ABSTRACT:
The invention provides an improved method and apparatus for identifying a bad GSM speech frame. Both the estimated signal-to-noise ratio (ESNR) of the received signal and the pseudo bit error rate (PBER) of a recorded speech signal are used to determine whether or not a speech frame is bad.
