1. Is this request related to a challenge you're experiencing? Tell me about your story.

The current text-to-speech generation feature, whether using the "audio" tool in the workflow or directly calling the "text-to-speech" function, cannot customize the voice after the workflow is published. However, in dialogue workflows, it is often necessary to use different voice lines based on different personas of intelligent agents, so the "voice" parameter needs to be passed as an argument for each call. This also allows models with voice cloning capabilities to dynamically pass voice URL links to generate custom voices.

2. Additional context or comments

3. Can you help us with this feature?

Hi, @FeyaM. I'm Dosu, and I'm helping the Dify team manage their backlog and am marking this issue as stale.

Issue Summary:

  • You requested the ability to customize the "voice" parameter dynamically in the "Audio" utilities' text-to-speech feature.
  • This would allow different voices for intelligent agent personas and support dynamic voice cloning via URLs after workflow publication.
  • Currently, voice customization is fixed once a workflow is published, limiting flexibility.
  • There has been no further activity or comments on this issue since it was opened.
  • The issue remains unresolved.

Next Steps:

  • Please let me know if this feature request is still relevant to the latest version of Dify by commenting on this issue.
  • If I do not hear back within 15 days, I will automatically close the issue.

Thank you for your understanding and contribution!
