Summary
The tracking procedure trains and evaluates speech reception by measuring correct words per minute. This method effectively assesses communication aids, like vibrotactile-electrotactile devices for lipreading.
Area of Science:
- Audiology
- Speech-Language Pathology
- Assistive Technology
Background:
- Effective training and evaluation of speech reception are crucial for individuals with hearing impairments.
- Existing methods may not adequately capture the nuances of real-time communication and aid effectiveness.
Purpose of the Study:
- To introduce and validate the
- tracking procedure
- as a method for training and evaluating ongoing speech reception.
- To assess the efficacy of a vibrotactile-electrotactile aid to lipreading using the tracking procedure.
Main Methods:
- A talker and receiver engage in a dialogue where the receiver repeats text segments and receives corrections.
- Performance is quantified by the number of correctly repeated words per unit of time (words per minute).
- The procedure was applied to evaluate an aid to lipreading, comparing aided and unaided conditions.
Main Results:
- The tracking procedure demonstrated differences between experimental conditions over time.
- Performance was measured in absolute words per minute, the increment of aided over unaided scores, and percentage of normal listening rate.
- Identification test data for syllables, words, and sentences were also analyzed.
Conclusions:
- The tracking procedure is a viable method for communication training and evaluation in aural rehabilitation.
- It offers a robust way to assess the effectiveness of various communication systems and assistive devices.
- The procedure provides objective, quantifiable data on speech reception performance.
