Perceptually informed quantification of speech rhythm in pairwise variability indices.

Two previous experiments demonstrated that f0 and duration are interdependent in the perception of rhythmic groups in speech and sentence rhythmicality, and that the relative weighting of tonal and durational cues depends on listeners' native language. The listeners were native speakers of Swiss German, Swiss French, or Metropolitan French (i.e.

The language- specific interdependence of tonal and durational cues in perceived rhythmicality.

This experiment investigated whether fundamental frequency (f0) and duration are interdependent cues for the perceived rhythmicality of sentences, and whether this depends on the native language of listeners. The task required a judgement of which stimulus sentence had the most natural- sounding rhythm. In the stimuli, duration and f0 were manipulated on a certain syllable to test whether a deviant duration results in a less natural- sounding rhythm than a deviant f0 movement, or vice versa.

The interdependence of tonal and durational cues in the perception of rhythmic groups.

This experiment investigated whether rising fundamental frequency (f0) and increased duration are interdependent perceptual cues to rhythmic groups in speech, and whether this depends on listeners' native language. In a two-alternative forced- choice decision task, listeners had to indicate whether they perceived a 3 + 2 or 2 + 3 grouping in 5- syllable- long series of various digits and letters, in which f0 and duration were manipulated in the second and/or third syllable. The listeners were native speakers of Swiss German, Swiss French, or French.
