Newborn swapping, missing, mixing, and illegal adoption is a global challenge and to resolve this emerging issue very less research has been done. Most of the biometric systems are developed for adults and extremely few of them address the difficulty of newborn recognition. As they are the highly non cooperative users of biometrics the ear of newborn may be a perfect source of data for passive identification...
The degradation in the automatic speech recognition performance of the adult speech trained models for children speech data is a well known problem. In this work, motivated by the voice conversion approaches for addressing the acoustic mis-match between the adult and children speech, we investigated the effect of pitch transformation on children speech on telephone-based connected digit recognition...
In this paper, we study the effect of filter bank smoothing on the recognition performance of children's speech. Filter bank smoothing of spectra is done during the computation of the Mel filter bank cepstral coefficients (MFCCs). We study the effect of smoothing both for the case when there is vocal-tract length normalization (VTLN) as well as for the case when there is no VTLN. The results from...
