Learning that personal presence is absolutely key and utilizing vocal tones to reinforce that presence is learned early on by most of the honest-to-the-gods doms I've known over the years. Or at least that's been my experience, others may have had a different growth path. There is a certain high from seeing her eyes dilate and the nostrils flare a bit with just a few words.

Using "The Voice" (for lack of a better term) in various social situations and watching for reactions from femmes that may or may not be vanilla has been a typical fishing technique too.

However, in the interest of full disclosure; being a native southerner with that distinctive regional speech pattern I have met subs that find the "drawl" to be distracting and it doesn't work for them, much to my chagrin.
