Control method of speech soft switch and its application in geographic information system

Abstract

The invention discloses a control method of a speech soft switch, which is characterized in that a specific closed keyword and a specific broken keyword are respectively added before and after a speech command according to a certain rule on the basis of the prior commercial speech input module so that a soft switch control mechanism capable of rapidly shielding outside noise and being switched todifferent latter command branches is established and the switch function of speech input in software environment is realized. The invention has the following processing process: a character string ofa sentence segment with noise is identified and obtained through the speech input module, and a limited number of closed keywords and broken keywords in an established switch keyword library are utilized, matched and calculated; if the character string of a sentence segment with noise comprises a closed keyword, a corresponding command operation is started and executed according to the closed keyword, or else the character string of a sentence segment with noise is judged to be a noise character string, and no command operation is executed. The invention is easy and practical and can improve the intellectualized and humanized degree of a geographic information system in the aspect of the speech input.

Description

Control Method of Voice Soft Switch and Its Application in Geographical Information System technical field The invention relates to a voice processing and control method, in particular to a voice control method through Chinese voice analysis technology, fuzzy matching technology and geographic information system technology. Background technique Speech technology is an artificial intelligence information technology developed with digital signal processing technology in the 1960s. Its application in computer software systems has the advantages of easy grasp, convenient operation, and high degree of intelligence. At present, voice technology has transitioned from an experimental system to a practical product. Many related companies, research institutes, and colleges and universities at home and abroad have invested a lot of manpower, material resources, and financial resources in technological innovation and system research and development. IBM, Microsoft, Nuance, AT&&T, And m...
