I agree with everyone else. I would record her clean and add the
effect after I had recorded her voice clean--and I would get several takes of her saying the lines..perhaps some in different ways if possible.
Unless you have a specific
effect you know very well for settings and mix and eq, you will probably want to experiment and try variations or changes to fit her vocal inflections and vocal dynamics of the words as she speaks them...so this way you have a clean voice to try things out on to adjust later in post or try different blends on. Also--some effects that alter the
pitch or detune can have some muddled or unexpected sounds come out when it comes to
sibilance or certain inflections in how words can be said--you don't want to record that and not be able to work with it..this happens especially when you are detuning a voice lower in
pitch which sometimes can slow down or blur the enunciations....yet another reason you want a clean sample to make adjustments on to find the right balance...
Its good you don't want to try and do this live for the show--that can be quite a pain and issue sometimes and lead to unexpected issues.. For example--years ago I got this one gig as a favor to friend and had to make a 10year old sound like the 'great and powerful oz' in
Wizard of Oz once....and we tried it live during the show first night and the kid got far more excited and acted with far more enthusiasm and vocal change during the show then he did in rehearsals when we tested, EQ'd and set it to the directors desire etc--so his energy change and over-enthusiasm to say the lines mucked up the whole
effect..and this can happen with almost any actor. The energy of a show can change things in delivery. The great and powerful Oz sounded like the adults on a Charlie Brown Xmas were channeling Liberace....wah wah waah wah..but...much higher...and it got more laughs then oohs and aaaahs. So after that I recorded him clean, added the
effect post and adjusted to redub it for final--and it was a playback they mixed in for show.. MUCH better...and channeled some of teh
effect to the subs and it got the Ooohs and Aaaahs it should have. Sure I could have recorded him with the
effect in rehearsal--but having the option to make adjustments and try different things out on a clean voice is giving you the most options possible...
JMO....
