Home automation and the concept of Internet of Things (IoT) have been existing for more than a decade, with billions of devices are connected to the internet. The conventional home automation system allows users to control household appliances such as lights, airconditional, surveillance camera, etc. via smartphone applications, webpages and control panels. One of the major drawbacks is with the operation efficiency, where people would still need their hands on the physical interfaces to excess the system. It could be quite inconvenient for specific groups such as the elderly and disabled people, who will not benefit much from such systems. In light of this, the project proposes a methodology and design of a voice-controlled environment with emphasis on speech recognition and voice control based on Amazon Alexa and Raspberry Pi. In this design, office users can easily control their office appliances with voice commands, the model can be implemented for smart home users as well. The proposed voice-controlled system comprises eight main features: 1) Control of wired electrical appliances; 2) Control of Radio Frequency (RF) and Infrared (IR) appliances; 3) YouTube connected entertainment system; 4) Digital memo; 5) Face recognition access control feature; 6) Security surveillance; 7) Room occupancy detection; 8) Telegram-based voice-controlled text messaging. The proposed system not only save time but also bring convenience to people.
