Speech articulation is executed by motor commands to various speech muscles. The subsystem of motor programming autonomically outputs a sequence of commands according to intended signals for articulatory target. The present study examined such a function of motor program for coordinated speech gestures by speculating motor commands from electro-myographic (EMG) data. A waveform separation technique was applied to extract component commands from ensemble average EMG wave-forms. The data used in this study contained six tongue muscles and two other muscles, which were recorded during production of /apVp/ word utterances. The motor score was obtained from the results, which demonstrated temporal and hierarchical organization of sequential control on motor commands.
