Summary
This study mapped tongue contact areas on artificial palates during speech sounds. Results show distinct tongue-to-teeth contact patterns for different sounds, confined to specific tooth surfaces.
Area of Science:
- Linguistics
- Speech Science
- Dental Phonetics
Context:
- Understanding articulatory phonetics is crucial for speech production research.
- Palatography offers a method to visualize tongue-palate interactions during speech.
Purpose:
- To investigate and map the tongue-to-teeth contact areas for various speech sounds using palatography.
- To analyze and compare the spatial distribution of tongue contact during the pronunciation of specific consonants.
Summary:
- Thirty dentulous adults participated in the study.
- Artificial palates coated with alginate powder were used to record tongue contact during the pronunciation of sounds /sa, fi, çi, ka, ki, ta, na, ra, ja/.
- An image processing system analyzed palatograms, revealing distinct tongue-to-teeth contact areas for each sound, primarily on the incisors and molars.
Impact:
- The findings provide detailed articulatory data for phonetics and speech science.
- This research contributes to a better understanding of the biomechanics of speech production.
- The study highlights the specific lingual-dental interactions during consonant articulation.
