Text-to-Speech synthesis endpoint
Convert text to speech audio using ComfyUI workflows.
- **text**: Text to synthesize
- **workflow**: TTS workflow key (optional, uses default if not specified)
- **ref_audio**: Reference audio for voice cloning (optional)
- **voice_id**: (Deprecated) Voice ID for legacy compatibility
Returns path to generated audio file and duration.
Examples:
```json
{
"text": "Hello, welcome to Pixelle-Video!",
"workflow": "runninghub/tts_edge.json"
}
```
With voice cloning:
```json
{
"text": "Hello, this is a cloned voice",
"workflow": "runninghub/tts_index2.json",
"ref_audio": "path/to/reference.wav"
}
```
