Vocoder Mean Opinion Score Conformance Test [ANSI/TIA/EIA-102.BABB]

This document specifies the procedures to be used to test that implementations of TIA-102.BABA compatible speech codecs comply with the standard. This speech codec is the Improved Multi-Band Excitation (IMBE--trade mark of Digital Voice Systems, Inc.) system described in TIA-102.BABA, "Project 25 Vocoder Description." This standard takes the approach of defining a reference speech codec and then each manufacturer tests his imlementation relative to the reference. The IMBE speech codec is used to digitally encode the speech signal and provide forward error control for thransmission at a data rate of 7200 b/s.
Other Standards: This document specifies the procedures to be used to test that implementations of TIA-102.BABA compatible speech codecs comply with the standard.
