# Voice
|
|
|
|
Paseo has first-class voice support for dictation and realtime conversations with your coding environment.
|
|
|
|
## Philosophy
|
|
|
|
Voice is local-first. You can run speech fully on-device, or choose OpenAI for speech features. For voice reasoning/orchestration, Paseo reuses agent providers already installed and authenticated on your machine.
|
|
|
|
This keeps credentials and execution in your environment and avoids introducing a separate cloud-only voice stack.
|
|
|
|
## Architecture
|
|
|
|
- Speech I/O: STT and TTS providers per feature (`local` or `openai`)
|
|
- Local speech runtime: ONNX models executed on CPU by default
|
|
- Voice LLM orchestration: hidden agent session using your configured provider (`claude`, `codex`, or `opencode`)
|
|
- Tooling path: MCP stdio bridge for voice tools and agent control
|
|
|
|
## Local Speech
|
|
|
|
Local speech defaults to model IDs `parakeet-tdt-0.6b-v3-int8` (STT) and `kokoro-en-v0_19` (TTS, speaker 0 / voice 00).
|
|
|
|
Missing models are downloaded at daemon startup into `$PASEO_HOME/models/local-speech`. Downloads happen only for missing files.
|
|
|
|
```json
|
|
{
|
|
"version": 1,
|
|
"features": {
|
|
"dictation": { "stt": { "provider": "local", "model": "parakeet-tdt-0.6b-v3-int8" } },
|
|
"voiceMode": {
|
|
"llm": { "provider": "claude", "model": "haiku" },
|
|
"stt": { "provider": "local", "model": "parakeet-tdt-0.6b-v3-int8" },
|
|
"tts": { "provider": "local", "model": "kokoro-en-v0_19", "speakerId": 0 }
|
|
}
|
|
},
|
|
"providers": {
|
|
"local": {
|
|
"modelsDir": "~/.paseo/models/local-speech"
|
|
}
|
|
}
|
|
}
|
|
```
|
|
|
|
## OpenAI Speech Option
|
|
|
|
You can switch dictation, voice STT, and voice TTS to OpenAI by setting provider fields to `openai` and providing `OPENAI_API_KEY`.
|
|
|
|
```json
|
|
{
|
|
"version": 1,
|
|
"features": {
|
|
"dictation": { "stt": { "provider": "openai" } },
|
|
"voiceMode": {
|
|
"stt": { "provider": "openai" },
|
|
"tts": { "provider": "openai" }
|
|
}
|
|
},
|
|
"providers": {
|
|
"openai": { "apiKey": "..." }
|
|
}
|
|
}
|
|
```
|
|
|
|
## Environment Variables
|
|
|
|
- `OPENAI_API_KEY`, OpenAI speech credentials
|
|
- `PASEO_VOICE_LLM_PROVIDER`, voice agent provider override
|
|
- `PASEO_LOCAL_MODELS_DIR`, local model storage directory
|
|
- `PASEO_DICTATION_LOCAL_STT_MODEL`, local dictation STT model ID
|
|
- `PASEO_VOICE_LOCAL_STT_MODEL`, `PASEO_VOICE_LOCAL_TTS_MODEL`, local voice STT/TTS model IDs
|
|
- `PASEO_VOICE_LOCAL_TTS_SPEAKER_ID`, `PASEO_VOICE_LOCAL_TTS_SPEED`, optional local voice TTS tuning
|
|
|
|
## Operational Notes
|
|
|
|
Realtime voice can launch and control agents. Treat voice prompts with the same care as direct agent instructions, especially when specifying working directories or destructive operations.
