This article presents a system which has been called “Voice Controller”, built for the purposes of the Thesis of Ilias Loukopoulos. It initially gives theoretical aspects related to the system and gives the proper lines in which fields the research should get focused. The Internet of Things, the speech services and a Wireless Sensor and Actuator Network are the main fields Secondly it gives an overview of the use of Personal Assistants and the Speech recognition services in the Internet of Things environment. Several Assistants and Speech recognition services have come to enhance the Internet of Things and eventually assist people in their life by simply using their voice. It continues by comparing the potential of several speech services and the use that may provide to the Voice Controller. The Voice Controller’s needs are being indicating in order to make the selection easier among the speech services. Once the selection happens, the chosen service is going to be the assistant of the Voice Controller in implementation. That means that a Voice Controller will get “born” through the chosen system. In this way, a lot of time is being saved and at the end the system will be enhanced with some cool features that the speech service provides by default. The implementation of the system follows the style of documentation in order to be easier, for someone who reads this paper, to build it from scratch. It involves the development of virtual components in order to get them separated, Python scripts development and development of a representation of a proper Wireless Sensor and Actuator Network by using Raspberry Pi and Arduino. The last thing that this paper provides is further research that has been done related the next steps that the voice controller should take in order to stand better as a serious system in the world of IoT. Containerized technology and Cloud systems are the main subjects for future development.
