GSM-FR is a Full Rate speech coder standardized by the European Telecommunications Standards Institute (ETSI) for compressing toll quality speech (8000 samples / second). The coder has a bit rate of 13 kbps.

This coder uses the principle of Regular Pulse Excitation-Long Term Prediction-Linear Predictive coding.

The coder works on a frame of 160 speech samples (20 msec), and no look ahead is required. So the algorithmic delay for the coder is 20 msec.

Currently Encore’s G.711 is available on TI’s TMS320C64x (c64x), TMS320C62x (c62x) platforms.
