* feat: Make Whisper tiny the default engine and download during install
- Changed default engine from 'vosk' to 'whisper' in config_manager.py
- Changed default model_size from 'small' to 'tiny' in config_manager.py
- Added install_whisper_model() function to install.sh that downloads
the Whisper tiny model (~75MB) during installation
- Whisper model is downloaded when Whisper package is installed
(in non-interactive mode or with --with-whisper flag)
- Updated installation summary to show Whisper model status
- Updated documentation (README.md, INSTALL.md, SECURITY.md, USER_GUIDE.md)
to reflect Whisper tiny as the default engine
This provides a better out-of-box experience: users can install and
immediately use Vocalinux without any additional downloads or prompts.
* test: Update test to reflect whisper as default engine
* fix: install/uninstall scripts for curl | bash usage
Install script improvements:
- Detect non-interactive mode (curl | bash) automatically
- Skip interactive prompts in non-interactive mode
- Add --no-whisper and -y/--yes flags for explicit control
- Continue with defaults when stdin is not a tty
Uninstall script improvements:
- Clean up curl-installed files:
- ~/.local/share/vocalinux-install (cloned repo)
- ~/.local/share/vocalinux/venv (virtual environment)
- ~/.local/bin/vocalinux (symlink)
- ~/.local/bin/activate-vocalinux.sh
- Add -y/--yes flag for non-interactive mode
- Verify all curl-installed components are removed
README updates:
- Document curl installation with --with-whisper option
- Add uninstall instructions for both methods
- Clarify what gets installed where
* feat: install Whisper by default in non-interactive mode
- curl | bash now installs both VOSK and Whisper out of the box
- Users can freely switch between engines in settings
- Add --no-whisper flag for faster install (VOSK only)
- Update README to reflect new default behavior
* chore: remove install-whisper.sh (now part of install.sh)
Whisper is installed by default via install.sh, making this
separate script redundant.
* chore: remove activate-vocalinux.sh (generated by install.sh)
This file is dynamically created by install.sh based on the
venv location, so the static template is not needed.
* feat: Implement comprehensive Whisper speech recognition support

when trying to use Whisper without proper installation, providing
clear guidance and multiple solutions for different scenarios.
* feat: Enhance Whisper support and improve Settings UI
## Whisper Implementation Fixes
- Fix Whisper transcription by removing unnecessary audio padding
- Fix API usage: pass numpy array directly instead of torch tensor
- Remove confusing model size remapping (users select exact model names)
- Add fp16=False for CPU to prevent warnings
- Fix missing 'import torch' in install-whisper.sh verification
## Audio System Improvements
- Add ALSA error handler to suppress noisy warnings
- Process remaining audio buffer when stopping recognition (fixes test button)
## Settings Dialog UI Enhancements
- Add model metadata display (download status, size, recommendations)
- Show ✓ for downloaded models, ↓ for pending downloads, ★ for recommended
- Add system-based model recommendations (based on RAM/GPU)
- Implement auto-apply settings on change (remove Apply button)
- Fix VOSK settings visibility when Whisper is selected
- Add VOSK model info panel with same features as Whisper
- Fix test recognition to show results in dialog instead of injecting text
- Fix race condition in test result display
## Startup Improvements
- Load saved config on startup (engine/model now persists correctly)
- Settings are remembered between app restarts
## Code Quality
- Add get_text_callbacks/set_text_callbacks methods for test isolation
- Update tests with proper mocking
* feat: Package VOSK model with installation for faster first-run experience
🚀 Installation Improvements:
- Add VOSK small model download during installation process
- Eliminate first-run model download delay for better user experience
- Add --skip-models option for offline installations
- Include wget, curl, unzip in system dependencies for model download

- Add multi-location model search (user, system-wide, pre-installed)
- Prioritize pre-installed models over downloads
- Add informative logging for model source detection
- Create marker files to identify installer-provided models
📦 Installation Script Features:

- Comprehensive error handling and cleanup
- Installation summary includes model status
🔧 Recognition Manager Updates:
- Check multiple model locations in priority order:
1. User's local models directory
2. System-wide installation directories
3. Download to user directory if not found
- Enhanced logging for model source identification
- Backward compatibility with existing installations
💡 Benefits:
- Faster application startup (no initial model download)
- Better offline installation support
- Reduced first-run friction for users
- Maintains fallback to runtime download if needed
- Clear feedback about model installation status
This addresses the issue where users had to wait for model downloads
on first application launch, making VocaLinux ready to use immediately
after installation.
* fix: Move install_vosk_models function definition before its call
The function was being called before it was defined, causing a
'command not found' error during installation. Fixed by moving
the function definition to before the installation steps where
it's called.
This resolves the installation error:
./install.sh: line 701: install_vosk_models: command not found
