# Usage

## Quickstart

1. Get your API key and a usable `voiceId`.
2. Call `POST /sound_clone/api/v1/tts` for non-streaming output.
3. Call `POST /sound_clone/api/v1/tts/stream` for streaming output.
4. Use `modelId = myvocal_v3` for the V3 path.
5. For V3 language behavior:
   * Provide `language` for explicit target language control.
   * Omit `language` for auto-detect.

### Default path example

```bash theme={null}
curl --location 'https://api.myvocal.ai/sound_clone/api/v1/tts' \
--header 'accessKey: <your_api_key>' \
--header 'Content-Type: application/json' \
--data '{
  "voiceId": "<voice_id>",
  "title": "quickstart-default",
  "text": "Hello from MyVocal.",
  "language": "original_english"
}'
```
