Local Speech Rate: Relationships Between Articulation and Speech Acoustics

The relationship between the displacements, velocities, and accelerations of the articulators and speech rate is investigated experimentally. Especially, we address the question as to whether it is possible to predict the speech rate from articulatory kinematics by means of a linear regression model. Two different kinds of corpora have been recorded. The first consists of only two short sentences differing in their vowel/consonant quotient and read aloud with seven different speech rates. The second was two readings of a 5-minute short story. While the first corpus supported a close relationship, the second revealed a correlation coefficient of only r = 0.5 which provides evidence against a close relationship between kinematic variables and speech rate.
