* 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)
