I do not know in advance what languages my users will speak.
The main issue remains that the system understands, but instead of returning the transcription, decides to return a translation of that transcription based on the accent of the voice.
Did you test? If you want to test, think Apu from the Simpsons, speaking in english with an accent, he would get a text back in hindi instead of in english… and the hindi text would be the translation of what he said in english.
