Microsoft announced Monday that it is purchasing AI firm Nuance. In a blog post, the company highlighted how this increases its progress in the cloud healthcare space. It’s also notable as Nuance’s technology was the foundation for Siri.

Microsoft’s acquisition of Nuance builds upon the successful existing partnership between the companies that was announced in 2019. By augmenting the Microsoft Cloud for Healthcare with Nuance’s solutions, as well as the benefit of Nuance’s expertise and relationships with EHR systems providers, Microsoft will be better able to empower healthcare providers through the power of ambient clinical intelligence and other Microsoft cloud services. The acquisition will double Microsoft’s total addressable market (TAM) in the healthcare provider space, bringing the company’s TAM in healthcare to nearly $500 billion. Nuance and Microsoft will deepen their existing commitments to the extended partner ecosystem, as well as the highest standards of data privacy, security and compliance. “Nuance provides the AI layer at the healthcare point of delivery and is a pioneer in the real-world application of enterprise AI,” said Satya Nadella, CEO, Microsoft. “AI is technology’s most important priority, and healthcare is its most urgent application. Together, with our partner ecosystem, we will put advanced AI solutions into the hands of professionals everywhere to drive better decision-making and create more meaningful connections, as we accelerate growth of Microsoft Cloud in Healthcare and Nuance.”
