EmotiVoice AI: a Multi-Voice and Prompt-Controlled TTS Engine. Open source and free, for text-to-speech audio generation…
The most prominent feature is emotional synthesis, allowing you to create speech with a wide range of emotions, including happy, excited, sad, angry and others.
An easy-to-use web interface is provided. There is also a scripting interface for batch generation of results.
Thus, if you can get past the fiddly command-line install and Python dependencies (there’s at present no simple standalone Windows installer), then this may well be of interest to 3D and 2D animators, as well as creators of TTS voice-overs for YouTube videos etc.
