I don’t feel like any of the voice assistants do a great job of understanding me to start with, so I am guessing translation will be very rough. But then the real challenge - can you translate the music? No, because it translates itself.
Oh boy I can only imagine the responses Alexa will give me when I’m not talking in English. Assistants don’t do a good job understanding me in English anyway (because of accent) let alone any other language
