Inventor(s) include Hambarde, Bhagyashree; Khobragade, Priya Nitin; Parkhi, Priya Narayan; Govardhan, Prashant Haridas; Gudadhe, Manish; Irkhede, Tejal; Mule, Abhinav; Dandekar, Ashish; Harde, Jayshri; and Puri, Nischal.
The application for the patent was published on March 13, under issue no. 11/2026.
According to the abstract released by the Intellectual Property India: "The present invention is related to a selective speech-to-text display system for microphone-based announcements. The system ensures only intentional microphone announcements are converted into text and shown on digital display boards. The system includes a microphone (101) equipped with a broadcast trigger that enables selective speech capture, which is processed through an audio ADC (102) and a digital signal processor (103). When the trigger is activated, the speech is routed to a speech-to-text engine (104) comprising a noise reduction unit and an ASR module for accurate text generation. The formatted text is then managed by a display controller (105), which applies visibility rules and transmits the output to one or more digital display screens (106) across designated zones. Speech spoken without activating the trigger is not processed or displayed, preventing accidental transcription. The invention enhances communication accuracy, accessibility for hearing-impaired individuals, and operational reliability in public venues."
