Hey @loretoparisi thanks for opening this, unfortunately I am not able to reproduce this I used the code and example found here: https://github.com/ajredniwja/transcribe-example.

Is it possible for you to share code and the file?

In the original code they mention they use a RAW PCM file, and you used a WAV, so I think the problem is likely there.
