Telepractice in speech-language pathology: Assessing remote speech discrimination

To evaluate adult remote performance in speech discrimination on the Temple Assessment of Language and Short-term Memory in Aphasia (TALSA), and to compare to remote performance in NU-6 word repetition and participant ratings of self-perceived hearing ability obtained via remote session.

Sixty older adults completed TALSA speech discrimination of concrete, low frequency words and of non-words via telephone. Remote repetition of words controlled for sound frequency was assessed using the Northwestern University (NU-6) word lists administered in live voice and recorded voice conditions. Forty-six of the participants completed questionnaires about their hearing via Zoom videoconference.

Mean performance in TALSA speech discrimination for words was similar to performance in NU-6 word repetition. Word repetition of NU-6 lists did not differ significantly for live voice versus recorded voice conditions. TALSA non-word speech discrimination was significantly worse than TALSA speech discrimination for words and was associated with age and self-reported hearing ability.

TALSA speech discrimination can be administered remotely to evaluate potential perceptual influences on auditory comprehension. In remote assessment, participants demonstrated the expected pattern of more accurate speech discrimination for word stimuli than for non-words. The non-word TALSA condition may be particularly useful for detecting speech perception impairment, both in face-to-face and telepractice sessions. Similar performance of participants in both live voice and recorded conditions of the NU-6 word lists suggests that recordings used in SLP receptive language or memory assessment, including the TALSA, need not be abandoned in favor of live voice to support audition during telepractice.
