Multiple Virtual Identity Awareness Supported Narrowcasting Instant Voice Communication System

In recent years,with the popularity of mobile devices and mobile networks,people are increasingly inclined to use teleconferencing to replace traditional voice calls and real-life meetings.And because of this year's co VID-19 outbreak around the world,distance education and telecommuting have come to rely heavily on teleconferencing.However,at present,the mainstream teleconference software in the market has some problems,such as the lack of user rights,the large amount of invalid information and the inability to attend multiple conferences at the same time.These problems result in very low study or office productivity depending on teleconferencing.Therefore,it is necessary to customize the development of an instant messaging system that can solve these shortcomings.Aim at the above shortcomings that lead to low work efficiency,this paper designs and implements a multi-virtual identity aware narrowcasting instant voice communication system.Among the comcepts,the support of narrowcasting can greatly filter the useless information for each user,and users can customize the information they want to receive and send.At the same time,the introduction of multiple virtual identities can greatly improve the working and learning efficiency of users.This paper firstly investigates the mainstream teleconference software in the market and analyzes the research status of narrowcasting and multiple virtual identities.After detailed analysis of the functional requirements of the system,based on the results of the requirement analysis,the system is designed reasonably and the appropriate system platform and framework is selected.The system is divided into login authentication,instant voice communication,narrowcasting operation,multiple virtual identity and multiple virtual identity awareness and other functional modules.Voice channels are used in the instant voice communication module for audio transmission.Therefore,in the narrowcasting operation module,by subscribing and unsubscribing to the voice channel,the controllable voice stream can be realized point-to-point or point-to-surface,so as to achieve the purpose of information filtering.For the multiple virtual identity module,the status of each virtual identity can be tracked by maintaining a list of local and network unique identities.The multi-virtual identity awareness function relies on the automatic focusing function and spatial sound effect.After the implement of each functional module,the system as a whole and each functional module has been fully tested.The test results show that this system is an instant messaging platform that can fully meet the expected goals and greatly improve the work efficiency.
