Some notes on syllable structure in articulatory phonology.

Area of Science:

• Linguistics
• Phonetics
• Speech Science

Background:

• Understanding speech sound organization is crucial for phonetics and phonology.
• Previous research has explored gestural coordination in speech production.
• Two main organizational approaches exist: local and global coordination of gestures.

Purpose of the Study:

• To investigate the distinct gestural organization patterns of syllable-initial and syllable-final consonants.
• To determine whether local or global coordination characterizes these consonant positions.
• To explore the implications of these organizational differences for speech perception and phonology.

Main Methods:

• Analysis of articulatory data from American English words.
• Examination of consonant clusters and single consonants in syllable-initial positions.
• Assessment of postvocalic consonants in syllable-final positions.

Main Results:

• Syllable-initial consonants exhibit global organization, forming a 'C-center' coordinated with the vowel gesture.
• Syllable-final consonants demonstrate local organization, with the first postvocalic consonant coordinated to the vowel.
• Distinct organizational strategies are employed for initial versus final consonants.

Conclusions:

• Speech sound organization is context-dependent, utilizing both global and local gestural coordination.
• These findings offer insights into the perceptual and phonological structure of spoken language.
• The study highlights the dynamic nature of articulatory coordination in speech production.
