Rhythm and convergence between speakers of American and Indian English

The study examines rhythmic convergence between speakers of American and Indian English. Previous research has shown that American English shows tendencies towards stress-timing, and Indian English has been claimed to be syllable-timed (Crystal 1994). Starting from the view that languages differ in their rhythmic tendencies, rather than that they have categorically different rhythmic properties, we examine in an acoustic study the rhythmic tendencies of the two languages, and whether these tendencies can change in the course of an interaction. The focus is on temporal properties (specifically, the duration of stressed syllables and of feet). The results show evidence of mixed rhythmic properties for both languages, with Indian English being more syllable-timed than American English. American speakers show a trend towards changes in foot duration that can be interpreted as accommodation in speech rate or as convergence towards a more syllable-timed foot duration pattern. One Indian English speaker converges in both examined properties towards a more stress-timing pattern. The results are discussed within a dynamical model of rhythmic structure (Saltzman, Nam, Krivokapić, and Goldstein 2008). It is suggested that rhythmic convergence can arise via a tuning between speakers of the prosodic interoscillator coupling function that is proposed in that model. Jelena Krivokapić: Yale University.
