Ultrasound Biofeedback for Speech Sound Disorders

This study is currently recruiting participants. (see Contacts and Locations)

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.

Condition Intervention Phase
Speech Sound Disorders
Behavioral: Ultrasound visual feedback

Study Design: Allocation: Non-Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Biofeedback and Speech Disorders

Primary Outcome Measures:
  • Percent correct for target speech sound [ Time Frame: Change in accuracy after 7 one-hour treatment sessions (3.5 weeks), and after 14 one-hour treatment sessions (7 weeks) ] [ Designated as safety issue: No ]

Estimated Enrollment: 16
Study Start Date: May 2013
Estimated Primary Completion Date: May 2016 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 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)
Behavioral: Ultrasound visual feedback
Real-time visual displays of the tongue are used to cue participants to modify the tongue position/shape as they articulate speech sounds
Experimental: 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.
Behavioral: Ultrasound visual feedback
Real-time visual displays of the tongue are used to cue participants to modify the tongue position/shape as they articulate speech sounds


Ages Eligible for Study:   8 Years to 50 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

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
