    ## About VEVO
    VEVO is a versatile voice synthesis and conversion model that offers four main functionalities:
    1. **Vevo-Style**: Maintains timbre but transfers style (accent, emotion, etc.)
    2. **Vevo-Timbre**: Maintains style but transfers timbre
    3. **Vevo-Voice**: Transfers both style and timbre with separate references
    4. **Vevo-TTS**: Text-to-speech with separate style and timbre references
