Problems solved by technology

[0020] However, even though large amounts of learning data can be collected from media such as books, newspapers, and magazines, as well as from text on websites, selecting the phrases a speaker is likely to utter is laborious and makes large corpora completely incompatible with meaning. Figure 1 To is also difficult
Furthermore, it is difficult to specify the intent of each text or classify text by intent
In other words, it is not possible to collect a corpus that exactly matches the speaker's intent

Embodiment Construction

[0062] The present invention relates to speech recognition technology, and has main features of focusing on a specific task, accurately estimating the intention in what a speaker utters, thereby solving the following two points.

[0063] (1) Simply and appropriately collect a corpus with what a speaker might say for each intent.

[0064] (2) Matching arbitrary intentions to utterances (which are inconsistent with the task) is not enforced, but rather ignored.

[0065] Embodiments for solving these two points will be described in detail below with reference to the accompanying drawings.

[0066] figure 1 The functional structure of the speech recognition device according to the embodiment of the present invention is schematically shown. The voice recognition device 10 in the drawing is equipped with a signal processing section 11 , an acoustic score calculation section 12 , a language score calculation section 13 , a dictionary 14 and a decoder 15 . The speech recognition d...

Abstract

The invention discloses a voice recognition device and a voice recognition method, a language model generating device and a language model generating method, and computer program. The speech recognition device includes one intention extracting language model and more in which an intention of a focused specific task is inherent, an absorbing language model in which any intention of the task is not inherent, a language score calculating section that calculates a language score indicating a linguistic similarity between each of the intention extracting language model and the absorbing language model, and the content of an utterance, and a decoder that estimates an intention in the content of an utterance based on a language score of each of the language models calculated by the language score calculating section.

Description

technical field [0001] The present invention relates to a speech recognition device and a speech recognition method for recognizing the content of a speaker's utterance, a language model generation device and a language model generation method, and a computer program, and more particularly, to a method for estimating a speaker's intention and A speech recognition device, a speech recognition method, a language model generation device, a language model generation method, and a computer program for grasping tasks executed by a system through speech input. [0002] More precisely, the present invention relates to a speech recognition device and a speech recognition method, a language model generation device and a language model generation method, and a computer program for accurately estimating intent in speech content using a statistical language model, and more particularly, to Speech recognition device and speech recognition method, language model generation device and languag...
