Hello Ala,
You can check that by the length of an encoded frame.
In WB mode I check if it's below 10 bytes then I known that the DTX has
recognized that frame as unvoiced.

Betreff: [Speex-dev] frame perceptual classification in Speex

Hello everyone,
I wonder if Speex classifies the frames into Voiced/Unvoiced frames like the
G.729 codecs. If yes, how we can know the voiced/unvoiced frames?
