Speech Recognition Using Articulatory and Excitation Source Features

This book discusses the contribution of articulatory and excitation source information in discriminating sound units. The authors focus on excitation source component of speech — and the dynamics of various articulators during speech production — for enhancement of speech recognition (SR) performance. Speech recognition is analyzed for read, extempore, and conversation modes of speech. Five groups of articulatory features (AFs) are explored for speech recognition, in addition to conventiona...
