Which outcome was not directly examined in the dysarthria study?

Explanation:
In this study, the focus is on specific acoustic and perceptual features of dysarthric speech rather than on how understandable the speech is to listeners. The researchers looked at F0 declination, which tracks how pitch changes across an utterance, and final-word lengthening, a timing/prosody feature. They also explored how those features relate to different loudness levels, showing how loudness can influence pitch and timing patterns. What isn’t directly examined is the overall intelligibility of the speech—the degree to which listeners can understand what’s being said. Intelligibility typically requires separate perceptual testing with listeners, which wasn’t the direct measure used here, even though it can be affected by the prosodic and loudness patterns studied.
