Phase 1

Completed

• Conditions: Speech Sound Disorders
• Interventions: Behavioral: Ultrasound visual feedback

• Registration Number: NCT01905449
• Lead Sponsor: Yale University

Brief Summary

Children with speech sound disorders will receive speech therapy using real-time images of the tongue from ultrasound. These images will be used to cue the child to change the tongue position when producing speech sounds.

Arm && Interventions

Group	Intervention	Description
Ultrasound plus prosodic cues	Ultrasound visual feedback	One sound in error is treated with ultrasound visual feedback while also cueing prosodic variation (7 one-hour sessions). Another sound in error is treated with the ultrasound visual feedback with no prosodic variation (7 one-hour sessions). Prosodic variations are cues to coordinate production of the target sound with intonation patterns such as questions (rising intonations), commands (loud/emphatic), or statements (neutral)
Ultrasound vs Traditional treatment	Ultrasound visual feedback	One sound in errors is treated with ultrasound visual feedback for approximately half of each session and traditional treatment for half of the session (7 one-hour sessions). Another sound in error is treated with no ultrasound visual feedback, using traditional treatment for the entire session (7 one-hour sessions). These traditional cues include verbal instructions on how to move the tongue to achieve a particular speech sound.

Primary Outcome Measures

Name	Time	Method
Percent correct for target speech sound	Change in accuracy after 7 one-hour treatment sessions (3.5 weeks), and after 14 one-hour treatment sessions (7 weeks)
