PROFILE
Subhankar Ghosh
Subhankar Ghosh developed and enhanced text-to-speech capabilities in the NVIDIA/NeMo repository, focusing on modularizing the MagpieTTS inference API and expanding support for longform and multilingual content. He refactored Python code for maintainability, introduced dataclasses for structured outputs, and improved evaluation metrics handling. His work included updating tokenizers for better French input processing and adding Hindi and Japanese language support with language-specific sentence splitting. Subhankar also implemented local transformer models using autoregressive and MaskGit sampling, contributed comprehensive documentation, and maintained code quality through linting and cleanup. His efforts strengthened TTS reliability, scalability, and onboarding for developers working with NeMo.
