Elevator systems are central to modern smart buildings, and recent innovations aim to make them more intuitive, safe, and inclusive. Traditional models that rely on manual control panels often limit accessibility for users with physical or visual impairments while also presenting safety concerns in crowded or high-traffic environments. To overcome these challenges, this study developed an intelligent elevator system that combines voice recognition for hands-free operation with ultrasonic sensing for obstacle detection at the doors. A prototype was designed and tested under varying ambient noise conditions and distances to assess recognition accuracy, wake-up responsiveness, and door safety performance. Results indicated strong system reliability, achieving up to 97 percent recognition accuracy at 1m in quiet conditions and maintaining effective responsiveness across stationary and babble noise environments, while ultrasonic sensors consistently detected human presence to prevent accidental entrapment. These outcomes confirm that the integration of voice and sensor technologies not only enhances convenience but also strengthens safety and accessibility. In conclusion, the project demonstrates that an intelligent voice-controlled elevator with sensor-assisted doors is both practical and reliable, making it a valuable solution for high-rise residential, commercial, and institutional buildings seeking to align with the principles of smart, inclusive, and safe infrastructure.
