"Nein, im Bett."
Maybe it has something to do with browsers? I am fully aware of what "Bett" is supposed to sound like, but the audio is off for me. It sounds a little like "Bett" but with a superimposed "s" sound over the "tt" part. I've checked with both Chrome and IE but it sounds garbled with both.
The website is blocked by my work.
This is pretty much what I expect to hear:
What I hear with Duo is the "im" and "Bett" seem to be pronounced quickly and as one word (like she was only given 2.5 seconds of tape to record on, and after 2.0 seconds she realized she wasted too much time on "Nein," and then tried to squeeze "im Bett" into the 0.5 seconds she had left). The m and B are mildly overlapping, and a distinct s or z sound over the tt.
I'll give your link a listen after work though and let you know what I hear.
@ wataya So I'm special?! ;-)
