Time to Explore Your Voice
Congratulations. You have learned to manipulate every single element involved in vocal feminization! Now for the fun part - you get to play around with all these knobs and dials on the control panel of your voice, and find the configuration that you like best. You get to explore the possibility space of your voice!
A great way to do this is with a mantra phrase. The idea is to say the same phrase over and over again while tweaking different aspects of your voice, so you can easily compare the sound without thinking about what you are going to say. Watch this video for an overview of the concept and some great example phrases that you can use yourself.
The "Keep It Cutesy" Mantra
Try one of my own mantra phrases, designed specifically to help you practice and get a feel for your brightest, most feminine sound: "Keep it cutesy!"
Try saying it a few times in a feminine voice, then whisper it a few times. If you break it down and stretch it out, it sounds like "keee-p ihhh-t keee-yooo-tsss-seee!" Try it.
When you say "k" the top of your tongue presses against the roof of your mouth to block off the air, and when you say "ee" your tongue drops down to let the air through. Try whispering "kee" while keeping your tongue pushed up toward the "k" position, so it moves as little as possible to get to the "ee" instead of dropping down so much. That will create your brightest possible "ee" sound.
Try saying "keep" with that bright sound - your tongue should hardly move at all. Then try saying "cute" by starting with that "kee" sound and then pushing your tongue slightly down into a "yoo" sound. Whisper it first, and then say it, moving your tongue as little as possible, so the brightness of the "kee" carries into the "yoo" because your tongue is still pushing up toward that "k" position.
Brightening Your Sibilants and Labials
Whisper "tsss" and try to move your tongue as little as possible from the "t" to the "s" sound. That will create a brighter, sharper "s" which will come across as more feminine. At the same time, keep pushing the back of your tongue up toward the "k" position to brighten it further. This applies to all your sibilants - "s", "z", "sh", "zh", "ch", "j" and so on! Then try whispering "see" - sliding from the "s" back to the brightest possible "ee" that you can make.
Now put it together. Say "cutesy" - stretch it out like "keee-yooo-tsss-seee" - first in a whisper and then spoken in a feminine voice. Say "keep" and for the "p" sound, really tighten your lips into a small but narrow opening, and keep them tight as you touch your lips together briefly for a subtle, unobtrusive "p" sound. This applies to all your labial consonants - "p", "b", "m", "w", "f", "v" and so on - and you want to keep your lips somewhat tight even for your other consonants and vowels, because it will make them brighter.
Putting It All Together
Whisper and then say the whole thing, at a pitch that is about as high as you can comfortably speak without going into your falsetto. "Keep it cutesy!" You can stretch out all the sounds to really get a feel for them and find that brightest position. As you say the vowels, practice pushing the brightness to a buzzy, brassy extreme, raising your larynx, pushing the back of your tongue up, and layering on the vocal twang to find that harsh edge.
The only thing you want to avoid is nasal resonance. So also try saying it while pinching your nose shut - it should sound almost the same, whether you pinch your nose or not. Practicing this will help you access and lock in your brightest, cutest vocal posture and pitch, just by saying the phrase!
More Mantra Phrases
Once you get comfortable with "Keep it cutesy," you can also try some other mantra phrases:
"Keep calm and carry on." This mantra phrase is similar, but with some darker vowel sounds like "ahh" in "calm" which you can practice saying while still clenching your tongue up toward that initial "k" position. There are also "r" and "l" sounds to practice brightening, again, by pushing your tongue up at the same time. Practice whispering it, stretching it out, and saying it with the brightest sound you can make.
"We're beautiful creatures." This one gives you a chance to practice bright vowels and consonants across a wider variety of sounds.
Use your selected mantra before calls, meetings, or social interactions to quickly lock in your voice and improve consistency of voice launch.
