A study of stress as it relates to computerized speech

For computerized speech to be understood, it must be given human qualities, such as stress. This paper discusses how stress is perceived by the listener, primarily through pitch changes. It shows how inflections stress certain words in a sentence, and that a word's internal stress (accent) affects how these inflections are constructed.An implementation of these findings to add stress to computer speech is shown, compared with similar work, and evaluated.The paper concludes that a word's internal stress must be considered in the generation of speech, and that a grammar in the implementation produces satisfying complex inflections.
