Research And Application Of Smart Speaker Based On Alexa

In recent years,with the breakthrough development of artificial intelligence-related technologies,voice recognition and other technologies have been pushed to the forefront of the times.Voice recognition has been applied on mobile terminals using mobile phone voice assistants,and on home terminals,smart speakers have been used as carriers.The speaker is not only a shortcut for ordinary households to access artificial intelligence,but also an important traffic entry point for smart homes in the future.Therefore,in recent years,both abroad and domestic have set off a boom in smart speaker research.On the other hand,with the improvement of living standards People's pursuit of entertainment methods is diversified.Portable electronic devices are not enough to meet people's home life needs.Speakers,as common home electronic products,have a high universalization rate and retention rate.This paper is related to artificial intelligence.The ingenious combination of technology,Internet technology,and ordinary speakers,research and realize a smart speaker,as an effective entry point for AI to enter the lives of ordinary people,the related research has significant significance.This project comes from the horizontal scientific research project that m y laboratory cooperates with Zhongshan Litai Technology Co.,Ltd.The project takes Amazon's Alexa voice interactive service as the starting point to design and implement an Alexa based smart speaker,in addition to the basic Alexa voice Service service,the thesis also customized some related skills for the smart speaker,at the same time,designed and implemented the front and back system for the smart speaker,which is used to support the operation of the smart speaker entertainment and other related functions.The design and implementation of this topic are mainly divided into two parts from the structure,and the following will explain the core work of the two major parts of this paper.The first chapter is the voice interaction part of the smart speaker.This part is mainly designed and implemented from two aspects.Firstly,based on Alexa voice service,Alexa's basic voice interaction service is introduced to make the speaker have the voice processing ability in the cloud,while the local end only carries out voice acquisition and the play of the cloud response.Then this paper is based on Alexa skills Kit has customized play related skills for smart speakers on demand,such as play and pause skills,to improve user experience.In addition to the design and implementation of voice interaction,this paper also studies the principle of voice recognition and the process of voice interaction.Then there is the front and background system part of the smart speaker.This chapter builds the implementation framework of the background system based on Django,and designs the service support system for the smart speaker,so as to realize such operations as playing music and radio programs,viewing the inform ation of the smart speaker equipment,etc.The user interacts with the system through the front desk,and the system transmits the interactive information post of the front desk to the background for logical processing before execution This part of functions mainly includes registration and login module,distribution network module,music and radio module,smart speaker monitoring module,user center module,music recommendation module,background management module.This thesis will design and implement each function module of this part through two chapters.
