Speech Sound Disorder Clinical Trial
Official title:
Online Assessment and Enhancement of Auditory Perception for Speech Sound Errors: Online Perceptual Training for RSE
The objective of this study is to measure the effects of online perceptual training on perception and production in children with RSE who exhibit atypical perception relative to norms from our lab-based pilot data. In a multiple-baseline across-subjects design, 10 children with RSE will begin in a baseline phase probing perceptual acuity for /r/. Perceptual training with multiple types of stimuli will be initiated in a staggered fashion. Production probes elicited before and after treatment will assess the extent to which perception gains transfer to /r/ production.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Change in percent accuracy pooled across perception tasks | Treatment tasks 2 (identification) and 3 (category goodness judgment) are identical to the tasks used to assess performance in the baseline phase, with the single exception that accuracy feedback is provided during the treatment phase.
Participants' progress will be tracked continuously across baseline and treatment phases using percent accuracy on these two tasks. In Task 2, accuracy in classifying stimuli as /r/ or /w/ will be assessed relative to the mean across responses from typical participants in the research team's lab-based pilot data. In Task 3, accuracy in category goodness judgment will be assessed relative to the "goldstandard" ratings determined by consensus across at least four expert listeners. |
Pre- and within-treatment (up to one month); pre and 1 week post-treatment | |
Secondary | Change in percent accuracy per perception task | Consistent with the primary analysis, participants' progress will be tracked continuously across baseline and treatment phases using percent accuracy; however, percent accuracy scores will be analyzed separately for comparison between tasks (category goodness judgment and identification tasks) using the same analyses as the primary outcome. | Pre- and within-treatment (up to one month); pre- and 1 week post-treatment | |
Secondary | Perceptually rated accuracy of /r/ production | To assess generalization of perceptual training to production, participants will be assessed with standard probes administered in the first three baseline sessions and in three post-treatment maintenance sessions. Probes will elicit 30 words [considered the primary target], 20 syllables, and 10 sentences containing /r/ in various phonetic contexts. Stimuli in each probe will be presented individually in randomized order. No auditory models will be provided; for children with reading difficulty, semantic cues will be provided to elicit the intended word. Individual words will be isolated from the audio record of each word probe and presented in randomized order for binary rating (1=correct; 0=incorrect) by 9 naive listeners who are blind to treatment condition and time point (but will see the written representation of each target word). The research team will use the proportion of "correct" ratings for each token as our measure of perceptually rated accuracy. | Pre- and 1 week post-treatment |
