Microsoft Corp has got the approval of US antitrust for its deal to buy artificial intelligence and speech technology company Nuance Communications Inc, according to a filing made by Nuance to the government. The deal worth $16 billion, which was announced in April, came after the companies announced the partnership in 2019 to automate healthcare administrative work, such as documentation.

Nuance said in a filing to the US Securities and Exchange Commission on Friday said that the deadline for the US government to oppose the deal had expired on June 1. That termination “satisfies one of the conditions to the closing of the merger,” the company said in the filing. A Microsoft spokesperson said in a statement that the deal was undergoing regulatory reviews in other jurisdictions and was intended to close at the end of 2021.
