Worked on enhancing the documentation for mathematical expression support in Speech Service SSML within the MicrosoftDocs/azure-ai-docs repository. Consolidated and expanded guidance to clarify the use of math domain tags for plain text, MathML for structured content, and pronunciation rules in SSML, while ensuring casing and grammar consistency. Leveraged Markdown for content updates, applied technical writing best practices, and aligned documentation quality with Acrolinx recommendations. Integrated direct links to release notes to improve traceability and onboarding for developers. Used Git-based workflows to deliver seven commits, resulting in clearer, more maintainable documentation and improved guidance for developers working with SSML and MathML.
