Very neat new TTS engine, works in a wide variety of languages (e.g. English UK/US, German, Afrikaans) and with different inflections and voices.
Also works locally and (once the generator is downloaded the first time) super fast (on my pc takes around 10 seconds for generating a minute of speech in German). Since you will usually have shorter speech snippets will work even faster.
Can be used in client/server setup, through the local cli or as part of the mycroft engine. Neat!
