Phonetic complexity effects
Conduct a comprehensive kinematic assessment using state-of-the art 3D speech tracking technology on individuals with ALS and PD as well as healthy talkers to identify articulatory motor disturbances as a function of phonetic complexity and dysarthria severity. Phonetic complexity will be experimentally manipulated using the consonant and vowel complexity classification system proposed by Kent (1992) that takes into account the underlying articulatory motor adjustments required to produce various speech sounds.
