Computer Algorithms for the Extraction and Application of Stress Contours from Continuous Speech Sentences,

摘要

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 phoneme's formant structure, (2) Word boundary detection, and (3) A partial estimate of a passage's syntactic structure.
