Substitution of Vocal Folds for Voice Generation by Means of Intra-Oral Pulse Generator

Human beings vocal folds act as a carrier pulse (or pitch-pulse, as said) for normal voice, with that, other parameters such as oral cavity structure or its elements positioning, shape this signal in what we know as speech. This characterizes normal voice as signals with a high concentration of energy at the lower bands of the frequency spectrum. This research defines and implements a device capable of generating a carrier signal (pitch-pulse) capable of, eventually, acting as a substitute for the vocal folds. This device generates a constant low frequency periodic pulse that allows the user to shape it when used intra-orally, just as one would do for normal speech creation. This research also evaluates the results of using such substituting device, and compares it with the results of normal speech.
