Performance Comparison Of Intrusive Objective Speech Intelligibility And Quality Metrics For Cochlear Implant Users

摘要
In this paper, we evaluate the performance of six intrusive objective measures as intelligibility predictors of degraded speech for cochlear implant (CI) users. Three practical environmental degradation scenarios are considered: reverberation alone, additive noise alone, and noise-plus-reverberation. A subjective intelligibility test was performed with eleven cochlear implant users and objective measures were evaluated using four performance metrics: Pearson, Spearman rank, and sigmoid-fitted correlation coefficients, and the root mean square error. It was observed that existing metrics performed well in the noise-alone scenarios, but obtained lower performance in the reverberation-alone scenario and in many cases, unacceptable results in the noise-plus-reverberation scenario. It is concluded that further work is still needed in order to accurately predict speech intelligibility ratings for CI users, particularly in environments corrupted by reverberation.
