Hi @LU-V! I'm Dosu and I’m helping the dify team.

Dify does support Minimax as a TTS provider through its modular provider system, but enabling it requires a few key steps. Make sure the HOSTED_MINIMAX_ENABLED flag is set to true in your configuration, and that you have valid credentials for Minimax in your provider settings. Minimax must also be registered in the provider list, which it is by default in recent versions (source).

The error you’re seeing (IndexError: list index out of range) is likely due to a misconfiguration or missing/incorrect input mapping in your workflow, especially in how user inputs are mapped to the variable pool (source). Double-check that all required variables for TTS are present and correctly mapped.

A few troubleshooting tips:

  • Ensure your workflow is published; TTS features won’t activate until then.
  • If you’re using Firefox, try Chrome or Edge, as browser audio support can differ.
  • Make sure your Minimax TTS model outputs audio in a browser-compatible format (mp3 is safest).
  • If you’re still seeing the error, review your workflow’s input mapping and provider credentials for completeness.

If you need to check the provider setup, look at the HostedMinmaxConfig and init_minimax logic in the codebase (source, source). The TTS system is provider-agnostic, so once Minimax is enabled and configured, it should work like any other TTS provider.

Let me know if you need more details on any of these steps!

After reconfiguring, I found that the TTS model of minimax is supported, but voice cannot be selected
