| Abstract(in English) | Primates and mammalian distinguish overlapped speech sounds from one another by recognizing a single sound source whether temporal contour of auditory speech features in auditory neurons are similar.This is called as temporal synchronization detection and clustering function. The performance of this detection and clustering function depends on the former function that is auditory speech feature extraction. The feature extraction is needed to satisfy two requirements: 1) auditory speech features are mutually stochastic independent and 2) the feature extraction should allow various complicated sounds to be represented, which leads to non-linearity.This paper introduces non-linear sparse encoder decoder model as computational model, implements it with a ladder network, and finally evaluate that network behavior. We show that our trained network can output auditory speech features that are mutually stochastic independent. |
