ReadSpeaker is in the process of building an accessibility focused Game Engine Plugin, for
Unity and Unreal, that will provide dynamic Text to Speech at runtime. We are currently looking for a few BETA testers to give us some feedback.
To give you an idea of the functionality of the Plug-In, I have been working with the Indie Game Developer,
Soft Leaf Studios, who is building a Point and Click Adventure game called
Stories of Blossom. The game features all handrawn artwork, utilizing voice actors for game characters, and TTS audio for accessibility audio cues, audio descriptions, etc.
