Vowel non-vowel based spectral warping and time scale modification for improvement in children’s ASR
, 2021 Acoustic differences between children’s and adults’ speech causes the degradation in the automatic speech recognition system performance when system trained on adults’ speech and tested on children’s speech. The key acoustic mismatch factors are formant,
