Visual Feedback of Tongue by Ultrasound Echography for Speech Trouble Rehabilitation

Speech is a privileged means of communication for humans: its trouble can thus prove being extremely handicapping. Standard speech therapy is limited in some cases by the lack of sensory feedback available to the patient (hearing, surgery, neural damage, etc.).

The present study aims at quantify the contribution of the tongue articulatory visual feedback offered by ultrasound echography to speech trouble rehabilitation.

Two complementary populations will be studied : 30 adults with buccopharyngeal surgery, and 10 childrens with important speech troubles due to central nervous system damage.

The principle is to conduct standard speech therapy sessions, alternating series of sessions with the use of visual feedback and sessions without visual feedback.

The progress will be regularly measured by means of standard batteries of speech articulation tests.

Device

Use of ultrasound echography for tongue articulatory visual feedback

Primary outcomes

BECD test score

Time frame: 4 months

One of the primary outcome will be measured as the difference of increase of total BECD score between the therapy sessions with and without visual feedback.

BECD ("Batterie d'Evaluation Clinique de la Dysarthrie, Battery of Clinical Evaluation of Dysarthria") is a French speech articulation test.
MBLF test score

Time frame: 4 months

The second primary outcome will be measured as the difference of increase of total MBLF score between the therapy sessions with and without visual feedback.

MBLF ("Motricité Bucco-Linguo-Faciale, Motricity of Mouth, Tongue and Face") is a French speech articulation test.

Secondary outcomes

Perception test scores

Time frame: 4 months

The secondary outcome will be measured as the difference of increase of the scores of perception obtained by a jury listening to a selected set of patients' speech sounds between the therapy sessions with and without visual feedback. The speech sounds are those recorded during the batteries of speech articulation tests.
