Enable Hidden Text-to-Speech Voices in Windows 10

Microsoft Windows 10 comes with two text-to-speech engines or voices which vary for different language versions of Windows. For example, the US English version of Windows 10 comes with Microsoft Zira and Microsoft David voices. These voices can be used in Microsoft apps and desktop applications. But Microsoft also uses two separate voices for Cortana which again vary for various language versions of Windows. In case of US English version of Windows 10, Cortana uses Eva and Mark voices. These voices are not available for any other application except for Cortana itself. But with a little modification of the Windows Registry you can enable these voices for all the other applications as well.

In order to enable these hidden TTS voices for all the applications in Windows 10, you have to add a few entries to the Windows registry. To make things easier, you can just  download enable-eva-mark-voice-windows10.zip, extract the contents to a folder and double-click on the REG files inside. The Eva Voice Windows 10.reg file enables the Eva voice and the Mark Voice Windows 10.reg enables the Mark voice in Windows 10.

  1. Hello,

    I know this worked prior to 1703, but it doesn’t appear to work after the update? Any idea if this should work post 1703 or how to enable the same functionality?

    Thank you for the post!
