Two experiments investigated the way acoustic markers of prominence influence the grouping of speech sequences by adults and 7-month-old infants. In the first experiment, adults were familiarized with and asked to memorize sequences of adjacent syllables that alternated in either pitch or duration. During the test phase, participants heard pairs…

Outlines an approach for studying auditory levels in speech perception, focusing on the artificial speech understanding system that is most compatible with the experimental data obtained in speech perception research. (RL)

Explored the extent to which a model of the acoustic consequences of overlapping, sliding consonantal and vocalic gestures was used to account for stress-induced changes in F2 trajectories occurring in test words embedded in a carrier phrase. Three stress conditions were studied including contrastive stress on test words, contrastive stress on the…

Previous works in English have revealed that disfluencies follow regular patterns and that incorporating them into the language model of a speech recognizer leads to lower perplexities and sometimes to a better performance. Although work on disfluency modeling has been applied outside the English community (e.g., in Japanese), as far as we know…
