This thesis is based on the analysis of two distinct phenomena, the voice fundamental frequency response, and the electromyographic response of the orbicularis oculi muscle, to high intensity, impulse type stimuli. The analysis performed were statistical analysis, and System Identification modeling, of both phenomena. An additional System Identification analysis was performed on the voice fundamental frequency, using a descriptive value of the electromyographic response as a stimulus parameter. The purpose of that last analysis was attempting to combine both System Identification analysis, and showing the connection between the two phenomena.
