GENERATION OF DATA FROM SPEECH OR VOICELESS MOUTHED SPEECH

摘要

A plurality of magnets (10) are attached to respective different parts of the mouth of a human. A plurality of magnetic field sensors (26A-26F) are mutually spaced from one another and mounted on a support worn by the human. As the human speaks or makes voiceless mouthed speech, the magnetic field intensifies experienced at the sensors (26A-F) vary, because of the movement of the mouth. The sensors (26 A-F) detect the changing intensities and pass them to a processor (32). The processor (32) can use a variety of methods to analyse the signals from the sensors (26 A-F). The field intensity signals can be used for, for example, determining words spoken, control of equipment and identification of individuals. Where the human is incapable of voicing speech, mouthed speech can be analysed and converted to artificial speech.
