An interventional study of Adaptive recursive self-feedback procedure and Non-adaptive recursive self-feedback procedure in Aphasia and Stroke, sponsored by University of South Florida. Recruiting at 1 site in United States. Open to participants aged 18 Years to 80 Years. Per ClinicalTrials.gov, last updated 2026-09-14.
Sponsored by University of South Florida · Not applicable, Interventional, and Treatment
The goal of this clinical trial is to test the effects of recursive self-feedback procedures on spontaneous speech production in stroke survivors with impaired speech production (aphasia). The main question it aims to answer is:
Participants will be engaged in the following activities:
338 studies on the registry are indexed under Aphasia; 95 are open to participants now.
This study's planned enrollment of 45 is above the median of 30 across 298 interventional studies indexed under Aphasia.

Exclusion Criteria:
Using a tablet, participants listen to speech playback of their response to a prompt and self-correct/minimize their speech errors in a subsequent attempt. This process is looped multiple times per prompt. It adapts across narrative prompts with low and high complexities.
Behavioral: Adaptive recursive self-feedback procedure
Using a tablet, participants listen to speech playback of their response to a prompt and self-correct/minimize their speech errors in a subsequent attempt. This process is looped multiple times per prompt. However, it only uses narrative prompts with high complexity.
Behavioral: Non-adaptive recursive self-feedback procedure
The intervention uses self-feedback alone to improve speech production. It adapts the complexity of the treatment tasks.
The intervention uses self-feedback alone to improve speech production. However, it does not adapt the complexity of the treatment tasks.
