Multiresolution elementary tonotopic features for speech perception
Elaine Y L Tsiang · Proceedings of International Conference on Neural Networks (ICNN'97) · 2002
We define multiresolution elementary tonotopic features (ETFs) in general, and present specific functions and decompositions for computing them. Such decompositions, when cast in the form of local, fixed-weight FIR neural networks, have definite architectures. Results of their use as front-end inputs to a speaker-independent continuous-speech phoneme recognizer are encouraging. We analyze the dependence of the recognition performance on the various ETFs at different levels of resolution.
