Embodiment Construction

[0048] In order to make the above objects, features and advantages of the present application more obvious and comprehensible, the present application will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0049] refer to figure 1 , which shows a flow chart of a speech recognition method in Embodiment 1 of the present application, specifically including:

[0050] Step 101: Receive multiple candidate recognition results output by the speech recognition system, and match the multiple candidate recognition results with templates in the knowledge base, wherein the knowledge base includes entity vocabulary and templates, and the entity words The table stores entity words, and the template stores writing rule sentences conforming to regular expressions.

[0051] The speech recognition system can save and output a series of possible recognition results, which are called multiple candidate recognition results (n-...

Abstract

The invention provides a speech recognition method and a speech recognition device. The method comprises steps that: multiple candidate identification results outputted by a speech recognition system are received, the multiple candidate identification results are matched with templates in a knowledge base, the knowledge base comprises an entity word table and the templates, and template storage is in accordance with writing rule statement of a regular expression; if the multiple candidate identification results are not matched with the templates in the knowledge base, distances from the multiple candidate identification results to the templates in the knowledge base are calculated; matching scores of the multiple candidate identification results are acquired according to the distances and trust degrees of the multiple candidate identification results, the multiple candidate identification results are respectively matched with the templates in the knowledge base according to the matching scores to acquire matching degrees of the multiple candidate identification results and the templates in the knowledge base; according to the matching degrees, the identification results after matching are outputted. The method solves a problem of influence of a speech recognition error on a question-answering system is solved.

Description

technical field [0001] The present application relates to the field of speech recognition, in particular to a speech recognition method and device. Background technique [0002] In recent years, with the development of language processing technology, intelligent question answering system has received great attention. From the popularity of the chat software "little yellow chicken" to the popular answering robots on major network platforms, intelligent question answering system has been widely used in many fields. widely used. [0003] Most question answering systems use the form of text input as the input of the question answering system, which is cumbersome and time-consuming, especially on devices without keyboards such as mobile terminals (such as mobile phones) or for people with difficult operations such as the elderly and the disabled, text input becomes difficult. Very difficult. Therefore, a question answering system based on voice input emerged as the times requir...
