Embodiment 1

[0069] This embodiment provides a speech semantic recognition method for a service robot, which specifically includes the following steps:

[0070] S1. System lexicon modeling:

[0071] S101, set up a thesaurus database, the thesaurus database includes a pronoun database, a verb database and a noun database, and words and idioms that are pronouns, verbs and noun attributes in Chinese characters are stored in the corresponding pronoun database, verb database and noun database respectively ;

[0072] S102, at the same time, establish a semantic framework database, said semantic framework database includes the possible combinations of stored words and the corresponding Chinese meanings when combined together;

[0073] S103. Simultaneously establish a lip language pattern library, and the established pattern library is recognized by the facial lip language video operation to obtain the pattern feature code or reversely deduce the standard pattern feature code from the Chinese tex...

Abstract

The invention provides a speech and semantic recognition method of a service robot. The method comprises: system word library modeling is carried out; to be specific, a word library database is established and then a semantic frame database is established; a lip language mode base is established; a system uses a speech recognition system to collect a speech instruction inputted by a user and a face video and speech and semantic recognition and video segment lip language recognition are carried out respectively; and according to a combined recognition result, a determined Chinese semantic information is displayed at a display interface. Therefore, a noun database and a semantic frame database are established for different service fields; and on the basis of the word library database, the semantic frame database, and the lip language mode base, the robot understands the Chinese meaning expressed by the speech instruction, so that speech and semantic recognition becomes accurate.

Description

technical field [0001] The invention relates to a voice semantic recognition method, in particular to a voice semantic recognition method for a service robot. Background technique [0002] An important branch of computer science is "artificial intelligence", which attempts to understand the essence of intelligence and produce a new intelligent machine that can respond in a similar way to human intelligence. Research in this field includes robotics, language recognition, Image recognition, natural language processing and expert systems, etc. [0003] In terms of natural language processing, how to make robots recognize and understand human language, and simulate human thinking to think and reason is an important measure to realize the great ideal of "artificial intelligence". Regardless of the language environment of Chinese or English, except for individual exceptions such as "you", "me" and "he", phrases are the smallest unit of human expression semantics. [0004] What i...
