This study compared the ratings of intelligibility and acceptability of three groups of listeners (normal younger adults, older normal adults, and experienced speech-language pathologists) for four older speakers, two of whom had dysarthric speech. Intelligibility ratings and acceptability ratings decreased from the normal speakers to the impaired speakers. Also, the two ratings were highly correlated showing that, as intelligibility (an objective measure) dropped, acceptability (a subjective measure) also dropped. The highest intelligibility scores were achieved by the speech-language pathologists. This group also provided the lowest acceptability ratings for the normal speakers suggesting that they might have different constructs as to the meaning of acceptability.
