Application ID: 13155218

Base Claim:
1. A method for detecting and recognizing speech, comprising the steps of: remotely detecting body motions from a speaker during vocalization with one or more radar sensors supporting a plurality of simultaneous diverse wavelengths, wherein the body motions comprise small vibrational displacements and articulator motions; extracting Doppler signals correlated with the speaker vocalization; developing feature vectors utilizing the vocalization Doppler signals; and recognizing words associated with the feature vectors with a word classifier.

Claim 10:
10. The method of claim 1 , wherein the step of recognizing words associated with the feature vectors with a word classifier, comprises the steps of: partitioning the feature vectors into subsets of contiguous feature vectors associated with an isolated word with a word boundary algorithm, wherein the word boundary algorithm determines the start and stop times of an isolated word from statistics and rules; utilizing a word classifier for each feature vector to produce word decision data; weighting the word decision data of each word classifier to determine the final word decision data.
