Jatin K MalikandGitHub 7a6d0d4e2b feat: flexible Whisper installation options for different system configurations (#63)
* fix: VOSK-only install and CLI arg handling for low-memory systems

Fixes several issues reported by users on low-memory systems (8GB RAM):

1. Install script: Don't auto-install Whisper in non-interactive mode
   - Previously, running 'curl | bash' would install Whisper by default
   - Now requires explicit --with-whisper flag to install Whisper
   - Prevents OOM errors on systems with limited RAM

2. CLI arguments: Command-line flags now properly override saved config
   - --engine vosk now works even if config file has whisper set
   - --model flag also properly overrides saved model setting
   - Checks sys.argv to detect if user explicitly provided arguments

3. Default engine: Changed from 'whisper' to 'vosk'
   - VOSK works on low-memory systems without OOM issues
   - Users can still install and use Whisper with --with-whisper flag
   - Existing configs with 'whisper' engine are still respected

Reported issues:
- OOM during installation on 8GB RAM system
- vocalinux --engine vosk being ignored
- Config file not respected when trying to force VOSK

* fix: keep whisper as default engine, improve test robustness

- Reverted default engine back to 'whisper' for better accuracy
- Install script still defaults to VOSK-only install (--with-whisper for Whisper)
- CLI args still properly override saved config
- Improved test_config_manager tests to handle module caching issues

* fix: default to Whisper install, --no-whisper for VOSK-only on low-RAM systems

Updated install behavior:
- Default (curl|bash): Installs Whisper for best experience
- --no-whisper flag: Skips Whisper AND creates config with VOSK as default engine

This allows low-RAM users (8GB) to run:
  curl -fsSL .../install.sh | bash -s -- --no-whisper

Which will:
1. Skip installing torch/whisper (avoids OOM)
2. Create ~/.config/vocalinux/config.json with engine='vosk'
3. App will use VOSK by default without needing CLI flags

* docs: clarify --no-whisper is for low-RAM systems (8GB or less)

Updated README and website to explain that --no-whisper flag:
- Is intended for systems with 8GB RAM or less
- Avoids out-of-memory errors during installation
- Configures VOSK as the default speech recognition engine

* feat: add --whisper-cpu flag for CPU-only PyTorch installation

New installation option for users without NVIDIA GPU or with limited RAM:

Install script changes:
- Added --whisper-cpu flag: Installs CPU-only PyTorch (~200MB vs ~2.3GB)
- Uses https://download.pytorch.org/whl/cpu index for smaller torch package
- Interactive mode now offers 3 options: GPU, CPU-only, or skip Whisper
- Updated help text to explain all Whisper installation options

Documentation updates:
- README: Added --whisper-cpu example with explanation
- Website: Added new 'Whisper CPU-only' install option section

Installation options summary:
- Default (curl|bash): Whisper + GPU/CUDA support (~2.3GB, 5-10 min)
- --whisper-cpu: Whisper + CPU-only PyTorch (~200MB, 3-4 min)
- --no-whisper: VOSK only, no Whisper (~2-3 min)

Vocalinux Users

A seamless free open-source private voice dictation system for Linux, comparable to the built-in solutions on macOS and Windows.

🎉 Alpha Release!

We're excited to share Vocalinux with the community. Try it out and let us know what you think!


✨ Features

  • 🎤 Double-tap Ctrl to start/stop voice dictation
  • ⚡ Real-time transcription with minimal latency
  • 🌎 Universal compatibility across all Linux applications
  • 🔒 Offline operation for privacy and reliability (with VOSK)
  • 🤖 Optional Whisper AI support for enhanced accuracy
  • 🎨 System tray integration with visual status indicators
  • 🔊 Audio feedback for recording status
  • ⚙️ Graphical settings dialog for easy configuration

🚀 Quick Install

curl -fsSL https://raw.githubusercontent.com/jatinkrmalik/vocalinux/main/install.sh | bash

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
  • 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 -- --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 -- --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
