Phonetic cue weighting in perception and production

Area of Science:

• Linguistics
• Psychology
• Speech Perception and Production

Background:

• Speech sound contrasts vary across phonetic dimensions.
• Listeners integrate multiple auditory and external cues during speech perception.
• Comparing cue weighting in speech perception and production informs theories of sound change, learning, and the perception-production interface.

Purpose of the Study:

• To examine the alignment of cue weighting between speech perception and production.
• To explore parallels and asymmetries in cue weighting across modalities.
• To address theoretical, methodological, and analytical differences in quantifying cue weights.

Main Methods:

• Review of existing research on cue weighting in speech perception and production.
• Analysis of how cue weights are conceptualized and quantified across modalities.
• Examination of community and individual level cue weighting.

Main Results:

• Research reveals both similarities and differences (asymmetries) in cue weighting between perception and production.
• Diverse methods for quantifying cue weights reflect inherent modality-specific challenges.
• Existing approaches lack standardization, hindering generalizable findings.

Conclusions:

• Further consideration of analytical metrics and theoretical assumptions is needed.
• Systematic investigation of different cue types will yield more robust findings.
• Improved understanding can inform computational models of speech processing.
