Programmable AI tutor app with audio Q & A?

Looking to acquire an AI app that will enable me as instructor to enter audio content (potentiasl answer clips) that can be combined or extrapolated upon based on my perameters to give audio answers to students. No testing or aids, just pure Q & A dialouge. Any suggestions?

If I understand this correctly you want to message your students audio messages (in your own voice?) but these messages should be synthesized based on a configuration that you apply for each message (type or student).

This implies the need for a language model that will write the messages and then create the audio file to send to your chat with the students.

And chat app connected with the LLM that will send requests to the audio generation function based on a more or less sophisticated set of pre-written “base answers”?

Not sure, if this exists already but it can be build.
