Problems solved by technology

[0004] This search method cannot accurately correct all voice queries only through simple term correction. For example, for query sentences that include repeated segments, accurate query cannot be obtained only through term correction, which affects the search. The accuracy of the engine reduces the user experience

Abstract

The invention provides an artificial intelligence based voice searching method and device. The artificial intelligence based voice searching method comprises the steps of firstly receiving a first query sentence input by a user; then carrying out lexical analysis on the first query sentence and determining a first entity list included in the first query sentence; then carrying out pinyin labeling on each entity in the first entity list and determining a first pinyin list; then determining a second entity list in fuzzy matching with the first pinyin list based on a preset pinyin entity library and further determining a third entity list corresponding to voice input by the user; and then getting rid of one word fragment in a second query sentence which is composed of entities in the third entity list to obtain a third query sentence, wherein the word fragment has the pinyin edition distance to other word segments less than a first preset value. Therefore, influence from a voice identification error to search in a voice searching process is reduced, duplication elimination of repeated fragments is realized, the accuracy of voice searching is increased, and the user experience is improved.

Description

technical field [0001] The present application relates to the technical field of information search, in particular to an artificial intelligence-based voice search method and device. Background technique [0002] Artificial Intelligence (Artificial Intelligence), the English abbreviation is AI. It is a new technical science that studies and develops theories, methods, technologies and application systems for simulating, extending and expanding human intelligence. Artificial intelligence is a branch of computer science that attempts to understand the essence of intelligence and produce a new intelligent machine that can respond in a manner similar to human intelligence. Research in this field includes robotics, language recognition, image recognition, natural language processing and expert systems, etc. [0003] Existing voice search engines, due to the problems of voice recognition accuracy and non-standard pronunciation, voice query sentences (query) are often mixed with ...
