Description
Inclusion Criteria:
- Must be between 9;0 and 15;11 years of age at the time of enrollment.

- Must speak a rhotic dialect of English.
- Must pass a pure-tone hearing screening at 20dB HL
- Must pass a brief examination of oral structure and function.
- Must exhibit less than 30% accuracy, based on consensus across 2 trained listeners, on a probe list eliciting rhotics in various phonetic contexts at the word level.
- Must exhibit no more than 3 sounds other than /r/ in error on the GFTA-3
Exclusion Criteria:
- Must not receive a T score more than 1.3 SD below the mean on the Wechsler Abbreviated Scale of Intelligence-2 (WASI-2) Matrix Reasoning
- Must not receive a scaled score of 7 or higher on the Recalling Sentences and Formulated Sentences subtests of the Clinical Evaluation of Language Fundamentals-5 (CELF-5).

Intervention / Treatment |
---|---|
Experimental: Online Speech Training
Participants will be randomly assigned to transition from the baseline to the treatment condition at one of 7 possible points, ranging from 4 to 10 baseline sessions. All participants will receive 12 sessions of perceptual training over 4 weeks. Finally, participants will complete a 3-session maintenance phase in which perception and production are probed but not treated. Perception will be measured using the identification and category goodness judgment. Following completion of perception training all participants will complete two weeks of production training. The production training will consists of 4, 60-minute sessions. Each session will provide instruction and practice trials. |
Perceptual training involves self-paced presentation of auditory stimuli via a computerized software program. Stimuli are organized into three separate tasks: Tasks 1 and 3 will train category goodness judgment: Participants will hear 75 naturally produced speech tokens containing /r/ from various speakers, with a balance of correct and incorrect productions. They will classify each /r/ as correct or incorrect and receive feedback on the accuracy of their classification. Tasks 1 and 3 differ in that task 1 will feature a subset of items designed to provide focused practice on a specific context (e.g., initial /r/ as in red; /r/ as syllable nucleus as in sir), with increasing difficulty over time, whereas task 3 will feature randomly selected items representing all contexts and difficulty levels. Task 2: Participants will hear 75 items drawn from the synthetic rake-wake continuum used in the identification task administered at baseline. Instruction: Discuss tongue shapes for /r/. Pre-practice: relatively unstructured, highly interactive elicitation; provide models and placement cue and KP on every trial. Structured syllable practice: Practice will occur in blocks of 10 consecutive trials on the same syllable (e.g., 10 /ra/), after which a new syllable will be addressed (e.g., 10 /re/--but note that in the fully blocked condition, the same syllable should occur in two consecutive blocks of 10). |
What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in percent accuracy pooled across perception tasks
Time Frame: Pre- and within-treatment (up to one month); pre and 1 week post-treatment
|
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 Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in percent accuracy per perception task
Time Frame: Pre- and within-treatment (up to one month); pre- and 1 week post-treatment
|
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
|
Perceptually rated accuracy of /r/ production
Time Frame: Pre- and 1 week post-treatment
|
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.
