Outcome Measures

Primary Outcomes (1)

Change in percent correct for treated sound, rated by blinded listeners.
To assess generalization of treatment gains to untreated words, participants will read a 200-word probe list eliciting the treated sound (/ɹ/ or /s/). 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 (correct/incorrect) by listeners who are blind to treatment condition and time point (but will see the written representation of each target word). We will use the change in percent correct as our primary measure of perceptually rated accuracy.
Before the initiation of treatment and again 10 weeks later.

Secondary Outcomes (2)

Proportion of responders and non-responders in each group.
10 weeks after the start of treatment.
Survey evaluating impacts of speech disorder on participants' social, emotional, and academic well-being.
Before the initiation of treatment and again 10 weeks later.

Study Arms (2)

Intensive Treatment

EXPERIMENTAL

Speech Motor Chaining will be delivered in an intensive fashion. Week 1: 8 sessions (2 sessions per day on 4 different days) Week 2: 3 sessions (1 per day on 3 different days) Week 3: 3 sessions (1 per day on 3 different days) Week 4: 2 sessions (1 per day on 2 different days)

Behavioral: Speech Motor Chaining

Distributed Treatment

EXPERIMENTAL

Speech Motor Chaining will be delivered twice weekly for 8 weeks

Interventions

Speech Motor ChainingBehavioral

Sessions begin with Pre-practice to elicit target sounds, with verbal cueing and shaping strategies. During Structured Practice, items are practice in blocks of 6 consecutive trials (with systematic increases in difficulty), and our web-based software will manipulate the principles of motor learning, including the stimulus prompt, the participant's production, analysis of the clinician's rating, feedback prompts for the clinician, and the variability present in the practice trial. Randomized Practice will also be guided by the software and includes all linguistic levels that were produced correctly during Structured Practice, with items presented in random order.

Masking Details

All perceptual ratings will be obtained from raters who are blinded to treatment group and to timepoint. Binary rating responses will be obtained from three listeners per token.

TREATMENT

Intervention Model

PARALLEL

Model Details: Participants will be randomized across two conditions, Distributed and Intensive (1:1 ratio). All participants will complete a Dynamic Assessment (DA) session consisting of 40-minutes of instruction and feedback on how to produce the /ɹ/ or /s/ sound. Following the DA session, participants will imitate 45 syllables containing the /ɹ/ or /s/ sound, and based on their performance, will be classified as High Stimulability or Low Stimulability. Participants will be stratified randomized to receive 16, 50-minute speech sessions in Intensive Treatment or Distributed Treatment.
