The present study examined the effects of speaking mode (clear, habitual, slow speech) on speech production and speech perception of individuals with and without Parkinson's disease. In the speech production task there were 21 speakers who read the Farm passage in habitual, clear and slow speech modes. Acoustic analysis involving the assessment of the first and second formant frequencies was performed using vowel space areas, vowel dispersions, /i-alpha/ distances for both tense and lax vowels produced in each of the speaking conditions. Duration ratios of both the tense and lax vowels were also examined in each condition. Effects of the conditions on perception were investigated in two listening tasks. In the first task, 3 listeners heard a subset of speakers from the production portion. In a forced choice task the listeners then selected the vowel they preferred in a given speaking condition. In the second listening task, 10 listeners used a 7-point Likert rating scale to rate 4 sentences produced in each of the 3 conditions for the 21 speakers. Production results showed that vowel space areas were larger in the clear and slow conditions compared to habitual, with no statistically significant difference between clear and slow. Results from the first listening task showed a preference for vowels in clear speech mode, and the second showed that speakers were rated most intelligible in clear speech mode.
