A MAP Based Approach to Adaptive Speech Intelligibility Measurements

This paper presents an adaptive procedure applied to measurements of speech intelligibility using the modified rhyme test. It is argued that the required speech-to-noise (SNR) ratio could be estimated with sufficient accuracy with as few as 25 utterances. The present procedure is based on the maximum a posteriori criterion, and it is demonstrated how the standard deviation of the SNR estimate can be improved by about 0.5 dB compared to a previously published method based on the maximum likelihood procedure.
