Duration-based auditory grouping preferences are presumably shaped by language experience in adults and infants, unlike intensity-based grouping that is governed by a universal bias of a loud-soft preference. It has been proposed that duration-based rhythmic grouping preferences develop as a function of native language phrasal prosody.…

Speech utterances are more than the linear concatenation of individual phonemes or words. They are organized by prosodic structures comprising phonological units of different sizes (e.g., syllable, foot, word, and phrase) and the prominence relations among them. As the linguistic structure of spoken languages, prosody serves an important function…

Research is reported in which subjects were required to perceive sentences in noise. A series of sentences having the same syntax and rhythm was presented. On a final sentence either rhythm alone or rhythm plus syntax were changed. The results stress the importance of rhythm in speech perception. (Author/RM)
