Short Biography

Greetings, I'm Pradeep Rangappa, hailing from Bengaluru, India. I am currrently a postdoctoral researcher in the speech and audio processing group at Idiap, working under the supervision of Dr. Petr Motlicek. I have primarily worked on developing speech technologies (ASR, speaker diarization, spoken language identification and sentiment analysis) in different start-ups in India and possess 3.5 years of invaluable industry experience. During my tenure as a Senior Research Scientist at Swiggy, India's second-largest online food delivery platform, I played a pivotal role in the Applied Research Team. Additionally, I've served as an AI researcher at, a startup dedicated to advancing technology solutions for the banking and insurance sectors. Before joining Swiggy, I earned my PhD from IIT Kharagpur under the supervision of Prof. K Sreenivasa Rao sir, where my research centered on integrating manner of articulation knowledge into different phases of ASR development. I always find it fulfilling to delve deep into the model's current version and conduct error analyses. This practice yields valuable clues for model improvement. On a personal note, my curiosity extends beyond technology. Recently, I've embarked on a journey to explore the art of cooking, adding a new dimension to my quest for learning. I've been consistently engaged in playing Badminton. Just recently, my wife and I celebrated our third wedding anniversary (as on 24-Aug-2023), and we are also proud parents to our daughter, Manasvi (dob: 17.11.2022).
