🚀 Quick Install

Interactive Install (Recommended for New Users)

Let the installer guide you through the setup with smart hardware detection:

curl -fsSL https://raw.githubusercontent.com/jatinkrmalik/vocalinux/main/install.sh | bash -s -- --tag=v0.4.1-alpha --interactive

The interactive installer will:

• Auto-detect your hardware (GPU, RAM)
• Recommend the best configuration for your system
• Guide you through each step with clear explanations
• Show you how to launch and use Vocalinux after installation

One-liner Installation (Quick Install)

curl -fsSL https://raw.githubusercontent.com/jatinkrmalik/vocalinux/main/install.sh | bash -s -- --tag=v0.4.1-alpha

Note

: Installs v0.4.1-alpha. For the most recent version, check GitHub Releases.

GPU Detection: The installer now automatically detects NVIDIA GPUs and uses CPU-only PyTorch when no GPU is present, saving you ~2GB of download!

This will:

• Clone the repository to ~/.local/share/vocalinux-install
• Install all system dependencies
• Set up a virtual environment in ~/.local/share/vocalinux/venv
• Install both VOSK and Whisper AI speech engines:
  • VOSK: installs the vosk Python package from PyPI
  • Whisper: installs the openai-whisper package from PyPI, which also pulls in PyTorch (the ML framework Whisper requires)
• Create a symlink at ~/.local/bin/vocalinux
• Download the default Whisper tiny speech model (~75MB)

⏱️ Note: Installation takes ~5-10 minutes due to Whisper AI dependencies (PyTorch with CUDA support, ~2.3GB).

Whisper with CPU-only PyTorch (no NVIDIA GPU needed):

curl -fsSL https://raw.githubusercontent.com/jatinkrmalik/vocalinux/main/install.sh | bash -s -- --tag=v0.4.1-alpha --whisper-cpu

This installs Whisper with CPU-only PyTorch (~200MB instead of ~2.3GB). Works great for systems without NVIDIA GPU.

For low-RAM systems (8GB or less) - VOSK only:

curl -fsSL https://raw.githubusercontent.com/jatinkrmalik/vocalinux/main/install.sh | bash -s -- --tag=v0.4.1-alpha --no-whisper

This skips Whisper installation entirely and configures VOSK as the default engine.

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.

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!

Uninstall

# If installed via curl:
curl -fsSL https://raw.githubusercontent.com/jatinkrmalik/vocalinux/main/uninstall.sh | bash

# If installed from source:
./uninstall.sh

🔊 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.
