Parakeet Dictation Skill
Local speech-to-text powered by NVIDIA Parakeet TDT 0.6B V3 (~600MB model, 100% offline).
Two Modes
1. Handy App (Primary — Push-to-Talk into Any Text Field)
Handy is a free, open-source Tauri app (Rust + React) providing push-to-talk dictation with Parakeet V3 built in. Inference via transcribe-rs (ONNX Runtime, int8 quantized).
brew install --cask handy
- •Default hotkey: ⌥Space (Option-Space) on macOS, Ctrl-Space on Windows/Linux
- •Modes: Push-to-talk (hold) or toggle (press to start/stop)
- •Select Parakeet V3 in Settings → Models (auto-downloads ~478MB)
- •Grant microphone + accessibility permissions
- •Includes VAD (Silero), model management UI
- •Additional models: Whisper (Small/Medium/Turbo/Large), Moonshine, SenseVoice
- •Models stored at
~/Library/Application Support/com.pais.handy/models/
2. CLI Scripts (Claude Code File Transcription & Terminal Dictation)
CLI scripts remain for headless/terminal use within Claude Code. These use NeMo/PyTorch.
Performance
| System | Speed | Engine |
|---|---|---|
| Handy (M4 Max) | ~30x realtime | transcribe-rs / ONNX int8 |
| Handy (Zen 3) | ~20x realtime | transcribe-rs / ONNX int8 |
| Handy (Skylake i5) | ~5x realtime | transcribe-rs / ONNX int8 |
| NeMo CLI (MPS) | Varies | NeMo / PyTorch |
- •Accuracy: 6.05% WER (Word Error Rate)
- •Languages: 25 European languages with automatic detection (no prompting)
- •Privacy: 100% local processing, no cloud API
- •License: CC BY 4.0 (model), MIT (Handy app)
Commands
Transcribe Audio File
/parakeet path/to/audio.wav /parakeet ~/recordings/interview.mp3 /parakeet meeting.m4a
Supported formats: .wav, .mp3, .m4a, .flac, .ogg, .aac
Live Dictation (Terminal)
/parakeet /parakeet dictate
Record from microphone until Enter is pressed, then transcribe.
Check Installation
/parakeet check
Verify Parakeet is properly installed and model can load.
Setup
Handy (Push-to-Talk UI)
brew install --cask handy
Launch from Applications, select Parakeet V3 model, configure hotkey.
CLI Scripts (Prerequisites)
- •Parakeet Dictate repo at
~/Programming/parakeet-dictate/with Python venv - •Install dependencies:
bash
cd ~/Programming/parakeet-dictate uv venv && uv pip install -r requirements.txt
- •(Optional) Set custom path:
export PARAKEET_HOME=/path/to/parakeet-dictate
Implementation
When this skill is invoked:
- •
For audio files: Run the transcription script
bashcd ~/.claude/skills/parakeet/scripts && \ ${PARAKEET_HOME:-~/Programming/parakeet-dictate}/.venv/bin/python transcribe.py "<filepath>" - •
For live dictation: Run the dictation script
bashcd ~/.claude/skills/parakeet/scripts && \ ${PARAKEET_HOME:-~/Programming/parakeet-dictate}/.venv/bin/python dictate.py - •
For checking setup: Run the check script
bashcd ~/.claude/skills/parakeet/scripts && \ ${PARAKEET_HOME:-~/Programming/parakeet-dictate}/.venv/bin/python check_setup.py
Model Caches
| System | Cache Location | Size | Engine |
|---|---|---|---|
| Handy | ~/Library/Application Support/com.pais.handy/models/ | ~478MB | transcribe-rs (ONNX int8) |
| NeMo CLI | ~/.cache/nemo/ | ~1.2GB | NeMo / PyTorch |
Model caches are separate. Handy's Parakeet V3 int8 model structure:
parakeet-tdt-0.6b-v3-int8/ ├── encoder-model.int8.onnx ├── decoder_joint-model.int8.onnx ├── nemo128.onnx (audio preprocessor) └── vocab.txt
Troubleshooting
"No module named nemo"
Use the Parakeet virtual environment. Scripts automatically use the correct Python.
"MPS not available"
Apple Silicon Metal acceleration requires PyTorch 2.0+. Falls back to CPU automatically.
"Permission denied: microphone"
Grant microphone access in System Preferences → Privacy & Security → Microphone.
Model download slow
The Parakeet model downloads on first use (~478MB for Handy, ~1.2GB for NeMo). Subsequent runs use cache.
Configuration
| Variable | Default | Description |
|---|---|---|
PARAKEET_HOME | ~/Programming/parakeet-dictate | Parakeet Dictate installation path |
Dependencies
Handy: brew install --cask handy (standalone, no other deps)
CLI scripts require:
- •Parakeet Dictate repo at
$PARAKEET_HOME(default:~/Programming/parakeet-dictate) - •Python virtual environment at
$PARAKEET_HOME/.venv - •NeMo toolkit with ASR support (
nemo_toolkit[asr]>=2.0.0) - •PyTorch 2.0+ (for MPS/CUDA acceleration)
- •soundfile and sounddevice for audio handling
