[gnuspeech-contact] a Kelly-Lochbaum TRM

[Andras Kadinger]

I listened to the gnuspeech demos a number of times over the years. I 
was always fascinated by the pleasant intonation and formant 
trajectories - but was quite put off by the unnatural, formant 
synthesizer-like timbre.

To rekindle the love, I hacked up a Kelly-Lochbaum TRM in Java:

The toy UI I have on top of it is the "Four Tube Vocal Tract Models of 
Vowels" from 
http://clas.mq.edu.au/acoustics/frequency/vocal_tract_resonance.html 
just to have an simple yet phonetically somewhat meaningful way of 
playing with it to get a rough idea of the wovel quality to be expected 
from such a model.
