Microsoft said on Wednesday it updated its privacy policy to let its clients know that it had been collecting voice data of its users with the help of employees and contractors.

A spokesperson for Microsoft said the company collects voice data to provide voice-enabled services for Skype and Cortana and sometimes uses dealers to assist in improving these services.

“We realized, based on questions raised recently, that we could do a better job specifying that humans sometimes audit this content,” the spokesperson said in an emailed statement.

The company is the latest tech giant to
acknowledge to such practices after media reports on Tuesday said Facebook has been paying outside contractors to decipher audio clips from users of its services.

“We’ve updated our privacy statement to add greater clarity and will continue to ponder further opportunities to improve,” the Microsoft spokesperson said.

Tech companies in the United States have been facing immense critique from legislators and regulators over their privacy practices.
