Voice feminization, essentially.
This is my personal roadmap for voice feminization, modified a little to also work as a guide. The focus is mostly on mileage and familiarity, so expect perfecting these concepts to take a long time.Keep in mind that I'm no professional by any means, and that all these concepts were developed by people much more experienced and talented than I am.With that out of the way, you may proceed.
General rules
For every sound task, explore further and experiment with the sound (over a long period of time), to gather the necessary familiarity. Make sure to actually speak sentences, instead of just making vowel sounds over and over.
Train your ear. If you're targeting a specific quality, learn what it sounds like, and look for it in others' voices.
Breathiness and constriction are not allowed, and you must speak at a conversational volume.
Record and analyze clips of your own practice, to both train your ear and check for mistakes.
Your sounds must all be pure and extremely comfortable, to the point where you can confidently speak in said voice for over an hour without any strain whatsoever.
If a sound causes pain or discomfort, stop immediately, and search for an alternative way to make the same sound without said discomfort.
List of topics
Weight control
Size control
Fullness and further exploration
Personality-expressing features
Weight
Seek Clover's video for demonstraions and exercises.
Make a Patrick Star (yawny, light, lazy) or Mickey mouse (high-pitched, breathy, falsetto-ey) sound
Make sure your voice lacks a "rumble" (This is an indication of high weight)
Remain extremely relaxed and pure
Experiment with changing volume at a constant weight (by changing pitch)
Explore, experiment, and acquire familiarity
Some more weight explorations can be found in the clip collection.
Size
Begin by listening to Selene's size clip.
Move from a large sound into a small sound (you can do it as a slide or do it in steps)
Explore changing weight (starting heavy or starting light)
Try to aim for a younger-sounding voice
Avoid knodel
Avoid any and all feelings of strain
Remain completely pure and non-breathy
Get very familiar over a long period of time
Fullness and
further exploration
Start by watching the TransVoiceLessons fullness video.
Learn about deandrogenization
Create a full-masc sound (heavy, large)
Create an overfull sound (heavy, small)
Create a full-fem sound (light, small)
Create an underfull sound (light, large)
Acquire extreme familiarity with those four main fullness types
"Slide" between different zones of fullness
Adduction work (expansion of one's pitch range) can be worked on using the clips below.
Personality-expressing features
Information about this topic is a little scattered - you'll find a lot of it on the Speech section of my reddit post.This section focuses on ear training.
Understand the theory behind why children of different sexes do not usually sound the same, despite their shared lack of sexual development
Listen carefully for the differences in pronunciation between men and women
Notice vowel shifts, vowel replacement, and vowel stress
Analyze voices and determine whether their manners of speech are more typically masculine or typically feminine
Notice how pronunciation differs across regions of the world
This section focuses on experimentation and mimicry.
Explore said qualities in your own voice
Imitate other voices, while remaining mindful of the aforementioned concepts
Compare your recordings to the recordings of the desired voice, and analyze thoroughly
At this stage, you may stylize your voice by changing the accent, getting a little larger, a little heavier, etc. It's strongly recommended to be very familiar with the hyperfem space before doing this, though.
Conclusion
Absolutely none of this would have been possible without the tremendous hard work of Clover Grigsby, Zheanna Erose, and Selene Da Silva. Huge thanks, from me and many others.If you ever feel like you need more information, check out my collection of Selene's clips, which also includes advice on normalization, a topic I did not cover in this guide. The Online Vocal Coach server is also great for asking questions and attending free lessons.And that's about it for this guide, good luck.
