Microsoft is set to add the voice assistant Cortana to the search and messages apps it has developed for its Windows Phone operating system.
The announcement was made in a blog post by a Microsoft representative, which also indicated that Cortana would be added to Microsoft Outlook.
Microsoft has said Cortana will be available to developers later this year.
Microsoft has been developing Cortana for Windows Phone since 2014, when it announced the first versions of Cortana for iPhone and Android.
The company has said that Cortana will eventually be available on all versions of Windows Phone, but only for developers who can access its API.
The Redmond-based software company will begin testing Cortana on its Windows Phones this year, the company said, adding that Cortana is expected to be available “by the end of this year”.
Microsoft is a pioneer in voice-activated assistants, and has been able to sell more than a billion phones with its voice-powered assistant since its inception in 2013.
Its Cortana app has been downloaded more than 70 million times and its support and support for voice recognition is so strong that the software company has been praised by some critics for being the most secure voice-enabled assistant.
