I'm applied global variance to a 22kHz male voice. There's some occasional clipping when using gv. Without GV the results are fine. (Without gv the min and max of the waveform are around +-20000, not far from SLT demo voice.) Have you had this clipping problem with any voices?
This is because the use of GV enhances dynamic ranges of speech parameter trajectories. It sometimes over-enhancement and causes overflow.
BTW, which are you using, hts_engine or HMGenS?
