About this trial
Using a single-case multiple baseline across participants design, this study aims to explore the effectiveness of parent-implemented Broad Treatment Speech Recast supplemented with traditional clinician-led articulation therapy on speech production in elementary-aged deaf and hard of hearing children.
To address these objectives, the following research questions will be investigated:
1. Does drill-based articulation therapy, administered by a speech-language pathologist, improve speech sound production in DHH children when parent-implemented BTSR is concurrently utilized at home? 2. Does the combination of parent-implemented BTSR and clinician-led traditional articulation therapy result in generalization of speech sound accuracy at the conversation level?

Broad Target Speech Recast
BehavioralBroad Target Speech Recasts (BTSR) is a speech intervention technique in which an adult immediately recasts a child's incorrect articulation by providing a corrected version of the word in a naturalistic, meaningful context. Unlike traditional articulation therapy, which focuses on isolated sound drills, BTSR integrates correction seamlessly into conversation without requiring the child to repeat or imitate the model. This approach is rooted in principles of implicit learning, where repeated exposure to accurate speech models facilitates phonological development over time. BTSR differs from traditional minimal pair or phonetic placement techniques in that it does not involve explicit instruction or direct prompts for self-correction. Instead, it provides high-frequency, naturalistic exposure to correct phoneme production within functional language use.
Traditional Speech Therapy
BehavioralTraditional Speech Therapy is clinician-led and includes structured, drill-based approaches. Techniques such as placement cues, direct feedback, and reinforcement are used to help children achieve correct articulation. The structured nature of this approach is often more effective in remediating persistent speech errors than parent-implemented strategies alone. This study examines whether the combination of parent-implemented BTSR and clinician-led traditional articulation therapy leads to improved speech sound production and long-term maintenance of correct articulation in elementary-aged DHH children.
Treatment groups
Trial outcomes
Primary outcomes
Target phoneme production accuracy
The percent of accurate phoneme productions per target, which is derived by dividing the number of correct productions by the total possible points for each target and then multiplying by 100. Accurate phoneme production is defined by a speech-language pathologist's judgment of perceptual accuracy through the lens of broad transcription.
Secondary outcomes
Goldman Fristoe Test of Articulation - Third Edition (GFTA-3)
The Goldman-Fristoe Test of Articulation, Third Edition (GFTA-3) is a standardized assessment used to evaluate speech sound production in children, adolescents, and young adults (ages 2;0-21;11). It measures articulation skills by assessing a child's ability to produce consonant sounds in different word positions (initial, medial, final) and in connected speech. The test provides standard scores, percentile ranks, and age-equivalent scores. Scores are standardized with a mean of 100 and a standard deviation of 15. Standard scores range from 40 to 160, with higher scores indicating better articulation abilities.
Generalization to Conversation
Connected speech samples will involve a ten-minute conversation or play-based dialog initiated by the examiner or parent to elicit natural speech from the child. Various techniques may be employed to encourage a sample abundant in expressive language, including the use of open-ended questions and engagement in child-led pretend play. This task will occur at three time-points throughout the study (baseline, BTSR phase, after intervention criteria has been reached) to measure generalization, and it should be administered after the listening check and before the probe. This task will be captured on video for later analysis. Accuracy of phoneme targets will be calculated using percent of consonants correct.
