- Abnormal tongue function and decreased tongue muscles tone can be related to speech difficulties (Am J Speech Lang Pathol. 2019; 28(2); 612).
- Furthermore, the number of tongue movements and the contact points of the tongue with the palate are different in the pronunciation of consonants and words. These can be affected by various tongue malfunctions such as tongue thrust.
- Accordingly, exercising tongue muscles and training the tongue to elevate and rest on the palate is essential for treatment of speech disorders.
