Voice Based Food Dispensing System

Abstract

Automation technologies are increasingly being adopted to enhance comfort, security, and accessibility in everyday environments. This study presents the design and development of a voice-enabled smart food dispensing system integrated with RFID authentication and assistive features for visually impaired individuals. The main objective of the proposed system is to provide a secure, automated, and accessible mechanism for dispensing food while supporting different user groups through multiple access methods.The system is built around a microcontroller-based architecture that integrates several technologies, including RFID modules, RF transmitter–receiver communication, GSM notification systems, and voice feedback units. In the standard operational mode, users authenticate themselves using RFID cards, allowing the system to verify identity and activate the dispensing mechanism. For visually impaired users, an assistive mode is implemented in which a portable RF transmitter carried by the user communicates with the receiver module to initiate the dispensing process automatically. To improve usability and inclusivity, the system generates audio prompts before dispensing, guiding users through the interaction process.In addition, the integration of GSM communication enables the system to transmit alerts and operational updates to caregivers or family members, enhancing monitoring and safety. System performance is evaluated in terms of authentication reliability, response time, and signal detection accuracy. Experimental observations indicate that the integration of RFID verification, wireless communication, and assistive voice interaction significantly enhances operational efficiency and accessibility compared to traditional manual or timer-based food dispensing methods.The proposed solution demonstrates how combining security mechanisms, assistive technologies, and communication networks can lead to the development of intelligent and inclusive automation systems. The design is suitable for applications in smart homes, healthcare facilities, and assisted living environments, where convenience, security, and accessibility are essential requirements
