Emotion-Aware Multilingual Multimodal Emergency Detection System Using Edge AI and Context-Adaptive Learning

In critical emergency situations, victims often express distress through voice, language, and physical movements rather than explicit manual actions. Existing safety systems fail to capture such multimodal and multilingual cues effectively. This paper proposes a novel Emotion-Aware Multilingual Multimodal Emergency Detection System (EMMEDS) that integrates speech emotion recognition, multilingual text understanding, motion sensing, and contextual awareness using lightweight edge AI models.

The proposed framework combines convolutional neural networks (CNNs) for audio feature extraction, transformer-based multilingual text processing, and long short-term memory (LSTM) networks for motion sequence analysis. A context-adaptive attention mechanism dynamically adjusts the importance of each modality based on environmental conditions. Unlike existing cloud-dependent solutions, the system performs real-time inference on-device, ensuring low latency and privacy preservation.

Experimental results demonstrate a significant improvement of 19% in detection accuracy and a 25% reduction in false alarms compared to traditional unimodal and cloud-based approaches. The system is highly scalable and suitable for real-world deployment in personal safety, smart cities, and healthcare monitoring.
