# ModelsLab Audio Generation

Generate high-quality audio including speech, music, voice conversion, sound effects, and dubbing using AI.

## When to Use This Skill

- Convert text to natural-sounding speech (TTS)
- Transcribe speech to text
- Transform voice characteristics (speech-to-speech)
- Generate music from text prompts
- Create sound effects
- Dub audio into different languages
- Extend or inpaint songs
- Build voice assistants or audiobooks

## Available APIs (v7)

### Voice Endpoints
- **Text to Speech**: `POST https://modelslab.com/api/v7/voice/text-to-speech`
- **Speech to Text**: `POST https://modelslab.com/api/v7/voice/speech-to-text`
- **Speech to Speech**: `POST https://modelslab.com/api/v7/voice/speech-to-speech`
- **Music Generation**: `POST https://modelslab.com/api/v7/voice/music-gen`
- **Sound Generation**: `POST https://modelslab.com/api/v7/voice/sound-generation`
- **Create Dubbing**: `POST https://modelslab.com/api/v7/voice/create-dubbing`
- **Song Extender**: `POST https://modelslab.com/api/v7/voice/song-extender`
- **Song Inpaint**: `POST https://modelslab.com/api/v7/voice/song-inpaint`
- **Fetch Result**: `POST https://modelslab.com/api/v7/voice/fetch/{id}`

> **Note**: v6 endpoints (`/api/v6/voice/text_to_speech`, etc.) still work but v7 is the current version. Parameter names have changed in v7 (e.g., `text` is now `prompt`, `audio` is now `init_audio`).

## Discovering Audio Models

```bash
# Search audio/voice models
modelslab models search --feature audio_gen

# Search by provider
modelslab models search --search "eleven"

# Get model details
modelslab models detail --id eleven_multilingual_v2
```

## Audio Model IDs

| model_id | Name | Use With |
|----------|------|----------|
| `eleven_multilingual_v2` | ElevenLabs Multilingual v2 | text-to-speech |
| `eleven_english_sts_v2` | ElevenLabs Voice Changer | speech-to-speech |
| `scribe_v1` | ElevenLabs Scribe | speech-to-text |
| `eleven_sound_effect` | ElevenLabs Sound Effects | sound-generation |
| `music_v1` | ElevenLabs Music | music-gen |
| `inworld-tts-1` | Inworld TTS | text-to-speech |

## Text to Speech

```python
import requests
import time

def text_to_speech(text, api_key, voice_id="21m00Tcm4TlvDq8ikWAM", model_id="eleven_multilingual_v2"):
    """Convert text to speech.

    Args:
        text: The text to convert to speech
        api_key: Your ModelsLab API key
        voice_id: ElevenLabs voice ID (see Available Voices below)
        model_id: TTS model to use
    """
    response = requests.post(
        "https://modelslab.com/api/v7/voice/text-to-speech",
        json={
            "key": api_key,
            "prompt": text,             # v7 uses "prompt" not "text"
            "voice_id": voice_id,
            "model_id": model_id
        }
    )

    data = response.json()

    if data["status"] == "success":
        return data["output"][0]
    elif data["status"] == "processing":
        return poll_audio_result(data["id"], api_key)
    else:
        raise Exception(f"Error: {data.get('message', 'Unknown error')}")

# Usage
audio_url = text_to_speech(
    "Hello! Welcome to ModelsLab. This is a test of our text-to-speech API.",
    "your_api_key"
)
print(f"Audio URL: {audio_url}")
```

## Speech to Text (Transcription)

```python
def speech_to_text(audio_url, api_key, model_id="scribe_v1"):
    """Transcribe speech from audio to text.

    Args:
        audio_url: URL of audio file (must be publicly accessible)
        model_id: STT model to use
    """
    response = requests.post(
        "https://modelslab.com/api/v7/voice/speech-to-text",
        json={
            "key": api_key,
            "init_audio": audio_url,    # v7
