MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202521123326 A) filed by Sonali Singh; Chanchala Kamat; and Prof. Navita Shrivastava, Rewa, Madhya Pradesh, on Dec. 7, 2025, for 'multimodal emotion recognition system using facial, speech, and heart-rate signals.'
Inventor(s) include Sonali Singh; Chanchala Kamat; and Prof. Navita Shrivastava.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses a multimodal emotion recognition system (100) configured to assess human emotional states by jointly analysing facial expressions, heart-rate variability signals, and speech characteristics. The system includes a Facial Data Acquisition Unit (101), a Heart-Rate Sensing Unit (102), and a Speech Acquisition Unit (103), each linked to corresponding processing modules (104, 105, 106) that extract modality-specific emotional features. A Fusion Module (107) integrates the processed outputs to generate a unified emotional assessment, enhancing robustness compared to unimodal systems. The architecture enables real-time evaluation by combining behavioural, physiological, and acoustic indicators, thereby improving accuracy under varying environmental and user conditions. The system provides a reliable framework for mental-health monitoring, adaptive human-computer interaction, and emotion-aware applications across portable devices, wearable platforms, and intelligent monitoring systems."
