The rapid rate of speech, monotone, quite voice and imprecise consonant production are probably a reflection of limited range and paucity of movement. hesitation inappropriate silences, and then progressive blurring of articulation seem to be the vocal correlate of festination of gait. palilalia, the repeating of words or syllables, is often present.
