We introduce novel auditory features in the hidden Markov model (HMM) system for detecting child speakers. The features derived by the gammachirp auditory filterbank (GCFB) have been demonstrated to be suitable for vocal tract length (VTL) estimation, both theoretically and experimentally. We performed numerical experiments to distinguish between child and(More)
A n e w digital mul t i -channel audio f o r m a t has been developed for m o t i o n pictures. T h i s f o r m a t has eight original channels and f o u r back-up channels used for error concealment. These channels are divided in to two digital soundtracks suitably so that one of these tracks c a n support the other. T h i s error concealment scheme can(More)
