Abstract

The present invention provides a voice recognition apparatus and a voice recognition method. An extraction unit respectively extractes feature amounts from a plurality of voice data relative to a plurality of rejected words when the rejected words are applied to recognition words registered in the word dictionary. A collation unit calculates a degree of similarity between the voice signal and each of the recognition words and reject words stored in the word dictionary by using the feature amount extracted by the extraction unit. A result determination unit determines whether or not a word having a high calculated degree of similarity corresponds to a reject word, when the word is determined as the reject word. A reject word generation unit generates an acoustic model from a voice signal having a high degree of similarity to the recognition word to which the reject word is added, calculated by the collation unit, and stores the generated acoustic model in the word dictionary as a reject word relating to the recognition word.

Description

technical field

[0001] The present invention relates to a voice recognition device that judges which of the recognition words the voice signal is based on the similarity between the voice signal and pre-registered recognition words and outputs a recognition result, a voice recognition method of the voice recognition device, and a record There is a recording medium of a computer program for realizing the voice recognition device with a computer. Background technique

[0002] In the existing voice recognition device, there is a device that prepares in advance a word dictionary in which information on recognized words is registered, and a discarded word dictionary in which information on discarded words is registered (for example, refer to Japanese Patent Application Laid-Open No. 2001-147698 Gazette, Japanese Patent No. 3105863). Such a voice recognition device compares voice information input by a speaker with information registered in a word dictionary and a dictionary of d...
