Abstract

A study was conducted to investigate articulatory constraints and its influence on the occurrence of gestural intrusion and reduction errors. Speech errors were generated by a repetitive speech task and two speech rates were employed. These speech rates included normal and fast that were individually determined for each participants and controlled by metronome presentation. Movement data were recorded with the 3D EMA system and the raw movement amplitudes were normalized such that the maximum amplitude of a constriction per trial was set to 100% and the minimum constriction was set to 0%. Data were presented for the bisyllable topcop in the normal speaking rate condition for 8 participants participating in the study. Correlations were also calculated between the normalized amplitude of the target gesture for each separate trial of the study.
