Differential Cue Weighting in Mandarin Sibilant Production.

Area of Science:

• Phonetics and Phonology
• Speech Communication
• Linguistics

Background:

• Individual talkers exhibit variability in cue utilization for phonological contrast signaling.
• Existing research on cue trading and speech style modulation of this variation is limited and contradictory.

Purpose of the Study:

• To investigate differential cue weighting patterns in Mandarin sibilants.
• To test hypotheses regarding cue trading and individual differences in speech style.

Main Methods:

• Analysis of speech production data from Mandarin speakers.
• Examination of individual differences in the weighting of spectral center of gravity (COG) and the second formant of the following vowel (F2).

Main Results:

• A significant inverse correlation was found between speaker cue weights for COG and F2.
• This demonstrates a cue trading relationship, where speakers rely on one cue more as they rely on the other less.

Conclusions:

• The observed cue weighting patterns in Mandarin sibilants support a cue trading account.
• Individual differences in contrast signaling are explained by how speakers trade off acoustic cues.
