System development that focuses on speech intelligibility

Purpose of Research

Speech intelligibility estimation method from few samples in noisy conditions

Summary of Research

Assessment of speech intelligibility under noisy conditions requires experimental subjects to listen to and evaluate many sounds. Thus, the burden on subjects is significant, and carrying out large-scale experiments is not easy. For lowering evaluation costs, the number of words on intelligibility evaluation word lists need to be reduced. By using binomial distribution to express intelligibility, conducting experiments with one word per condition is possible for all words whose likelihood of cognition is the same. In this paper, we proposed an estimate method from results of subjective evaluation using only 20 words. The ability of estimator to predict subjective assessment values resulted in the root mean squared error of 0.068 on the overall condition average.
