Abstract

The invention discloses a voice input method and device for blind person library Chinese book retrieval, and belongs to the technical field of voice recognition. The method comprises the following steps: identifying identity information of a user through voiceprint recognition; acquiring query voice of a user and analyzing the query voice to obtain a corresponding voice recognition text; performing semantic similarity calculation according to the speech recognition text; and according to a calculation result of the semantic similarity, performing recall and sorting operation on question matching results in the question library, and outputting an optimal matching result. According to the method, the voice recognition technology and the text matching technology are combined, so that the whole voice input system is more intelligent and accurate, and books needed by blind users can be retrieved more accurately and efficiently.

Description

technical field [0001] The invention belongs to the technical field of speech recognition, and more particularly, relates to a speech input method, device and computer-readable medium for retrieving Chinese books in a library for the blind. Background technique [0002] At present, the literature retrieval and input method of the blind library is generally to use a braille point display, connect it to the computer through Bluetooth, and then display the text information on the computer through the screen reading software. The user then operates with the mouse. Because the users who use it belong to a special group, in the usage scenario of the library, the user manually clicks the mouse and then performs the operation, which is time-consuming and labor-intensive. [0003] Corresponding improvements have also been made in response to the above problems. For example, Chinese patent application number CN202010485180.2, published on December 7, 2021, discloses a speech recogni...
