Can Whisper-JAX also translate audio streams in real time from X -> Y, both of which are non-English languages?

Additionally I have tried Whisper JAX on JupyterHub and for some reason it does not transcribe/translate under 10 seconds for me. In fact, if an audio is 5 minutes long, it would still take 3-4 minutes for transcribing it, although I have followed the similar steps as the ones in the Kaggle notebook, posted by the Author themself. Any ideas/suggestions why this would be happenind would be really helpful.

Thank you!
