Interventions

  • Adaptive recursive self-feedback procedure — BEHAVIORAL
    The intervention uses self-feedback alone to improve speech production. It adapts the complexity of the treatment tasks.
  • Non-adaptive recursive self-feedback procedure — BEHAVIORAL
    The intervention uses self-feedback alone to improve speech production. However, it does not adapt the complexity of the treatment tasks.

Study Details

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: • To what extent can stroke survivors with aphasia use their self-feedback alone to improve their spontaneous speech production? Participants will be engaged in the following activities: * They will perform language and cognitive tasks. * Afterwards, they will receive treatments using tablets and headphones at no cost to them. * The experimental treatments (recursive self-feedback procedures) entails responding to prompts, listening to playbacks of their speech response and attempt to minimize/correct the errors in the next attempt. This process will be repeated multiple times per prompt. * The experimental treatments are two: an adaptive version that adapts the complexity of the treatment prompt and a non-adaptive version that does not adapt task complexity. * Researchers will compare the experimental treatments to see if both have similar effects on improving spontaneous speech production.

Arms

  • Experimental: 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. It adapts across narrative prompts with low and high complexities.
  • Experimental: Non-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.

Primary Outcome Measure

Speaking rate [ Time Frame: Within 1 week before treatment and within 1 week after treatment. ]
