Posture, Tongue Position and Pronunciation

Sponsor: University of Haifa

Summary

Background: The main speech organ that affects the pronunciation of the various vowels is the tongue. The relationships between posture and voice, and between the position of the tongue at rest and posture, have been proven, but the relationship between pronunciation and posture has not yet been proven. The rationale for examining this relationship is that the imbalance and differing loads in poor neck and head posture cause different muscular arrangements of the muscles that support the jaw, tongue, and neck, which will thus affect pronunciation. Objectives: To examine the relationship between posture, tongue position, and the correct pronunciation in subjects with and without pronunciation disorders. In addition, to examine the effect of a muscle strengthening program on these characteristics. Methods: The study will include two parts. The first part will be a cross-sectional study using a questionnaire to examine speech therapists' perceptions of the relationship and importance of posture and pronunciation. The second part will include a prospective interventional clinical study to examine the relationship between tongue position at rest and pronunciation, posture, and muscle strength. In addition, the effect of adding muscle-strengthening training to conventional pronunciation therapy on the process of acquiring correct pronunciation will be examined.
