Methods and apparatus for non-acoustic speech characterization and recognition

(57) By carrying out simultaneous record of summary EM wave reflection (21) and the sound wave speech information (24), the position and speed of the organ of speech (2, 3, 4) concerned at the time of a sound being articulated can be defined about each sound wave phonetic unit (20). The feature vector (6, 7, 8, 9) described to a required grade about the well defined time frame and sound can be formed. This kind of feature vector (6, 7, 8, 9) can describe uniquely the characteristic of the phonetic unit (20) articulated in each time frame. Discernment of the state of an audio start, refusal of external noise, the sound-ized pitch period, and an articulation organ, exact timing, and a speaker, sound wave phonetic unit (20) recognition, and the mechanics parameter of an organ can be determined.
