I've searched the web and any available websites, but couldn't find anything about MicroType and speaking. However, if you have a modern operating system, Windows features an Accessibility area where you can turn on Narrator and other helping tools for audio support.
Implementing accessibility settings in an application could be sometimes very hard, therefore you can simply use what Windows offers. To see the exact options, go to Start > Settings or Start > Control Panel and locate the Accessibility settings.
