You can try to change many settings for GV in the HTS demo scripts.

  MAXGVITER   maximum number of iterations of GV-based parameter
generation algorithm (default=50)
  GVEPSILON   convergence factor for GV iteration (default=0.0001)
  MINEUCNORM  minimum Euclid norm for GV iteration (default=0.01)
  STEPINIT    initial step size (default=1.0)
  STEPINC     step size acceleration factor (default=1.2)
  STEPDEC     step size deceleration factor (default=0.5)
  HMMWEIGHT   weight for HMM output prob. (default=1.0)
  GVWEIGHT    weight for GV output prob. (default=1.0)
  OPTKIND     optimization method (STEEPEST, NEWTON, or LBFGS) (default=NEWTON)
  NOSILGV     turn on GV without silent and pause phoneme (0:off or
1:on, default=1)
  CDGV        turn on context-dependent GV (0:off or 1:on, default=1)
