The influence of varying vowel phonation and duration on rhythmic grouping biases among Spanish and English speakers

This study is the first to establish that creak is perceptually salient for Spanish speakers and to demonstrate that the percept associated with duration can differ depending on whether it is varied singly or together with creak. More generally, the current findings show that grouping effects extend beyond intensity, pitch and duration, the features most often manipulated in rhythmic grouping studies inspired by the Iambic-Trochaic Law.
