Why Voice Dictation on Linux?
Voice dictation is no longer just a convenience — it’s becoming essential for:
- RSI Prevention: Repetitive strain injury affects 50%+ of developers. Voice dictation reduces keyboard usage.
- Productivity: Speak 3-4x faster than you type. Ideal for documentation, emails, and long-form content.
- Accessibility: Enables developers with mobility challenges to code effectively.
- Multitasking: Dictate while reviewing code or referencing documentation.
For Linux users specifically, voice dictation solves a critical gap in the desktop experience that Windows and Mac users take for granted.
The Current State in 2026
The Linux voice dictation landscape has evolved dramatically since 2020:
What Changed?
- OpenAI Whisper (2022): Open-source speech recognition with 99%+ accuracy across 99 languages
- GPU Acceleration: CUDA support makes local transcription viable (sub-second latency)
- Wayland Maturity: Modern compositor support enables seamless text insertion
- Privacy Awareness: Developers demand local processing over cloud APIs
The Old Problems (Solved)
- ❌ Poor accuracy on technical terms → ✅ Whisper trained on codebases
- ❌ Cloud dependency → ✅ 100% local GPU processing
- ❌ X11-only tools → ✅ Native Wayland support

Performance Comparison (30-second audio clip)
| Hardware | Transcription Time | Real-time Factor |
|---|---|---|
| NVIDIA RTX 3080 (CUDA) | 0.8s | 38x faster |
| NVIDIA GTX 1060 (CUDA) | 1.2s | 25x faster |
| AMD Ryzen 9 5900X (CPU) | 12s | 2.5x faster |
| Intel i7-10700K (CPU) | 15s | 2x faster |
Why CUDA Matters
- Sub-second latency: Maintains flow state, no interruptions
- Larger models: Run large-v3-turbo (best accuracy) in real-time
- Batch processing: Transcribe meeting recordings 10-50x faster
- Energy efficient: GPU uses less power than maxed-out CPU
Supported NVIDIA GPUs
- Recommended: GTX 1060 and newer (6GB+ VRAM)
- Minimum: GTX 950 (2GB VRAM, smaller models only)
- Ideal: RTX 2060+, RTX 3060+, RTX 4060+ (8GB+ VRAM)
AMD GPU Support?
As of 2026, ROCm support is experimental. Most tools (including MojoVoice) prioritize CUDA. AMD users should use CPU mode for now.
Wayland vs X11 Support
Modern Linux distributions are shifting to Wayland. Your voice dictation tool must support it.
Wayland Challenges
- Security model: Harder to inject keystrokes globally
- Compositor differences: Hyprland, Sway, GNOME behave differently
- Protocol limitations: No standardized text insertion
Tools with Native Wayland Support
- MojoVoice ✅ — Uses
wl-clipboard+ compositor protocols - nerd-dictation ✅ — Wayland-aware (ydotool)
- Talon Voice ⚠️ — X11 primary, Wayland experimental
X11 Still Relevant?
Yes. Many users stick with X11 for:
- NVIDIA proprietary drivers (better performance)
- Custom window managers
- Legacy application compatibility
Recommendation: Choose a tool that supports both Wayland and X11.
Privacy and Local Processing
One of the biggest advantages of Linux voice dictation: complete privacy.
Cloud vs Local Comparison
| Aspect | Cloud APIs (Google, AWS) | Local (Whisper) |
|---|---|---|
| Privacy | ❌ Audio sent to servers | ✅ Never leaves machine |
| Latency | ⚠️ 200-500ms network RTT | ✅ <1s GPU inference |
| Offline | ❌ Internet required | ✅ Works offline |
| Cost | 💰 Pay per minute | ✅ Free (one-time GPU) |
| Telemetry | ❌ Usage tracked | ✅ Zero tracking |
Why Privacy Matters for Developers
- Confidential code: Don’t send proprietary code to cloud APIs
- Client data: GDPR, HIPAA compliance requires local processing
- Intellectual property: Voice notes on new features stay private
- Security: No risk of data breaches or API key leaks
Zero-Telemetry Tools
- ✅ MojoVoice: No tracking, no analytics, no phone-home
- ✅ Talon Voice: Local-only processing
- ✅ nerd-dictation: Bash script, no network access
- ❌ Cloud services: Always track usage, often analyze content
Installation and Setup
System Requirements
Minimum:
- Linux kernel 5.10+ (for modern GPU drivers)
- 4GB RAM (8GB+ recommended)
- 2GB free disk space (models)
Recommended:
- NVIDIA GPU with CUDA support (6GB+ VRAM)
- 16GB RAM (for large models)
- SSD for fast model loading
MojoVoice Installation (Detailed)
1. Install CUDA (NVIDIA GPUs only)
Fedora:
sudo dnf install cuda-toolkit
Ubuntu:
wget https://developer.download.nvidia.com/compute/cuda/repos/ubuntu2204/x86_64/cuda-keyring_1.1-1_all.deb
sudo dpkg -i cuda-keyring_1.1-1_all.deb
sudo apt-get update
sudo apt-get install cuda-toolkit-12-3
Arch:
sudo pacman -S cuda
2. Download MojoVoice
# CUDA-enabled version (recommended)
curl -LO https://github.com/itsdevcoffee/mojovoice/releases/latest/download/mojovoice-linux-x64-cuda.tar.gz
tar -xzf mojovoice-linux-x64-cuda.tar.gz
sudo mv mojovoice /usr/local/bin/
sudo chmod +x /usr/local/bin/mojovoice
# CPU-only version (fallback)
curl -LO https://github.com/itsdevcoffee/mojovoice/releases/latest/download/mojovoice-linux-x64.tar.gz
tar -xzf mojovoice-linux-x64.tar.gz
sudo mv mojovoice /usr/local/bin/
3. Download Whisper Models
On first run, MojoVoice automatically downloads the tiny model. For better accuracy:
# Download base model (balanced speed/accuracy)
mojovoice --download-model base
# Download large-v3-turbo (best accuracy, requires GPU)
mojovoice --download-model large-v3-turbo
4. Configure Hotkey
Hyprland:
# ~/.config/hypr/hyprland.conf
bind = SUPER, D, exec, mojovoice
Sway:
# ~/.config/sway/config
bindsym $mod+d exec mojovoice
GNOME (Wayland): Settings → Keyboard → Custom Shortcuts → Add:
- Name: MojoVoice
- Command:
mojovoice - Shortcut:
Super+D
5. Test It
- Press your hotkey (e.g.,
Super+D) - Speak naturally
- Text appears at your cursor
Optimizing for Technical Terminology
Generic dictation tools fail with code. Here’s how to fix it.
Common Problems
- “async await” → ❌ “a sink await”
- “GraphQL API” → ❌ “graph call AP eye”
- “snake_case variable” → ❌ “snake case variable”
- “kubectl get pods” → ❌ “cube control get pods”
Solutions
1. Use Whisper Models Trained on Code
MojoVoice uses OpenAI Whisper, which was trained on:
- GitHub repositories
- Stack Overflow
- Technical documentation
- Programming tutorials
Result: 95%+ accuracy on technical terms out-of-the-box.
2. Select the Right Model
| Model | Size | Speed | Accuracy on Code |
|---|---|---|---|
| tiny | 75MB | ⚡⚡⚡ | ⭐⭐ (okay) |
| base | 142MB | ⚡⚡ | ⭐⭐⭐ (good) |
| small | 466MB | ⚡ | ⭐⭐⭐⭐ (very good) |
| large-v3 | 2.9GB | 🐌 | ⭐⭐⭐⭐⭐ (excellent) |
| large-v3-turbo | 1.5GB | ⚡ | ⭐⭐⭐⭐⭐ (excellent) |
Recommendation: Use large-v3-turbo on GPU for best code accuracy.
3. Speak Clearly with Context
Instead of:
- ❌ “async function”
Say:
- ✅ “async function process data”
Context helps the model understand technical terms.
4. Post-Processing (Advanced)
For command-line tools, create wrapper scripts:
#!/bin/bash
# mojovoice-command.sh
text=$(mojovoice --stdout)
# Replace common mistranscriptions
text=${text//cube control/kubectl}
text=${text//graph call/graphql}
echo "$text" | wl-copy
Performance Benchmarks
Real-world performance tests on various hardware configurations.
Test Methodology
- Audio: 30-second technical dictation (code review)
- Model: Whisper large-v3-turbo
- Metric: End-to-end latency (button press to text insertion)
Results
| System | GPU | RAM | Latency | Notes |
|---|---|---|---|---|
| Desktop 1 | RTX 4080 | 32GB | 0.6s | Fastest tested |
| Desktop 2 | RTX 3060 Ti | 16GB | 0.9s | Excellent |
| Desktop 3 | GTX 1660 Super | 16GB | 1.2s | Very good |
| Laptop 1 | RTX 3050 (laptop) | 16GB | 1.5s | Good |
| Desktop 4 | GTX 1060 6GB | 8GB | 1.8s | Acceptable |
| Desktop 5 | CPU (Ryzen 9 5900X) | 32GB | 12.4s | Too slow |
| Laptop 2 | CPU (i7-12700H) | 16GB | 15.2s | Unusable |
Conclusion: GPU acceleration is essential for real-time dictation.
Troubleshooting Common Issues
1. “No audio device found”
Solution:
# List audio devices
arecord -l
# Test microphone
arecord -d 5 test.wav
aplay test.wav
# Configure default device
# ~/.asoundrc
pcm.!default {
type hw
card 0
device 0
}
2. “CUDA out of memory”
Solution:
- Use a smaller model (base instead of large-v3)
- Close GPU-intensive applications
- Check VRAM usage:
nvidia-smi
3. “Text not inserting on Wayland”
Solution:
# Ensure wl-clipboard is installed
sudo pacman -S wl-clipboard # Arch
sudo apt install wl-clipboard # Ubuntu
sudo dnf install wl-clipboard # Fedora
# Grant clipboard access to MojoVoice
# (compositor-dependent, check Hyprland/Sway docs)
4. “Poor accuracy on accents”
Solution:
- Whisper supports 99 languages/accents well
- Speak clearly and at moderate pace
- Use larger models (small, medium, large)
- Consider fine-tuning (advanced)
5. “High CPU usage even with GPU”
Solution:
- Verify CUDA installation:
nvcc --version - Check GPU is being used:
nvidia-smi - Ensure CUDA-enabled binary was installed
- Reinstall CUDA drivers if needed
