vocalinux 0.10.2b0

A seamless voice dictation system for Linux

Vocalinux

Voice-to-text for Linux, finally done right!

Linux has always punched above its weight, except when it comes to voice typing. Vocalinux fixes that.

It's a free, GPLv3-licensed desktop app that lets you dictate text into any application, on X11 or Wayland, using fully offline speech recognition. Pick from three engines (whisper.cpp, OpenAI Whisper, or VOSK), get automatic GPU acceleration via Vulkan, and control it all with customizable keyboard shortcuts: toggle or push-to-talk.

No internet required. No data leaves your machine. Just speak and type.

📚 What's New in v0.10.2-beta

🚀 Quick Install

Interactive Install (Recommended)

Our new interactive installer guides you through setup with intelligent hardware detection:

curl -fsSL raw.githubusercontent.com/jatinkrmalik/vocalinux/main/install.sh -o /tmp/vl.sh && bash /tmp/vl.sh

Choose your engine:

1. whisper.cpp ⭐ (Recommended) - Fast, works with any GPU via Vulkan
2. Whisper (OpenAI) - PyTorch-based, NVIDIA GPU only
3. VOSK - Lightweight, works on older systems

The installer will:

• Auto-detect your hardware (GPU, RAM, Vulkan support)
• Recommend the best engine for your system
• Download the appropriate model (~39MB for whisper.cpp tiny)
• Install in ~1-2 minutes (vs 5-10 min with old Whisper)

Note: Always installs the latest release. For a specific version, check GitHub Releases.

Installation Options

Default (whisper.cpp - recommended):

curl -fsSL raw.githubusercontent.com/jatinkrmalik/vocalinux/main/install.sh -o /tmp/vl.sh && bash /tmp/vl.sh

Fastest installation (~1-2 min), universal GPU support via Vulkan.

Whisper (OpenAI) - if you prefer PyTorch:

curl -fsSL raw.githubusercontent.com/jatinkrmalik/vocalinux/main/install.sh -o /tmp/vl.sh && bash /tmp/vl.sh --engine=whisper

NVIDIA GPU only (~5-10 min, downloads PyTorch + CUDA).

VOSK only - for low-RAM systems:

curl -fsSL raw.githubusercontent.com/jatinkrmalik/vocalinux/main/install.sh -o /tmp/vl.sh && bash /tmp/vl.sh --engine=vosk

Lightweight option (~40MB), works on systems with 4GB RAM.

Alternative: Install from Source

# Clone the repository
git clone https://github.com/jatinkrmalik/vocalinux.git
cd vocalinux

# Run the installer (will prompt for Whisper)
./install.sh

# Or with Whisper support
./install.sh --with-whisper

The installer handles everything: system dependencies, Python environment, speech models, and desktop integration.

🌙 Nightly Releases (Bleeding Edge)

For developers and early adopters who want to test the latest features, check out our GitHub Releases page which includes both beta and nightly builds.

⚠️ Warning: Nightly releases contain the absolute latest code and may be unstable. For production use, we recommend using the latest beta release.

Nightly builds are automatically generated from the main branch every day. They include all merged changes but haven't undergone the same testing as beta releases.

Release Channels:

• Beta (Recommended) - Tested pre-releases with known features
• Nightly - Untested bleeding edge with latest commits

After Installation

# If ~/.local/bin is in your PATH (recommended):
vocalinux

# Or activate the virtual environment first:
source ~/.local/bin/activate-vocalinux.sh
vocalinux

# Or run directly:
~/.local/share/vocalinux/venv/bin/vocalinux

Or launch it from your application menu!

📋 Requirements

• OS: Linux (tested on Ubuntu 22.04+, Debian 11+, Fedora 39+, Arch Linux, openSUSE Tumbleweed)
• Python: 3.9 or newer
• Display: X11 or Wayland
• Hardware: Microphone for voice input

Note: See Distribution Compatibility for distribution-specific information and experimental support for Gentoo, Alpine, Void, Solus, and more.

🎙️ Usage

Voice Dictation

1. Toggle mode: Double-tap the shortcut key (default Ctrl) to start recording
2. Speak clearly into your microphone
3. Toggle mode: Double-tap again (or pause speaking) to stop, or Push-to-Talk mode: release the key to stop

Voice Commands

Command	Action
"new line"	Inserts a line break
"period" / "full stop"	Types a period (.)
"comma"	Types a comma (,)
"question mark"	Types a question mark (?)
"exclamation mark"	Types an exclamation mark (!)
"delete that"	Deletes the last sentence
"capitalize"	Capitalizes the next word

Command Line Options

vocalinux --help                  # Show all options
vocalinux --debug                 # Enable debug logging
vocalinux --engine whisper_cpp    # Use whisper.cpp engine (default)
vocalinux --engine whisper        # Use OpenAI Whisper engine
vocalinux --engine vosk           # Use VOSK engine
vocalinux --model medium          # Use medium-sized model
vocalinux --wayland               # Force Wayland mode
vocalinux --start-minimized       # Start without first-run modal prompts

Autostart on Login

Vocalinux uses the Linux desktop standard for autostart:

• Mechanism: XDG autostart desktop entry (vocalinux.desktop)
• Path: $XDG_CONFIG_HOME/autostart/ or ~/.config/autostart/ (fallback)
• Launch mode: Starts as a regular user desktop app in your graphical session
• Not used: No systemd unit/service is created by Vocalinux for autostart

How to enable/disable:

• First-run welcome dialog
• Tray menu: Start on Login
• Settings dialog: Start on Login

Compatibility notes:

• Works on mainstream desktop environments (GNOME, KDE, Xfce, Cinnamon, MATE, LXQt)
• On minimal/custom window-manager sessions, an autostart handler may be required (for example DE-specific startup hooks or tools like dex)

⚙️ Configuration

Configuration is stored in ~/.config/vocalinux/config.json:

{
  "speech_recognition": {
    "engine": "whisper_cpp",
    "model_size": "tiny",
    "vad_sensitivity": 3,
    "silence_timeout": 2.0
  }
}

You can also configure settings through the graphical Settings dialog (right-click the tray icon).

🔊 Sound Customization

Vocalinux uses smooth, pleasant gliding tones for audio feedback:

• Start: Ascending F4→A4 (0.6s) - positive, uplifting
• Stop: Descending A4→F4 (0.6s) - resolves completion
• Error: Lower descending E4→C4 (0.7s) - gentle but noticeable

All sounds use pure sine waves with smoothstep interpolation for buttery smooth pitch transitions - perfect for headphone use!

Regenerate Sounds

To modify or regenerate the notification sounds:

python scripts/generate_sounds.py

This script generates all three sounds using the same smooth glide algorithm. You can edit the frequencies, durations, and amplitudes in the script to customize the sounds to your preference.
