Significance of Paralinguistic Cues in the Synthesis of Mathematical Equations

Published in International Conference on Natural Language Processing, 2014

Text to speech (TTS) systems hold promise as an information access tool for literate and illiterate including visually impaired. Current TTS systems can convert a typical text into a natural sounding speech. However, auditory rendering of mathematical content, specifically equation reading is not a trivial task. Mathematical equations have to be read so that appropriate bracketing such as parentheses, superscripts and subscripts are conveyed to the listener in an accurate way. In this paper, we first analyse the acoustic cues which humans employ while speaking the mathematical content to (visually impaired) listeners and then propose four techniques which render the observed patterns in a text-to-speech system.

Technology for the Visually Impaired


Gave a talk on the current state of assistive technology for the visually impaired, the challenges and the possibilities to the workshop participants at the Engineering the Eye workshop organized by the Camera Culture Group, MIT Media Lab and LV Prasad Eye Institute.



JAWS and Assistive Technology in Apple Products


Organized a one day workshop in collaboration with Frontline Eye Hospital, Chennai on assistive technology. This was an introductory workshop focused on spreading awareness and demonstrating the possibilities assistive technology opens up. The target audience were parents with children with visual impairments, rehabilitation trainers, and persons with visual impairments.

Computer Training in Assistive Technologies


This was a 7 day workshop organized in collaboration with Frontline Eye Hospital, Chennai. The goal was to train participants with the use of assistive technology to perform basic tasks like word processing, basic accounting, email, recreation, etc.
