Aging and Spectro-Temporal Integration of Speech

Aging and Spectro-Temporal Integration of Speech

The purpose of this study was to determine the effects of age on the spectro-temporal integration of speech. The hypothesis was that the integration of speech fragments distributed over frequency, time, and ear of presentation is reduced in older listeners-even for those with good audiometric hearing. Younger, middle-aged, and older listeners (10 per group) with good audiometric hearing partici...

Phoneme Classification Using Temporal Tracking of Speech Clusters in Spectro-temporal Domain

This article presents a new feature extraction technique based on the temporal tracking of clusters in spectro-temporal features space. In the proposed method, auditory cortical outputs were clustered. The attributes of speech clusters were extracted as secondary features. However, the shape and position of speech clusters change during the time. The clusters temporally tracked and temporal tra...

Hierarchical Spectro-Temporal Models for Speech Recognition

We seek to explore computational approaches for audition that are inspired by computational visual neuroscience. In particular, we seek to leverage recent progress over the past few years in building a biologically-faithful hierarchical, feed-forward system for visual object recognition [13,14]. The system, which was designed to closely match the currently known feed-forward path in the ventral...
