The development of the Internet of Things (IoT) technology has a positive impact on human life. A smart home is one of the IoT technology applications that facilitate human activities. The problem of physical abnormalities is a matter of limited activities for disabled people. This paper proposes a design of IoT-based smart home application with a remote control device that developed using voice commands for disabled people. Smart home control systems help disabled people to control their home electrical devices such as television (TV), lights, and fans using only voice commands without moving to turn on or turn off electrical equipment. The voice recognition on electrical equipment is using the Google Assistant's application on smartphones. The Google Assistant application will accept voice commands when the pronunciation is correct. Voice commands on IoT-based Smart Home are more simple to apply, without typing text messages. Users get convenience compared to using text. The signal strength of an Internet connection will create a useful performance device at the Response Time of Google Assistant, Response Time of System Processing, activating and deactivating Electrical Equipment. We expect that this device could be more useful to help disabled people interact with their environment by utilizing IoT technology facilities.
