Hi,

    }

Actually I finished implementing the speech parameter generation algorithm considering GV for the next HTS-2.1 release.
In my implementation this part is as follows:

  for (t=1; t<=pst->T; t++) {
     B[t] = WUW[t][1]*c[t];
     for (i=2; i<=pst->width; i++) {
        if (t+i-1<=pst->T)
           B[t] += WUW[t][i]*C[t+i-1][d];
        if (t-i+1>0)
           B[t] += WUW[t-i+1][i]*C[t-i+1][d];
     }
     B[t] = WUM[t]-B[t];
  }

The first release candidate of HTS-2.1 will be available in this autumn.
