Addressing pitch mismatch for children s automatic speech recognition

Abstract

This thesis addresses the acoustic mismatch due to pitch differences between the adults and the children s speech for children s automatic speech recognition ASR on adult s speech trained models The motivation for the work is obtained through the study done on exploring various acoustic sources of mismatch pitch speaking rate formant frequencies and glottal flow parameters open quotient return quotient and speed quotient for children s ASR on adults speech trained models The effect o
