There's a note from a user that "Audio is horrendously unclear."
I'm happy that the complaint itself is clear, but I hear both the male and female speaker enunciating Say clearly. It might sound mushy if one were expecting it to sound like English "say" and it is supposed to be little less crisp than English "shy." I think it might just sound unclear to this student because it's a sound in a language you don't know yet.
Any comments from other students on this?
