Computer Algorithms for the Extraction and Application of Stress Contours from Continuous Speech Sentences,
PURDUE UNIV LAFAYETTE IND SCHOOL OF ELECTRICAL ENGINEERING
Pagination or Media Count:
Past research in speech recognition has emphasized the need to apply prosodic feature information when making decisions at the phonetic and lexical levels. Of particular interest has been a means by which the stress contour of a continuous speech sentence could be obtained without first performing phonetic recognition. The availability of such stress information permitted 1 More accurate vowel recognition by determining beforehand the reliability of a phonemes formant structure, 2 Word boundary detection, and 3 A partial estimate of a passages syntactic structure.
