Patent ID: 6928409

Claim:
A speech recognition system, comprising: a first section having an input for receiving a spoken command and providing a polynomial expansion of a feature vector generated for the spoken command in a non-training mode; a second section that provides a polynomial expansion of a feature vector generated in a training mode; and a third section having a correlator block that correlates the polynomial expansion of the feature vector from the first section with the polynomial expansion of the feature vector from the second section, wherein the third section performs a Hidden Markov Model statistical analysis of a correlated feature vector wherein the third section further includes: a sequence vector block having an input for receiving a signal from the correlator block; an HMM table having an output; and a Viterbi block having a first input coupled to the sequence vector block, a second input coupled to the HMM table, and an output that provides a state sequence that maximizes a probability of identifying the spoken command.
