European Digital Cellular Telecommunications System; Half Rate Speech Part 8: Test Sequences for the GSM Half Rate Speech Codec (GSM 06.07 Version 4.0.1)
This European Telecommunication Standard (ETS) part 8 specifies the digital test sequences for the GSM half rate speech codec. These sequences test for a bit exact implementation of the half rate speech transcoder (GSM 06.20 (ETS 300 581-2) [2])@ Voice Activity Detection (GSM 06.42 (ETS 300 581-6) [6])@ comfort noise (GSM 06.22 (ETS 300 581-4) [4]) and the discontinuous transmission (GSM 06.41 (ETS 300 581-5) [5]).
