Device Control System for a Smart Home using Voice Commands: A Practical Case

The development of new voice-controlled home assistant devices such as Amazon Echo and Google Home has allowed the interaction between users and devices in a more human and familiar way. With this background, this project aims to use Amazon Echo, Alexa, and complementary technologies to implement a smart home environment by controlling external devices using voice commands. After designing and implementing the voice controlled smart home solution, we proceeded to measure the response time of commands to verify their applicability in different uses. The implemented solution reached the expected goals allowing an effective control of different devices from an LED light to commonly used household appliances through voice commands with a reasonable delay.
