Linda, Certainly, there's going to be a sound quality issue if you're mostly using the BP for Human recorded material, and comparing that with synthesized speech. Having said that, I'm personally not crazy about the doubletalk synth chip, but find I can easily understand it. I've not used the BRF file format for the BP... instead using the DT book file format when sending a Bookshare book file to the BP. Can you be a bit more specific with the sound symptoms you're experiencing? --Barry
