Acoustic/Linguistic Aspects of Automatic Speech Recognition.

Abstract

This report describes: (1) Acquisition of a carefully labeled and segmented data base of connected speech for the testing of segmentation and phonetic identification algorithms. (2) Development and testing against the data base of a segmentation algorithm based on rate of spectral change and rms energy (3) Initiation of a study of inter-speaker vowel-format scaling based on a 2-dimensional constraint on a speaker's first three formant frequencies.
