Low-Cost Android App Based Voice Operated Room Automation System

Smart home appliances with a host of different control features have become a popular research area. Most of these systems are expensive and require a complete replacement of the existing equipment. The proposed method will be able to modernize the existing home appliances and add voice command feature to almost any legacy home appliance at affordable prices. This framework will be very helpful for the needs of elderly and handicapped patients due to its minimalistic technological knowhow requirements. The system operates on an android phone, connected over Bluetooth to a local home automation node. The app recognizes speech commands and transmits it to the node. Based on the devices connected to it, the node searches for keywords in the command and takes a control action.
