Document Type and Number:
Japanese Patent JP2018151413
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To precisely recognize voice.SOLUTION: A voice recognition device comprises a calculation section and a search section. The calculation section calculates a score vector sequence on the basis of a voice signal. The search section detects a path following an input symbol with which a likely acoustic score in the score vector sequence can be obtained by searching a search model which is previously registered, and outputs an output symbol allocated to the detected path in the search model. A symbol set comprises a recognition object symbol showing phonemes of a recognition object, and an additional symbol showing at least one of a filler, a non-fluency and a non-language sound as input symbols. The search model comprises a plurality of paths to which the input symbol sequence where one or more input symbols are arranged and the output symbol are allocated. The search section starts search of the path corresponding to a new output symbol from a score vector next to the score vector including the received additional symbol when the search section receives the additional symbol as the input symbol with which the likely acoustic score can be obtained.SELECTED DRAWING: Figure 1
