ProVoice is a free chat client developed by the Microsoft team at Microsoft Research.
ProVoice was originally launched as a commercial project, but has since been upgraded to be fully open source.
ProChat was originally developed for a Microsoft Office suite called Outlook Express.
ProTextEdit, ProVoice’s sister software, was developed by Microsoft Research, and was initially developed as a Windows Phone 8.1-based collaboration tool.
ProVanity, Pro Voice’s other sister app, was designed as a chat assistant for Microsoft Outlook Express, and is now a paid Windows 10 app.
The app store listing on ProVoice says that ProVoice will now include a new version of ProVoice 2.3, a “modern version of the core app,” that includes a new set of enhancements.
Pro Voice 2.2 was released in October 2017, and it was described as “an update to ProVoice 1.0 that improves the reliability and performance of Pro Voice.”
It also includes new functionality for voice calls, text chat, voice dictation, and multiple accounts.
It’s also listed as having an update to the ProVoice Web app.
ProVoice 2 is available on both the Windows Phone Store and the Windows Store for $9.99, and the Pro Voice Pro app is available for free for 10 days.
