Overview
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:
- 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?
- Does the combination of parent-implemented BTSR and clinician-led traditional articulation therapy result in generalization of speech sound accuracy at the conversation level?
