what is the difference between speech API and sound API ?? I am gona make a voice chat application. Which API i should use for voice capturing, storing and then streaming ??

From what I can tell, the speech API seems more focused on higher-level computer synthesized voices (kind of like you get on some GPS's) and voice recognition. Since you just want a voice chat application, it doesn't matter what the computer thinks of the data, it just needs to pass it. Sound API is much better suited for this purpose.
