Voice / Vocal Time Stretch Recommendation

Hey Cubasers

I’ve just upgraded from 8 to 8.5 Pro and in the studio I record mostly voice overs. I’ve noticed after updating that any form of time stretching in 8.5 adds some artificial sound. I mostly record 30s scripts and it’s only 1 or 1/2 sec that I’m time stretching. I’ve started going through the preferences but thought I would open it up to experienced user group and ask what you recommended setting is.
