Speech Organs | Lingual Movement | Motor Activity | Motor Target | Target Sound Description |
Tongue body | anterior-posterior dimension | Tongue protruding from and retracting into the oral cavity | Establish mobility, stability and equilibrium for independent tongue movement | Basal carriage for all target sounds |
Coronal | inferior-superior dimension | Bending the anterior part of the tongue upward | Encourage control of the tip and blade of the tongue | Lingua-palatal Distortion: /tɕ, tɕʰ, ɕ/ The anterior part of the tongue rises, approaching the palate |
Static state | Biting the tongue tip gently | Enhance tongue tip tension | Blade-alveolar Distortion: /t, tʰ,n, l/ The tip of the tongue touches the alveolar ridge. | |
Clamping the teeth together and holding the tongue behind the the back of the upper teeth to create an obstruction to airflow | Increase tongue tip stability | Apico-dental Distortion: /tsʰ, ts, s/ The tip of the tongue approaches the back of the upper incisor to create an obstruction to airflow | ||
Dorsal | inferior-superior dimension | Elevation of the dorsal surface of the tongue | Facilitate posterior tongue use | Velar Substitution: /k, kʰ/ Discrimination |
