OminiX ASR / TTS / Model Management
On-device speech-to-text, preset-voice text-to-speech with emotion control, and model management using OminiX Qwen3 ASR/TTS models on Apple Silicon.
Voice cloning and custom voice profiles are handled by mofa-fm (fm_tts, fm_voice_save, fm_voice_list, fm_voice_delete). This skill only supports preset voices.
Configuration
The skill auto-discovers the ominix-api server URL via (in priority order):
OMINIX_API_URL environment variable- Discovery file
~/.ominix/api_url (written by ominix-api on startup)
- Default:
http://localhost:9090
Checking Available Models
Use list_models to see what's installed. The response includes an endpoints array for each model, telling you which URL to use:
{"data": [
{"id": "qwen3-asr", "type": "asr", "endpoints": ["/v1/audio/asr/qwen3"]},
{"id": "Qwen3-TTS-CustomVoice-8bit", "type": "qwen3_tts", "endpoints": ["/v1/audio/tts/qwen3"]}
]}
If a model you need is missing, use download_model then load_model to install it.
API Endpoints
| Function | Endpoint | Model |
|---|
| Preset TTS | POST /v1/audio/tts/qwen3 | Qwen3-TTS CustomVoice |
| Qwen3-ASR | POST /v1/audio/asr/qwen3 | Qwen3-ASR encoder-decoder |
| Paraformer | POST /v1/audio/asr/paraformer | Paraformer CTC-based |
TTS and ASR run on separate threads — they do not block each other.
