Abstract
The authors propose a low cost 6 kbps multipulse-excited linear prediction coder for 8 kbps transmissions on 12.5 kHz radio channels. The main purpose of this system is to give good intelligibility and good speaker recognition. Against transmission errors, the authors present a correcting strategy and an extrapolation method that hides lost speech frames
