Voice-Assisted Elevator Control System

Abstract

A voice-controlled simulated elevator system designed to improve accessibility for visually impaired and paraplegic users through a touchless interaction model. The system employs speaker-independent Automatic Speech Recognition (ASR) using Sphinx-4 to accurately interpret spoken commands such as floor numbers, movement directions, and door operations within an eight-floor setup. For safety and emergency handling, it integrates a Text-to- Speech (TTS) module that verifies recognized ten-digit phone numbers through voice feedback before initiating a call. Experimental evaluation shows a 97% recognition accuracy for floor selection and 90% accuracy for directional and door commands, demonstrating the reliability of real-time voice command processing in an assistive, embedded elevator control environment.
