Maybe one of the APH technical folks can comment on this one. I'm temporarily using another BP unit that seems to be considerably older than mine and I swear that there's a significant difference in the speech, despite its having the same firmware on it. Over the life of the BP, have there been changes in the Doubletalk voice synthesis? I'm finding the temporary unit much harder to understand--especially on glottal sounds--than the one I'm used to. -- Walt Smith - Clearwater, FL walt@xxxxxxxxxx
