Abstract

We report preliminary results for the effect on tongue movements of varying speaking rate. Speech acoustics and tongue tip and body kinematic data were collected using electromagnetic articulography (EMA) [Perkell et al., J. Acoust. Soc. Am. 92 (1992)]. A subject read each one of 20 sentences three times in a row with a predefined order of combination of three speaking rates (normal, medium, fast). Velocity and acceleration were derived using functional data analysis (FDA) [Ramsay et al., J. Acoust. Soc. Am. 99 (1996)] for smoother estimation of acceleration from the displacement data. Global utterance analyses of phase‐space and variability in the displacement‐velocity and the velocity‐acceleration relations indicate that the fast speech exhibits comparable tongue tip displacements to normal speech but significantly larger accelerations (p<0.00). The difference in the order of combination of speaking rates (e …
