Welcome!

Hello there! I am Anupama Chingacham, a doctoral student in the Department of Computer Science at Saarland University, Germany. In collaboration with my Ph.D. advisors, Prof. Dietrich Klakow and Prof. Vera Demberg, my current research focuses on using paraphrases to improve speech perception in noise. I am very honored to have received a Best Student Paper Award at INTERSPEECH 2021. Previously, I did a research internship at Loria (CNRS), obtained an MSc from the University of Lorraine (France) and an MSc from Vellore Institute of Technology (India).

My current research aims to build better solutions for noise-adaptive spoken dialogue systems that are more considerate to the difficulties of human listeners in noisy conditions. I am also keen on understanding the limits and possibilities of employing Large Language Models (LLMs) to generate text with non-textual attributes (eg: audibility), especially in low-resource settings.
