摘要: Devices and methods for speech recognition enable simultaneous word hypothesis detection verification in a one-pass procedure that provides different segmentations of the input. A confidence measure target known is determined according to recursion formula operates on parameters models alternate words, language model lexicon, feature vectors input likelihood ratio decoder. The processed determine an accept/reject signal output with signal. based hidden Markov single optimum state sequence may take form modified Viterbi algorithm.
