Demo voice cloning no results

Hello All,

trying to test the DEMO Real-Time-Voice-Cloning in the BETA interface

I place a 5-10 second mp3 , type a test sentence, click the “INVOKE” button. Goes through the motions but no “results” is ever generated.
Am probably missing something obvious but have tried several times with a few different mp3 as well as wav files.

Thank You
