A dictionary retrieval method and system searching for Chinese characters via voice

Abstract

The invention provides a dictionary retrieval method searching for Chinese characters via voice. The method comprises the steps of acquiring voice input information containing a target Chinese character; identifying the voice input information and obtaining matching candidate Chinese characters, and selecting the target Chinese character from the candidate Chinese characters for retrieval. A dictionary retrieval system searching for Chinese characters via voice comprises a voice input module, a voice identification module, a retrieval module, and a database module. Voice input of multisyllable terms, phrases or sentences containing a target Chinese character is performed; identification and matching are performed on the voice; before a voice identification result is output, the highest possible matching Chinese character is converted into a group of syllable sequence and mapping of homosyllable terms or phrases is carried out; mapping and output of the mapped homosyllable terms or phrases as well as the previously-identified Chinese character and a Chinese coded character set is carried out, so that the disturbance of homophonous characters of a target to-be-searched-for Chinese character to the target Chinese character is effectively reduced, the number of candidate characters is greatly reduced for users and high-efficiency dictionary retrieval can be achieved.

Description

technical field [0001] The invention relates to an electronic dictionary retrieval method, in particular to a dictionary retrieval method and system for querying Chinese characters by voice. Background technique [0002] Traditional paper-based dictionary retrieval uses pinyin or radicals for retrieval. With the changes in people's work and study methods and the rapid development of mobile Internet technology, people's learning methods are gradually shifting from traditional paper to electronic learning. Electronic learning through mobile terminals enables people to learn anytime, anywhere. For this reason, the paper dictionary has also expanded the electronic dictionary. [0003] The existing Chinese electronic dictionary query method needs to input the word to be queried first, and then the explanation of the word can be found. The lack of pinyin and the cumbersome input method will cause inconvenience to the search and even cannot complete the search. Therefore, the mark...

AI Technical Summary

Problems solved by technology

[0005] When the target Chinese character to be checked is input by recognizing the pronunciation of a single target Chinese character, the problem of low input efficiency will occur due to the existence of a large number of homophones

[0006] For a dictionary, the word is its most important query item, the existing dictionary can only provide voice input query for words or sentences, and the voice input query for a single Chinese character is less used because of its low efficiency

[0007] The general monosyllabic retrieval method displays candidate words according to their common frequency. This kind of display is not effective for dictionary users because most dictionary users want to look up rare words such as low-frequency words, unknown or rare words, etc. Therefore, a more accurate understanding of the user's word search purpose to minimize the number of user candidate words is very necessary, and how to quickly filter out the Chinese characters to be searched to improve retrieval efficiency is also very necessary
