Summary
Tongue tip speed during speech is faster for voiceless alveolar consonants than voiced ones. Movement distance, not vowel stress, primarily influences tongue tip speed for these sounds.
Area of Science:
- Linguistics
- Phonetics
- Speech Science
Background:
- Understanding articulatory dynamics is crucial for speech production models.
- Previous studies show differences in articulatory movements between voiced and voiceless consonants.
Purpose of the Study:
- To investigate the kinematic properties of tongue apex movements for American English alveolar consonants.
- To determine the influence of consonant voicing and vowel stress on tongue tip speed.
Main Methods:
- Lateral cineradiography at 100 frames per second.
- Analysis of tongue apex movements in five American English speakers.
- Measurement of tongue tip speed and displacement during consonant production.
Main Results:
- Tongue apex moved faster towards voiceless alveolar stops than voiced alveolar stops.
- No significant difference in tongue speed between voiced alveolar stops and alveolar taps.
- Faster speeds for taps were correlated with greater movement distances.
- Vowel stress did not independently affect tongue tip speed towards alveolar consonants.
Conclusions:
- Tongue tip speed is influenced by consonant voicing and movement distance.
- Articulatory distance is a key factor in determining tongue tip kinematics.
- Vowel stress is not a primary determinant of tongue tip speed in this context.
