AI Technical Summary

Technical Problem

In the complex background noise environment of the exhibition hall, the distortion of tourists' voice signals makes it impossible for voice signal processing to accurately extract key semantic information, resulting in low response efficiency and accuracy of the intelligent guide voice question and answer system in the exhibition hall for complex voice questions.

Method used

A speech signal noise interference monitoring module is used for noise assessment, and adaptive noise reduction measures are used to improve the clarity of the speech signal; a key semantic recognition monitoring module is used to identify, analyze and correct key semantics of speech problems; and a speech question-and-answer response efficiency monitoring module optimizes the response process and improves response efficiency through a triplet retrieval strategy.

Benefits of technology

It effectively reduces the interference of background noise on the voice signal, improves the clarity of the voice signal and the accuracy of key semantic recognition, reduces invalid retrieval steps, and improves the response efficiency and accuracy of the intelligent guide voice question and answer system in the exhibition hall.

Abstract

The invention discloses an exhibition hall intelligent guide voice question and answer optimization system based on multi-modal data, and relates to the technical field of intelligent voice question and answer data processing. The exhibition hall intelligent guide voice question-answer optimization system based on the multi-modal data comprises a voice signal noise interference monitoring module; a key semantic recognition monitoring module; and a voice question-answer response efficiency monitoring module. According to the method, voice signal noise interference evaluation is carried out to determine whether to take an adaptive noise reduction measure, then, based on a voice problem key semantic recognition analysis result, whether to take key semantic recognition correction is determined, and finally, based on a voice problem answer response judgment result, whether to take a triple retrieval strategy is determined. The effect of improving the response efficiency of complex voice question answering is achieved, and the problem that in the prior art, multi-modal data-based exhibition hall intelligent guide voice question answering optimization data is low in accuracy is solved.
