Summary
Watching yourself speak significantly improves lipreading skills for deaf adults, especially when feedback is provided after speech practice. This multisensory approach enhances understanding of spoken words, even those not specifically trained.
Area of Science:
- Audiology
- Speech-Language Pathology
- Rehabilitation Science
Background:
- Lipreading is a crucial skill for individuals with hearing impairments.
- Previous research suggests self-viewing speech aids lipreading.
- The efficacy of this method in diverse deaf populations requires further investigation.
Purpose of the Study:
- To replicate findings on self-viewing speech improving lipreading.
- To investigate the impact of feedback source (self vs. trainer) and timing (during vs. after production).
- To assess generalization of lipreading skills to untrained words.
Main Methods:
- Four groups of 12 young-adult deaf subjects evaluated self-viewing vs. trainer-viewing feedback.
- Feedback timing (during or after speech production) was also assessed.
- Lipreading accuracy and response time (RT) were measured before and after training.
Main Results:
- Viewing self-speech after production significantly improved lipreading accuracy for trained words.
- Generalization to untrained words was observed in the self-viewing group.
- Both self-viewing groups showed gains on trained and untrained items, unlike trainer-viewing groups.
Conclusions:
- Multisensory feedback through practicing lipreading of one's own speech is beneficial.
- This approach enhances lipreading accuracy and generalizes to untrained items.
- The findings are applicable to young-adult deaf individuals with varying speech intelligibility.
