Details and patient eligibility

About

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.

Enrollment

35 patients

Sex

All

Ages

8 to 50 years old

Volunteers

No Healthy Volunteers

Inclusion criteria

  • Participants must be native English-speaking children with no known hearing or vision deficits. Participants must be within the specified age range and have been identified as having speech production difficulties by a local speech-language therapist.

35 participants in 2 patient groups

Ultrasound plus prosodic cues
Experimental group
Description:
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)
Treatment:
Behavioral: Ultrasound visual feedback
Ultrasound vs Traditional treatment
Experimental group
Description:
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.
Treatment:
Behavioral: Ultrasound visual feedback
