with Meson submodule
failing without cairo and girepository-2.0 development packages.
Changes:
- install.sh: Separated Debian packages from Ubuntu packages; selects Debian if found;
otherwise same workflow for apt packages
- docs/INSTALL.md: Separated Debian installation instructions from Ubuntu, updated package list.
- src/vocalinux/main.py: Fixed comment indicating gir1.2-ayatana-appindicator3 is only for Debian
13- it's for Debian 11+
- CONTRIBUTING.md: Separated Debian installation instructions from Ubuntu, updated package list.
* fix: fall back to Ayatana AppIndicator

* feat: add Wayland support for keyboard shortcuts using evdev backend
This commit adds multi-backend support for keyboard shortcuts, enabling
them to work on Wayland sessions where pynput does not work.
**Changes:**
- New `keyboard_backends/` package with modular backend system
- `base.py`: Abstract base class for keyboard backends
- `pynput_backend.py`: Existing pynput implementation (X11/XWayland)
- `evdev_backend.py`: New evdev implementation (X11 & Wayland)
- `__init__.py`: Backend factory with auto-detection
- Updated `keyboard_shortcuts.py`:
- Refactored to use backend system
- Auto-detects session type (X11 vs Wayland)
- Selects appropriate backend automatically
- Provides helpful error messages when shortcuts unavailable
- Added `evdev>=1.6.0` to dependencies (Linux only)
- Comprehensive test updates:
- 21 tests pass covering all backends
- Tests for session detection
- Tests for backend factory
- Tests for permission hints
**User Impact:**
- Keyboard shortcuts now work on Wayland when user is in 'input' group
- Clear error messages guide users to fix permission issues
- Backward compatible with X11 (pynput backend)
**Setup for Wayland:**
```bash
sudo usermod -a -G input $USER
# Log out and log back in
```

* feat: add language selector UI with auto-detection support
This commit implements a comprehensive language selector for the GUI,
extending support from 4 to 10 languages and adding Whisper auto-detect.
Changes:
- Add SUPPORTED_LANGUAGES constant with 10 languages (auto, en-us, hi, es, fr, de, it, pt, ru, zh)
- Each language includes display name, Whisper code, VOSK model name, and optional warning
- Extend VOSK_MODEL_INFO to include Hindi, Spanish, Italian, Portuguese, and Chinese models
- Add language dropdown in Settings dialog with status indicators (✓ downloaded, ↓ needs download, ⚠ warning)
- Add language warning label for auto-detect and engine compatibility messages
- Update default language from "en-us" to "auto" for Whisper auto-detection
- Handle "auto" language in Whisper (passes None for auto-detect)
- Handle "auto" language in VOSK (falls back to "en-us" since VOSK doesn't support auto-detect)
- Update CLI --language argument to include all supported languages
Fixes the issue where Hindi speech was being transcribed as English
because the language was hardcoded to "en-us" which Whisper interpreted
as "force English transcription" rather than auto-detect.

* style: format main.py with black
* fix: use venv python and set GI_TYPELIB_PATH for verification
* fix: create wrapper scripts that set GI_TYPELIB_PATH
Problem: The symlinks in ~/.local/bin pointed to venv scripts that
failed because PyGObject couldn't find the system typelib files
(AppIndicator3 namespace not available).
Solution: Create wrapper scripts in ~/.local/bin that:
1. Set GI_TYPELIB_PATH=/usr/lib/girepository-1.0
2. Execute the venv's vocalinux scripts
This fixes the issue where vocalinux-gui would fail to start with:
ValueError: Namespace AppIndicator3 not available
* fix: set GI_TYPELIB_PATH in desktop entry Exec line
When launching from the app drawer, the environment variables from the
wrapper script weren't being inherited properly. By adding GI_TYPELIB_PATH
directly in the desktop entry's Exec line, the app can now find the
AppIndicator3 typelib files.
* fix: always create wrapper scripts, not just for remote installs
The wrapper scripts were only created when CLEANUP_ON_EXIT=yes, which
is only set for remote (curl-based) installations. When running from
a local repository, the wrapper scripts were never created, causing
the desktop entry and launch commands to fail.
* fix: prevent recursion in LoggingHandler when processing log records
The custom LoggingHandler was triggering logging from within the logging
system itself, causing infinite recursion when formatting log records.
This could happen when the logging formatter or any operation during
record processing triggered additional log messages.
Fix: Add _emitting flag to prevent recursive calls to emit().
* fix: prevent infinite loop in settings dialog when changing language
Add guard flags to prevent recursive event handler calls:
- _populating_models: blocks _on_model_changed during model population
- _processing_language_change: blocks recursive language change handling
- _applying_settings: blocks recursive settings application
These guards prevent the infinite loop that occurred when selecting a
language whose VOSK model wasn't downloaded yet.
Fixes issue where "Model small needs download" logged repeatedly.
* fix: handle language parameter in reconfigure and improve UX
- Fix reconfigure() to properly handle language parameter changes
- Remove _processing_language_change check from _auto_apply_settings
to allow settings to be applied when language changes
- Hide unsupported languages in dropdown based on selected engine
* VOSK: only show languages with available models (no "auto")
* Whisper: show all supported languages including "auto"
- Remove duplicate _auto_apply_settings call in _on_engine_changed
- Set active language in combo after repopulating options
This fixes:
1. Whisper continuing to use old language after switching (e.g.,
still transcribing in Hindi after switching to en-us)
2. Potential infinite loop when selecting languages for VOSK
3. User confusion by showing incompatible language options
