increasing naturalness of vowel synthesis
I've created a source signal from scratch using PitchTier and PointProcess for vowel synthesis.
"To Sound (phonation)" command provides a couple of parameters to manipulate the naturalness of the glottal source, and I've had some success, but would still like to increase the naturalness. My problem is that I still get this attack like onset, and the vowel sound monotonous and the voice is "tight". I think I've got the pitch contour alright, but does anyone have suggestions for what other parameters I could try (e.g. how to add some jitter), and/or what would be good values for those parameters that are available in the To Sound (phonation) command?
Thanks, and best wishes, -Jyrki
