This commit implements comprehensive performance optimizations to improve the PageSpeed Insights score from 70/100 to targeting 90+. ## Images & Assets (Est. 200+ KiB savings) - Optimize vocalinux.png: 207KB → 44KB (79% reduction) - Add WebP versions for all logo sizes (32, 64, 96, 192, 512px) - Create og-image.webp: 274KB → 176KB (36% reduction) - All WebP images provide ~92% size reduction over PNG ## JavaScript Optimization (Est. 84 KiB savings) - Lazy load react-syntax-highlighter with next/dynamic - Created CodeBlock component for async code highlighting - Reduces initial bundle size by deferring heavy syntax highlighter ## Bundle Configuration - Disable production source maps (reduces bundle size) - Add .browserslistrc targeting modern browsers (est. 12 KiB savings) - Remove legacy browser polyfills (IE11, old Android, etc.) ## Critical Rendering Path (Est. 300ms LCP improvement) - Add preconnect hint for api.github.com - Defer Google Analytics to lazyOnload strategy ## Caching Strategy - Add cache headers configuration for static assets - Cache-Control: public, max-age=31536000, immutable - Applied to _next/static/* and image assets ## Accessibility Fixes - Fix footer color contrast: text-zinc-500 → text-zinc-400 - Add prefers-reduced-motion media query support - All animations respect user motion preferences ## Expected Impact - Total estimated LCP reduction: ~1.5-2 seconds - Bundle size reduction: ~100 KB - Targeting 90+ performance score (up from 70)
Vocalinux
Voice-to-text for Linux, finally done right!
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
One-liner Installation (Recommended)
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.
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
voskPython package from PyPI - Whisper: installs the
openai-whisperpackage from PyPI, which also pulls in PyTorch (the ML framework Whisper requires)
- VOSK: installs the
- 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
