Cross-language differences in how voice quality and f ₀ contours map to affect.

Area of Science:

• Linguistics
• Psychology
• Acoustic Phonetics

Background:

• Prosody, encompassing voice quality and f0 contour, significantly influences perceived affect.
• Understanding cross-linguistic variations in affect perception is crucial for effective communication.

Purpose of the Study:

• To investigate the interplay of voice quality, f0 contour, and language background in perceived affect.
• To compare how different prosodic features cue affect across speakers of Irish English, Russian, Japanese, and Spanish.

Main Methods:

• Perception tests using synthetic stimuli varying in voice quality and f0 contour.
• Participants rated stimuli on six bipolar scales (e.g., happy-sad).
• Analysis of affect perception across four distinct language groups.

Main Results:

• Non-modal voice qualities, with or without f0 variation, were more effective in signaling affect than f0 variation alone.
• Significant cross-linguistic similarities and divergences in affect perception were observed.
• f0 contour and tense voice played differential roles in affect signaling across languages, notably in Japanese and Spanish versus Irish English and Russian.

Conclusions:

• Voice quality is a critical, often underestimated, component of affective prosody.
• Language background significantly modulates the perception and interpretation of affective cues in speech.
• Affective prosody research must account for both universal and language-specific patterns.
