Hello đź‘‹,

Thanks for visiting my page.

People usually address me as Praveen. I am currently a Ph.D. student advised by Prof. Mitesh Khapra in the Department of Computer Science and Engineering, AI4Bharat, IIT Madras. I completed my B.Tech in Computer Science and Engineering in IIT Dharwad, in 2021.

Researchđź’ˇ

I'm currently working on building Neural Speech Synthesis systems with a focus on enabling them to sound more natural, more intelligible, and have rich prosody while supporting multiple voices and styles, for the major languages spoken across India. As a first step, we open-sourced SOTA TTS for 13 Indian languages in 2023 (demo). In 2024, we focused on (i) making our models more intelligible (IndicOOV, ELAICHI) , (ii) releasing the first-ever emotion-labelled dataset (Rasa) for any Indian language, and (iii) unlocking a massive speech corpus covering over 10,496 speakers (IndicVoices-R) that enables scaling Indian TTS!
