"L'homme parle ?"
There is absolute no way to tell if this is a question or not by listening to the computer voice. There is little to no intonation in her voice. I got the answer right as the question simply asked me to transcribe the audio, but I had no idea the translation would come out to be "Does the man speak?" I thought it was going to be "The man speaks" or "The man is speaking".
I have to totally agree, whilst I understand that this is a way of asking a question, an indication would have been really helpful
