Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Ultrasound plus prosodic cues

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)

Group Type EXPERIMENTAL

Ultrasound visual feedback

Intervention Type BEHAVIORAL

Real-time visual displays of the tongue are used to cue participants to modify the tongue position/shape as they articulate speech sounds

Ultrasound vs Traditional treatment

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.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

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.

Exclusion Criteria

* Participants will be excluded if there is a history of oral structural impairment (e.g., cleft palate), hearing or vision impairment, history of neurological impairment or injury, developmental disabilities such as Down Syndrome or Autism, or intellectual disability.

During initial testing, participants must score below a standard score of 75 on the Goldman-Fristoe Test of Articulation-2 and also score below 20% accurate on a probe list of words assessing accuracy of the /r/ sound
