Implementation of the wake word for smart home automation system

As part of the voice command system for the existing smart home automation solution, we want to build the wake word module. This module should continuously listen and process the sounds from the environment, in order to detect the pre-defined wake word. Once the wake word is pronounced by the user, wake word module should trigger the actual voice command processing, which will result in the action within the home automation system. In this paper, we evaluate the possibility of using some of the existing offline speech recognition engines for this purpose. We analyze their accuracy and performance, and set guidelines for the future work.
