Method for off-line voice retrieval of products under network-free condition

Abstract

The invention discloses a method for off-line voice retrieval of a product under a network-free condition, and the method comprises the following steps: S1, developing and integrating an off-line database by using an Android SDK, downloading voice, characters and a special scene knowledge graph which can be identified in the database, and classifying the off-line database; S2, enabling a user to receive the voice through a voice receiving device; enabling the voice to be matched with an offline database, recognizing and converting the voice, and matching a knowledge graph of a special scene according to characters. According to the method, the offline classification database is set through the Android SKD device, the corresponding content is downloaded in the database, and the data in different scenes are independently stored; during the voice recognition, the voice is firstly converted into the characters, then the converted content is classified, and the content is searched in the corresponding classification database, so that the offline voice recognition classification is clear, the range needing to be searched is quickly positioned during recognition, and the range selection is quicker.

Description

technical field [0001] The invention relates to the technical field of voice search, in particular to a method for offline voice search for products without a network. Background technique [0002] Voice search refers to allowing the use of mobile phones and computers to search by speaking to the mobile phone or computer, that is, the content uploaded by the device is recognized by the server, and then information is searched based on the recognition results. Voice search technology has become a daily routine. The more important part enables users to conduct voice control anytime and anywhere, bringing greater convenience to people's lives; [0003] However, the current voice search technology in the offline state is not mature enough, the use of voice recognition in the disconnected state is more troublesome, the search range in the offline state is limited, and the processing speed of data is slow, resulting in low accuracy of search results , which has a certain impact o...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a method for offline voice search products under the condition of no network, which can effectively solve the problem that the current voice search technology in the offline state is not mature enough in the above-mentioned background technology, and the use of voice recognition in the disconnected state is relatively troublesome. The search range is limited, and the data processing speed is slow, resulting in low accuracy of the search results, which has a certain impact on the search and cannot meet the needs of the search.
