press space, press up arrow to render again, you can only type one word, wait a second and it will play your word. this is phonetic so type words how they sound. I'm working on making a better voicebank, fixing rendering bugs and making rendering higher quality, and adding pitches and UI which will come last. This does not simply just have a huge voicebank of words, I have actually recorded many sounds for a voicebank eg: ah, b ch, eh, I, and it knows how to use those sounds, for proof look in the code. For pitches every 10 pitch is one half step, pitch starts at 0 which is C.
