This is a tonal language but I am not getting any sound. I get the 'bell' when I put a correct answer but not pronunciation of the words - so far only done 'Man" and 'woman'. I believe this is a beta site, but have you put in the pronunciation yet?
I agree with this being an issue. I am in the first few lessons and there is some pronunciation but not nearly enough. There should be more sound, as well as a better introduction to the alphabet and the sounds of the alphabet. Other sites are helping me much more with those. Duolingo is helping me with vocabulary.
