An interventional study of Visual feedback in Speech Disorders, sponsored by Hospices Civils de Lyon. Completed at 2 sites in France. Open to participants aged 8 Years to 80 Years. Per ClinicalTrials.gov, last updated 2025-09-09.

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.
Exclusion Criteria:
Session of speech therapy conducted with the additional use of articulatory visual feedback based on ultrasound echography, which allows to visualize the patient's tongue in real time on a computer screen
Device: Visual feedback
Session of speech therapy without use of ultrasound echography
Use of ultrasound echography for tongue articulatory visual feedback
BECD test score
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.
Time frame: 4 months
MBLF test score
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.
Time frame: 4 months
Perception test scores
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.
Time frame: 4 months
