Summary
This study reveals how Mandarin speakers use pitch (F0) to signal both questions and focus, finding these functions are processed in parallel. Listeners can detect both question and focus intonation simultaneously.
Area of Science:
- Linguistics
- Phonetics
- Psycholinguistics
Background:
- Disagreements persist regarding question intonation across languages.
- Previous research often overlooks the significant role of focus in intonation.
Purpose of the Study:
- Investigate question intonation in Mandarin, incorporating the function of focus.
- Analyze how focus affects pitch contours in various question types.
- Determine if listeners can simultaneously perceive focus and question intonation.
Main Methods:
- Experiment 1: Native Mandarin speakers produced statements and various question types with controlled focus.
- Detailed F0 contour analysis to examine pitch modifications.
- Experiment 2: Listener perception tests to assess the detection of focus and question intonation.
Main Results:
- Focus expands pitch range on focused words and suppresses post-focus pitch, similar to statements.
- Subtracting statement F0 from question F0 revealed exponential difference curves.
- An interaction between focus and question meaning was observed, boosting pitch raising from the focused word.
- Listeners generally detected both focus and question intonation simultaneously.
- Lowest identification rates occurred with neutral focus in questions and final focus in statements due to competing F0 adjustments.
Conclusions:
- Mandarin question intonation is shaped by both interrogative meaning and focus.
- Focus and question functions are encoded in parallel and can be simultaneously transmitted.
- Competing F0 adjustments at the sentence-final position can lead to perception confusions.
