About
Nuance Communications is the pioneer and market leader in AI-powered clinical documentation for healthcare, best known for its Dragon Medical speech recognition platform and the DAX (Dragon Ambient eXperience) Copilot product. Headquartered in Burlington, Massachusetts, Nuance was acquired by Microsoft in 2022 in a transaction valued at approximately $19.7 billion, integrating the company's healthcare AI capabilities with Microsoft's Azure cloud and productivity infrastructure. Nuance's Dragon Medical platform is used by more than 500,000 physicians in the United States and globally for voice-driven documentation and EHR navigation.\n\nDAX Copilot represents Nuance's evolution into ambient AI documentation, enabling clinicians to conduct natural patient encounters while the AI automatically generates structured clinical notes from the ambient conversation. Built on large language models and deep clinical NLP expertise, DAX Copilot is deeply integrated with Epic and other major EHR systems, delivering AI-generated draft notes directly into the physician's workflow. Health systems that have deployed DAX Copilot report substantial reductions in after-hours documentation time — often referred to as pajama time — and measurable improvements in physician satisfaction.\n\nAs part of Microsoft, Nuance benefits from the scale of Azure infrastructure, Microsoft 365 integration, and Microsoft's partnerships with major health systems and EHR vendors. The combined entity is positioned to extend AI documentation capabilities beyond clinical notes into clinical decision support, care coordination, and administrative automation, making Nuance DAX a centerpiece of Microsoft's healthcare AI strategy.
