Acquisition and its Basic Processing Technology of Multimedia Vocal Signal

Abstract

This paper briefly studies the method of collecting audio signals and the method of adding noise to audio signals. It comprehensively applies various basic knowledge of digital signal processing, and then performs spectrum analysis on noise-free frequency signals and spectral analysis of noise-added frequency signals, and filtering processing. Through theoretical derivation, the corresponding conclusions are drawn, and then MATLAB is used as a programming tool to carry out computer implementation to verify the conclusions derived. In the research process, the filter processing was completed by designing the IIR digital filter and the FIR digital filter, and MATLAB was used to draw the graphics and calculate and simulate some data in the whole design.

Artificial Intelligence Interactive Design System Based on Digital Multimedia Technology

“…If these vulnerabilities are used illegally, artificial intelligence interaction will suffer a huge threat. erefore, the research on artificial intelligence interaction has aroused the emphasis of research in China and other countries [9]. Under normal circumstances, it is difficult to obtain satisfactory results using the previous data methods to solve the problem of data encryption and artificial intelligence interaction.…”

“…Using graphics, it is possible to describe the steps that enable designers, users, and artificial intelligence interactive design interfaces to interact with high precision and to achieve transmission and acquisition of information. e process for completing the interaction between the designer and the artificial intelligence interactive design interface can be considered as the step of converting raw data into artificial intelligence interactive information [9]. e interaction between the user and the artificial intelligence interaction design interface can be regarded as the step of transforming the artificial intelligence interaction information into knowledge.…”
