For a song like this I found the following parameter settings and voice processing steps helpful:
SynthV:
- Tension high (0,8 - 1,0)
- Breathiness mid (0,1)
- Gender mid (around 0,2 - to avoid the “girlie”-style and get a more naturalistic voice)
DAW (Reaper):
- EQ: gain high frequencies
- careful compression
- a hint of delay/echo
- some final glitter from the exciter
Have fun!
