Title:
CONTINUOUS VOICE RECOGNITION DEVICE AND ITS PROGRAM
Document Type and Number:
Japanese Patent JP3813491
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To provide a continuous voice recognition device, which determines a recognition result in an early stage with good real-time response and has high recognition precision and a light arithmetic processing load, even when a detailed sound model and language model are used for voice recognition, and its program.
SOLUTION: The continuous voice recognition device is equipped with means 21 and 31 of storing a simple acoustic model, a simple language model, a detailed acoustic model, and a detailed acoustic model, a 1st path processing means 20 of making a forward search for a continuous voice by using the simple acoustic model and simple language model and generating a word start- end list consisting of respective words as candidates and information on their start-end time, and a 2nd path processing means 30 of making a forward search for the continuous voice according to the information on the start-end time within a range of words included in the word start-end list by using the detailed acoustic model and detailed language model and generating a word array corresponding to the continuous voice.
