MUMBAI, India, Jan. 2 -- Intellectual Property India has published a patent application (202541123239 A) filed by Vellore Institute Of Technology, Vellore, Tamil Nadu, on Dec. 6, 2025, for 'lightweight voice command recognition system for space missions.'
Inventor(s) include Dr. Kalaavathi B; Mr. Risabh Sinha; Mr. Kamya Singh; and Mr. Adamya Jha.
The application for the patent was published on Jan. 2, under issue no. 01/2026.
According to the abstract released by the Intellectual Property India: "The present disclosure provides a voice command recognition system for space missions comprising a wake-word detection module configured to monitor audio input and activate speech processing upon detection of a predefined wake word, a fine-tuned neural network model trained on synthetic audio data generated from space mission transcripts with noise augmentation, the model configured to transcribe captured audio data using beam search decoding, a keyword extraction module configured to identify command-related keywords from transcribed text, and a command execution module configured to execute actions corresponding to identified keywords. The wake-word detection module utilizes a Porcupine wake-word engine with dual keyword detection capability, while the fine-tuned neural network model is based on a Whisper small architecture that employs five beams during beam search decoding and achieves a Word Error Rate of 13.61% and word accuracy of 86.79%."
