MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202641043540 A) filed by Binu K Mathew; Kuriakose Philip; Mathews Reji; Muhammed Anees; Navya Prasad; Er. Ria Mathews; and Saintgits College Of Engineering, Changanacherry, Kerala, on April 6, for 'rasip real-time audio to sign language.'

Inventor(s) include Kuriakose Philip; Mathews Reji; Muhammed Anees; Navya Prasad; and Er. Ria Mathews.

The application for the patent was published on April 17, under issue no. 16/2026.

According to the abstract released by the Intellectual Property India: "The existing communication gap between the hearing population and the deaf or hard-of-hearing community underscores the need for an effective and real-time assistive communication system. RASIP (Real-Time Audio to Indian Sign Language), tries to solve this problem by providing a automated system for translating spoken language into its corresponding Indian Sign Language (ISL) equivalent. The system utilizes an Automatic Speech Recognition (ASR) module to process the audio, a Natural Language Processing (NLP) module to process the language, and a gestures visualization module to display the results in sign language videos. The platform uses a multi-threaded architecture that allows audio processing, text interpretation, and sign language video retrieval to occur at the same time, which enables the platform to facilitate real-time translation with low latency. By correlating the interpreted text with a predefined set of ISL gestures, the system is able to generate sign language that represents the spoken words through visual means. RASIP is also optimized to work efficiently on light platforms such as Raspberry Pi, making it an appropriate solution for use in different settings such as learning institutions, health facilities, public service facilities, kiosks, and many more. The capability of the system to combine speech recognition, language processing, and sign language generation makes it a suitable solution for closing the communication gap in a manner that is inclusive to the deaf and hard-of-hearing community."
