Best Practices

  1. Voice Selection

    • Choose appropriate voices for your use case
    • Consider using voice cloning for custom voices
    • Test different voices for optimal results

  2. Performance

    • Use streaming for real-time applications
    • Consider async API for longer texts
    • Cache frequently used audio

  3. Error Handling

    • Implement proper error handling
    • Monitor API rate limits
    • Handle network issues gracefully

If you clone a voice in one language and then use that cloned voice to generate speech in a different language, the output will be highly unreliable. For best results, ensure that the voice you use to generate speech matches the language of the text you want to generate speech for.
