This is a problem; so is delay.  Speech -> phoneme -> speech will
produce much more of a delay than a simple FFT -> twiddle -> IFFT
(which is what Xbox Live and most other voice masking systems use).
Hearing your own speech with a delay is really, really
disconcerting, and conversing with a delay is as well, since it
interferes with the normal timeouts for conversational cues.  Now,
it's possible to learn to live with this, but it takes practice and
is not particularly "natural".
