Identification of acoustically modified Mandarin tones by non-native listeners

Area of Science:

• Phonetics and Phonology
• Second Language Acquisition
• Auditory Perception

Background:

• Mandarin Chinese is a tonal language where pitch contours distinguish word meaning.
• Non-native listeners often struggle with accurate Mandarin tone identification.
• Understanding how acoustic modifications affect tone perception is crucial for language pedagogy.

Purpose of the Study:

• To investigate how non-native Mandarin listeners identify fragmented tones.
• To examine the impact of syllable modifications and carrier phrase context on tone perception.
• To analyze tone confusion patterns and reaction times in Mandarin tone identification.

Main Methods:

• Digitally manipulated Mandarin syllables (intact, silent-center, center-only, onset-only) were created.
• Syllables were embedded in carrier phrases with continuous or discontinuous fundamental frequency (F0).
• Response accuracy, reaction time, and tone confusion matrices were analyzed.

Main Results:

• Intact and center-only syllables yielded higher identification accuracy than silent-center and onset-only.
• Mandarin Tone 2 was consistently the most difficult tone for non-native listeners.
• Fundamental frequency (F0) continuity between carrier and target tones significantly impacted identification.

Conclusions:

• Syllable integrity and F0 continuity are key factors in non-native Mandarin tone identification.
• Non-native listeners may not fully utilize coarticulatory cues for tone perception.
• Acoustic context plays a significant role in overcoming challenges in recognizing Mandarin tones.
