Virus bootcamp on vocoder?

It seems for years now that the vocoder section of all of access's synths don't really have much inspiring information about programming. A bootcamp on the TI's vocoder would be greatly appreciated.

Yeah good call! Never managed a decent vocoder patch yet... Seems unfinished to me. 8|

While toying with the vocoder and vowel filter, I couldn't help but notice that the modulated speech lacks "oomph". Anatomically speaking, the resulting vowels lack depth, as if they are produced by a person with no sinus cavities. This leads me to believe that what's missing is a degree of self oscillation, or resonance. Another useful feature found in other vocoders but missing from the Virus is a high-pass through, which takes the top end of the modulating speech (usually cutoff frequency can be controlled) and adds it to modulated sound. This saves the need to add white noise to the oscillators in order to get the sibilants right.
