CONTINUOUS INPUT SPEECH RECOGNITION DEVICE AND CONTINUOUS INPUT SPEECH RECOGNIZING METHOD

摘要

PROBLEM TO BE SOLVED: To make it unnecessary to perform speech segmentation in a speech input stage with respect to continuous input speech becoming objects of recognition, and also to improve recognition rate. SOLUTION: A continuous input speech recognition device of the present invention is a device which performs recognition of input speech using a sound model in which features of phonemes are held, and a language model in which contents of utterance are held and a dictionary in which correspondence among phonemes and morpheme elements are held, and the device is equipped with; the language model in which a plurality of sentences are connected with pause signs; the sound model in which features of phonemes each of which corresponds to each pause sign are included; the dictionary in which elements each of which corresponds to each pause sign are included, a first recognition means which detects the position of the pause sign in the inputted speech; a decision means which decides an utterance section by making the input speech of the head position of the input speech which are positioned before the detected pause sign or the input speech which are positioned on and after the previous pause sign one sentence; and a second recognition means which performs speech recognition to the decided utterance section.
