PROFILE
Zihanjin428
Worked on the resemble-ai/chatterbox repository to deliver advanced multilingual text-to-speech features, expanding support to 23 languages including Russian and English. Focused on refining the tokenizer and correcting Russian stressor handling, which improved pronunciation accuracy and vocabulary coverage. Enhanced the codebase with a modular pipeline in Python, simplifying future maintenance and enabling scalable multilingual deployment. Introduced an opt-in multilingual checkpoint, removed the alignment analyzer, and adjusted repetition penalties to improve speech naturalness and reduce artifacts. Updated documentation and onboarding materials to reflect these changes, supporting better cross-team collaboration and user adoption. Emphasized audio processing, deep learning, and natural language processing.
