隨著科技的進步，具有連網功能的裝置數量不斷上升，至今已逐漸邁向物聯網時代。物聯網在人類生活上的應用，最具代表的應用就是智慧家庭系統。現今的智慧家庭系統(如Nest、Samsung SmartThings)均提供可控制智慧家庭的手機應用程式，使用此手機應用程式可隨時讀取家中智慧家庭裝置的狀態；也可透過此手機應用程式控制智慧家庭裝置。然而在科技的進步下，人機互動的方式已從過去常用的觸控發展出新的互動方式─聲控。
本論文為分別研究兩種語音助理：Amazon Alexa與Google Assistant，並分別實作其開放的開發技術，在Alexa部分，實作其開發技術套件，自行實作語音功能與開發語音服務；Google Assistant部分，實作其開放的開發技術平台Actions on Google，自行開發語音服務。最後，對於兩系統的實作成果做出比較與分析，提供開發者更剖析的了解。
本論文在實作上分為兩部分，第一部分為實作出兩系統(Amazon Alexa與Actions on Google)完整的系統架構，其中包含了裝置、終端與外部web service；第二部分則將實作出的完整系統與IP Camera做整合，達到能夠使用聲控控制多台IP Camera的功能。本論文實作兩種智慧家庭聲控系統，並延伸控制多個IP Camera，為開發人員完整解析兩種聲控系統。

As technology advances, the number of devices with networking capabilities increased in a very fast speed, and it has been gradually moving towards the age of Internet of things. As of Internet of things’ applications in human life, Smart Home system is the most distinctive representative. Companies such as Nest, Samsung develope smart home systems and smart home apps. Users can use these apps to read smart home devices’ status at any time; also user can set the status of Smart Home device through this app. However, in the progress of science and technology, human-machine interface control is no longer confined to touch control, but evolves to a new human-machine interface control ─ Voice Control.

This study gives more information about how to build a voice control system with Amazon Alexa voice development technology. Besides, Google Home smart home assistant, recently released and implemented by its open development technology platform, enables developers to develop their own voice services. Finally, the research gives some analysis and result from the implementation of the two systems, and provides developers more in-depth understanding.

This study is divided into two parts. The first part is the entire architecture of the systems (Amazon Alexa and Actions on Google) which contain devices, endpoints and web services. The second part is that the system mentioned above combined with IP cameras, and it can achieve a function that controls multiple cameras with voice control. In conclusion, this research implements two kinds of voice control systems of smart home, and controls multiples IP cameras. Furthermore, this paper provides the analysis between Amazon Alexa and Action on Google completely.
