Windows 10 has the new voices Microsoft Kangkang Mobile and Microsoft Yaoyao Mobile, but they are not available in text-to-speech software. Is it possible to unlock the new voices?
By default, the Microsoft mobile voice (also known as "OneCore") is locked for using in text-to-speech software via SAPI 5. You can unlock it with a simple registry tweak. Download the archive, extract the file for your language and for your version of the operating system ("mobile_x86.reg" for 32bit and "mobile_x64.reg" for 64bit), click the right mouse button on the file's name and choose the context menu item "Merge". The Microsoft mobile voice will appear in the list of the available voices in Balabolka.
Alternatively, the utility SAPI Unifier can be used for the same purpose.
