Perceptual grouping is fundamental to many auditory processes. The Iambic-Trochaic Law (ITL) is a default grouping strategy, where rhythmic alternations of duration are perceived iambically (weak-strong), while alternations of intensity are perceived trochaically (strong-weak). Some argue that the ITL is experience dependent. For instance, French…

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)

Recent research in experimental phonetics seems to provide evidence for a clear division between language units and speech units. Many researchers have suggested that the consonant-vowel (CV) syllable may be a universal unit of speech production and perception, while language units become criterial only at higher levels of processing. In second…
