Developed a real-time Online Punctuation Model for the k2-fsa/sherpa-onnx repository, focusing on enabling real-time punctuation processing for online workflows. Leveraged C++ and Node.js, utilizing the node-addon-api to integrate the new functionality and introduce a dedicated online punctuation class. Expanded and refined test coverage, including renaming tests for clarity and updating continuous integration workflows to ensure both online and offline punctuation tests run reliably. The work emphasized robust API development and thorough testing practices, with no major bug fixes during the period. This feature improved punctuation capabilities and enhanced release readiness by strengthening quality gates and CI reliability.
