Looking for speech synthesizer

It sounds like Humanizer over a vocoded voice.

It adds fake vowel sounds. Find a demo of the Boss VF-1 Humanizer. Tell me if you think its close.
I didn’t listen to the thing, but have had some stupid useless fun playing with Alter/Ego

Type in what you want it to say/sing, and then every time it gets a midi note, it says the next syllable at that pitch. Does a pretty good job of parsing English text, but you can also type things in (pseudo)phonetically. My kid was using it to create songs in Elvish. :)
