Intelligibility of older versus younger adults' CVC productions.

In studies of aging voice, listeners have reported that older speakers articulate less precisely than younger speakers. To determine if intelligibility changes with age, younger and older adults read CVCs embedded in a carrier phrase. Listeners reported the target word said by the speakers. More errors were made on the older speakers' productions than on the younger speakers', although age alone was not statistically significant. Results are reported for age, sex, and position of error in the target word.
