As long as you get to where you want to be in the end, no approach is wrong.
I've hit another "breakthrough" of sorts with my voice, though entirely by accident. A few months ago, I was sick with something for a few days, experiencing a single symptom each day. One day was a runny nose, the next extreme nasal congestion, the next a sore throat. But after that, I had a day where my throat felt closed off somehow, like around the bottom half of my throat. My throat wasn't sore and my voice didn't sound affected at all until I tried to use my feminine voice.
It came out very different, sounding more natural than anything else I'd done before it. Even cooler, I could for the first time use female resonance with lower pitches, speaking with a bit of the huskiness Moonspirited mentioned. I had difficulty in keeping my voice steady because of the weirdness in my throat, but the resonance still sounded on par. However, when I go over whatever it was I had I wound up back at where I was before. . .
. . .At least until a few weeks ago. While talking to myself at home one day, I randomly stumbled upon that husky voice and immediately recognized while doing it that the sensation in my throat and in my mouth was similar to those I felt while sick before. From there, I messed with it more until I figured out how to carry that sensation over to the average female pitches. It all came together so quickly and fluidly I wondered for a moment if I'd actually wasted my money on those voice training programs.
I know I didn't, though, because without them I wouldn't have the muscle awareness or control needed to take advantage of the situation my being sick offered. (Now if only I could catch something that ultimately helps me with my intonation.
)
Whatever approach you use, know that there are several, some amateur, some professional, and some just acquired from personal experimentation, and they need not be employed to the exclusion of all others for you to be successful.
