Abstract
This pilot study tested the prediction that covert speech activity measured by lip EMG(μv) is significantly greater during the presentation of prerecorded speech than in a ‘speechless’ video-viewing test condition and conditions of rest. A single-subject multiple-baseline design was used and nondominant forearm EMG(μv) activity was also measured for comparison purposes. Analysis showed a significant increase in lip EMG(μv) activity in 1 out of 2 rest-to-test conditions involving the presentation of prerecorded overt speech. There was no significant difference in the subjects' mean lip EMG(μv) values across 3 test conditions, however.
