Description

I tried to get a text back from the speech I generated using this model, but the text was a bit of. So maybe having some type of test could help while improving the model.

Basically, "some text" -> speech output -> speech input -> text output -> check if text output is "some text"

Contributor guide

Research direction
Set up an evaluation pipeline that converts text to speech using the TTS model, then transcribes the speech back to text using an STT model, and compares the original and transcribed text to measure fidelity.
