This study describes the design of a low-cost voice recognition-based home automation system that allows
physically disabled individuals with paraplegia or quadriplegia (who are unable to move their limbs but are
able to speak and listen) to control a variety of household appliances and raise their bed using voice
commands based on their comfort and needs. A voice recognition module, an Arduino Uno microcontroller,
a relay circuit, and an adjustable bed make up the suggested system. Before the speech recognition module
can be used to recognize commands, it must be trained. When the voice instruction is successfully
recognized, the Arduino uses the relay circuit to drive the appropriate load. Depending on the user's comfort
and requirements, the bed elevation can be adjusted in three different ways. Additionally, the voice
recognition module's accuracy is evaluated under various circumstances. The functions of the suggested
system are validated by the experimental results. The findings demonstrate that the system can effectively
support individuals with physical disabilities without the need for outside assistance.
