I tried it and it sounded nothing like me at all - just some random "generic" male voice that translate what I said into german. My wife put it as "that's shit - sounds nothing like you". Nuff said.
I also tried speaking German and translating it to English and when I said "Hallo ich wollte das nur mal ausprobieren" (Hello I just wanted to try this out) it translated it to "Hi, how are you? Do you know anyone who quit smoking?".
I feel gaslit.
