A method of testing a speech transcoder is provided for testing a speech transcoder including at least a speech decoder module connected to a PCM format conversion module where the method of testing includes inputting a standard input vector into an input of the decoder module and outputting a reference vector from the PCM format conversion module. In an alternate embodiment, the method of testing a speech transcoder having a first PCM format conversion module connected to a speech coder module includes inputting a reference vector into the first PCM format conversion module and outputting a new vector from the speech coder that is equivalent to standard speech coder output or equivalent to a vector that was generated by inputting standard speech coder input into a combination of two PCM conversion modules and a reference speech coder.
