* fix(injection): read WM_CLASS with xprop so xdotool stops dumping core
`xdotool getwindowclassname` hands an uninitialized XClassHint to XFree
when the window carries no WM_CLASS, so it aborts with SIGABRT
("free(): invalid size") and leaves a coredump behind. On KDE Plasma
Wayland that is the normal case, not an edge case: while a native
Wayland client holds focus, KWin points XWayland's _NET_ACTIVE_WINDOW at
a property-less window, and `xdotool getactivewindow` reports it happily.
Every paste-shortcut probe therefore killed a child process and filled
the journal with coredumps. Injection still worked, because the abort
only made the probe return an empty class, so the symptom was silent
except in `coredumpctl`.
read_wm_class() now reads the property with xprop, which handles a
missing WM_CLASS as an ordinary empty result, and falls back to xdotool
only when xprop is absent and the window looks like a real client (it has
a pid or a title). The debug window-info logging in text_injector.py goes
through the same helper.
Reproduced on Fedora 44, Plasma 6 Wayland, xdotool 3.20211022.1:
`xdotool getwindowclassname 0x200000` exits 134 on the window that
`_NET_ACTIVE_WINDOW` points at.
* fix(injection): keep xdotool classname for class-only X11 clients
When xprop is missing, always allow the xdotool classname fallback so a
real terminal that exposes WM_CLASS but no title or _NET_WM_PID still
classifies as a terminal (Ctrl+Shift+V). xprop remains the primary path,
so Plasma Wayland with xprop never calls getwindowclassname.

Vocalinux turns speech into typed text in whatever app has focus. It is a free, AGPL-3.0-licensed desktop app for X11 and Wayland. After you download a model, local engines (whisper.cpp by default, plus OpenAI Whisper, Faster Whisper, VOSK, and Parakeet) run speech-to-text on your machine. An optional remote HTTP API is off unless you configure it.
No Voca account is required. Models download once. After that, speech-to-text stays on your machine.
Current release: v0.16.2. Stability patch on the 0.16 series (KDE leftover IBus, Wayland/IBus shortcuts, BackSpace for "delete that", installer glslc, release integrity pins). Series highlights include the in-app update checker, Right Alt push-to-talk for new installs, searchable languages, unused-model cleanup, and the family tone picker. Details: docs/UPDATE.md.
Features
- On-device after model download: Local engines; speech-to-text stays on your machine
- X11 and Wayland: Text injection via xdotool, IBus, wtype, ydotool, or clipboard fallback
- Several engines: whisper.cpp (default), OpenAI Whisper, Faster Whisper, VOSK, Parakeet, plus optional remote HTTP API
- GPU acceleration: Vulkan for AMD, Intel, and NVIDIA with whisper.cpp
- Toggle or push-to-talk: New installs default to hold Right Alt; existing configs keep their shortcut
- System tray + settings: Searchable sidebar, Speech Model simple setup with Advanced as an island, status icons, audio feedback
- Start on login: XDG autostart (desktop session, not a systemd service)
- Packaging: install script, AppImage, AUR, PyPI, Snap (
--edge), Flatpak (release bundles and local build; not on Flathub)

Install
Recommended (interactive installer)
curl -fsSL https://raw.githubusercontent.com/VocaHQ/vocalinux/main/install.sh -o /tmp/vl.sh
bash /tmp/vl.sh
Prefer to review the script first: open /tmp/vl.sh before running it, or clone the repo and run ./install.sh locally.
The installer detects hardware, recommends an engine, downloads a default model (~74MB for whisper.cpp tiny), installs neural VAD when ONNX Runtime is available, and sets up desktop integration. Typical install time with whisper.cpp is about 1-2 minutes.
| Engine | When to use |
|---|---|
| whisper.cpp (default) | Best default; Vulkan GPU on AMD, Intel, and NVIDIA |
| Whisper (OpenAI) | PyTorch path; NVIDIA/CUDA |
| Faster Whisper | CPU-friendly Whisper via CTranslate2 / INT8 |
| VOSK | Low RAM / minimal footprint |
| Parakeet | CPU; NVIDIA NeMo ASR via sherpa-onnx; 25 European languages |
| Remote API | Offload to a server you configure |
Non-interactive options:
bash /tmp/vl.sh --auto # whisper.cpp defaults
bash /tmp/vl.sh --auto --engine=whisper # OpenAI Whisper
bash /tmp/vl.sh --auto --engine=faster_whisper # Faster Whisper (CPU)
bash /tmp/vl.sh --auto --engine=vosk # VOSK only
bash /tmp/vl.sh --auto --engine=parakeet # Parakeet (CPU)
For a specific release tag, see GitHub Releases or ./install.sh --tag=v0.16.2.
Arch Linux (AUR)
yay -S vocalinux
See docs/AUR.md.
AppImage
Download the x86_64 or aarch64 AppImage from Releases, mark it executable, and run it. Built against glibc 2.35 (Debian 12+, Ubuntu 22.04+, Fedora 36+, Arch, Tumbleweed). Host text-injection tools (xdotool on X11; wtype / ydotool / clipboard tools on Wayland) are still required. Current AppImages rebuild whisper.cpp with Vulkan and use the host GPU driver. Prefer the installer when you want system deps, a CUDA build, and models set up automatically.
Flatpak (any distro)
GitHub Releases attach Vocalinux-<version>-x86_64.flatpak and Vocalinux-<version>-aarch64.flatpak. After the Flathub GNOME runtime is present:
flatpak install --user ./Vocalinux-<version>-x86_64.flatpak
Bundles do not auto-update. Local build:
flatpak install flathub org.gnome.Platform//50 org.gnome.Sdk//50
flatpak-builder --user --install --force-clean build-dir \
packaging/flatpak/com.vocalinux.Vocalinux.yml
flatpak run com.vocalinux.Vocalinux
Ships whisper.cpp with Vulkan. It is not on Flathub (submission flathub#9368 closed 2026-07-23 on policy grounds). Details: packaging/flatpak/README.md.
Snap (Ubuntu Snap Store)
Listing: snapcraft.io/vocalinux. stable is still a manual promote after QA.
sudo snap install vocalinux --edge
sudo snap connect vocalinux:audio-record # if mic is not auto-connected
sudo snap connect vocalinux:raw-input # global keyboard shortcuts (evdev)
From source
git clone https://github.com/VocaHQ/vocalinux.git
cd vocalinux
./install.sh
# or pick the engine up front
./install.sh --engine=whisper_cpp
./install.sh --engine=vosk
./install.sh --engine=parakeet --auto
After installation
vocalinux # if ~/.local/bin is on PATH
# or
~/.local/share/vocalinux/venv/bin/vocalinux
You can also launch Vocalinux from your application menu.
Nightly builds
Daily builds from main appear on Releases. Use the latest stable or beta release for production; nightlies are untested.
Requirements
| OS | Linux (Ubuntu 24.04+, Debian 12+, Fedora 42+, Arch, openSUSE Tumbleweed) |
| Python | 3.11 or newer |
| Display | X11 or Wayland |
| Hardware | Microphone; GPU optional (Vulkan) |
The distro must ship Python 3.11+ because Vocalinux uses distro PyGObject (python3-gi). Ubuntu 22.04 (Python 3.10) and Debian 11 (3.9) are below that floor. Distribution notes: docs/DISTRO_COMPATIBILITY.md.
Usage
Dictation
- Push-to-talk (default on new installs): hold Right Alt (Option on Mac-layout keyboards) and speak
- Speak into the microphone
- Release to stop, or switch to Toggle mode in Settings (double-tap a key to start/stop)
Existing configs keep their saved shortcut.
Voice commands
English phrases always work. With a non-English recognition language, matching punctuation / line-break phrases in that language are also recognized (Italian virgola / punto, French virgule / point, etc.).
| Command | Action |
|---|---|
| "new line" | Line break |
| "period" / "full stop" / "dot" | . |
| "comma" | , |
| "question mark" | ? |
| "exclamation mark" | ! |
| "delete that" | Delete last sentence |
| "capitalize" | Capitalize next word |

Autostart
Start on Login creates an XDG autostart desktop entry (~/.config/autostart/). It does not install a systemd unit. Enable from the first-run dialog, tray menu, or Settings.
Configuration
Stored at ~/.config/vocalinux/config.json. Prefer the Settings dialog for day-to-day changes. Settings → Speech Model starts with a simple setup; expand Advanced for engine, size, and specialization.
Neural VAD (Silero) is used when onnxruntime is available; install via pip install "vocalinux[vad]" for manual/PyPI installs. The installer attempts this automatically.
