Implementation of an Iot-based Environment to Control an Industrial Process by Voice Commands Using a Virtual Assistant

In recent years the use of virtual assistants has been extended in a large number of applications to provide comfort to the user. This article proposes the development of an IoT (Internet of Things) environment to control an industrial process through voice commands using these devices, where the operator can interact and control the process using his voice. In the first part, a review of works where virtual assistants are used for automation and control processes is made, then the proposed architecture is presented, where we detail the protocols and media used. Next, the development of the system and the validations carried out in an industrial environment are presented, considering its own characteristics. Finally, we detail the conclusions of the project focused on minimizing access times to a control interface, and the growing use of these technologies at different levels of the automation pyramid considering its benefits and limitations.
