Improving children s mismatched asr through adaptive pitch compensation

Abstract

With the progress made in the speech processing over the last few decades an increasing number of user applications employing automatic speech recognition ASR systems are being developed In such human machine interaction HMI applications the ASR system is often accessed by both the adults and the children It is well known that the ASR systems trained on the adults speech exhibit a severely degraded recognition performance when used for transcribing the speech data from the child speaker
