Creation Methods

There are several options for digital human creation:

1. Use recorded audio as the spoken content for the digital human. (The audio file should contain your voice and the spoken text.) Example:

{
    "audio_url": "https://cdn.gptbest.vip/file/cdn/20250107/RFDQkBGVrHFydzGzzvgXGQmbuPhicK.mp3",
    "avatar_url": "https://cdn.gptbest.vip/file/cdn/20250107/W213dUwMKyxZzXVvW0wUETJZ8KiUDB.mp4"
}

2. Create a voice style and provide read-aloud text and language. (The audio file contains your timbre; no need to speak the exact text.) Example:

{
    "create_voice": {
        "audio_url": "https://example.com/voice.mp3",
        "language": "cn",
        "text": "Hello, I am a digital human!"
    },
    "avatar_url": "https://example.com/avatar.jpg"
}

3. Use a preset voice style and provide read-aloud text and language. Query the default voice list to obtain voice_engine_id and audio_id. Example:

{
    "use_voice": {
        "voice_engine_id": "nina",
        "audio_id": "b92d7e1c40d0447eb563a13ec92d9042",
        "language": "en",
        "text": "Hello, world!"
    },
    "avatar_url": "https://example.com/avatar.mp4"
}
