Abstract

This paper presents the development of an intelligent baby monitoring system for deaf parents, utilizing IoT (Internet of Things) and machine learning. The system captures the baby's cries through a microphone, processes the data in a microcontroller using MFCC (Mel-Frequency Cepstral Coefficients) and LSTM (Long Short-Term Memory) networks, and sends visual and tactile alerts to parents via a lamp and a vibrating bracelet. The proposed system achieves 100% accuracy in the tested dataset, combining a lightweight and cost-effective architecture with advanced features for embedded systems applications. Compared to existing solutions, it emphasizes accessibility and affordability, making it a practical choice for parents with hearing impairments. This solution represents a significant advancement in accessibility, reducing the reliance on expensive devices and providing greater autonomy for parents.
