The subjective speech-to-noise-ratio (SNR), derived from the forced-choice pair-comparison test using the psychometric analysis procedure, has well represented overall speech quality of speech coders in a single dimension. No significant speaker and listener variation has been found for a wide range of waveform coders at the tests conducted in two separate sessions 14 months apart using different groups of English speakers and listeners. The purpose of this study is to investigate reproducibility of the measure conducting the same framework test using Japanese speakers and listeners. The test result shows the subjective SNR measure gives quite reliable scores evaluated in different laboratories with different language backgrounds.
