Hi, everyone:
My two cents, as someone who's tried everything, had little success, but is suddenly starting to improve:
I totally agree that we all find our voice differently. I admit I'm dubious about some of the techniques I've seen online, but I'm not going to argue with results, either.
I recently purchased the Find Your Female Voice course from Deep Stealth. The results probably aren't noticeable to anyone yet. Still, I already feel like I'm developing the muscles that we use to speak in a feminine voice.
A lot of the material is on YouTube. The entire course is available at
