Voice activity detection for piano online teaching based on digital network system

Abstract

Abstract The purpose of this paper is to build a dedicated network dedicated to a complete digital network. So we investigated the necessity of network construction and digital and communication. After a lot of digital network research and detailed analysis of the system, the use plan of the report and further analysis. The purpose of the piano network system design is to solve traditional face-to-face education problems such as economy, time-consuming, physics, transportation, etc., and to make effective use of rapid development. In particular, it integrates all aspects of society with the network piano itself as learning Platform. By designing the resources and network system platform for effective piano learning, it can not only save social resources, but also provide convenience for students and teachers. This article first explains the basic principles related to voice activity detection, expounds the voice signal model, discusses the higher ratio of parameters used in conventional voice activity detection activities, and promotes simulation-related experiments to verify it. With the advent of the era of big data and the increase in network bandwidth, the previously limited network bandwidth resources have been improved, allowing users to perform a large number of online management. For example, piano online teaching technology based on broadband Internet, remote Internet in the field of information transmission, control technology, and piano, especially the Internet-based piano online teaching system, are all important industries in the era of big data.
