How do I learn to sing in a feminine voice so I can sing females vocals for my songs?

[vurt]

Step back and let an Alison Moyet take the mic

Why? If he wants to sing, let him sing and go some other thread if you find that so annoying.

of course.
but, he has to learn that some choices aren't available to him, theres only so far you can change a voice, even with a great singing coach. eg: there was no way any amount of training would allow barry white to sing like the bee gees or vice versa.

obviously, we have technologies that can go some of the way, im sure most would agree they don't sound natural though.

so if he wants a natural sounding female vocalist, theres only really one option.

(perhaps not alison, she might be busy or too expensive)

Identify as a female while your singing. Forget about science or logic. Just go with your feelings.

And I already thought this threat was about sex change

"Threat"? Freudian slap!

Of course believability will always depend on the singer. Anyway...
The best plug-ins for this are the harmonizers from Eventide, imho.
I'm consistently amazed by how good they are. Specifically Octovox and Quadrovox.

You need to go on a diet consisting mostly of soy products.

There is a technique called "countertenor voice" or "countertenor singing":

Of course, there's also the reinforced falsetto, which is the technique used by Barry Gibb, if I'm not mistaken:

And then there's this guy...

You can have a lot of fun with Waves Ultrapitch.
Make chorus, or just move your voice up an octave, and alter formant filter over to femail side.
Do falsetto, like BeeGee's, and yet more femail sounding.

Ultrapitch is part of Gold bundle, which is $99 for 30+ plugins - it's a steal.

Use a vocaloid, I believe there's someone on here that can guide you

Stupidest thread ever.

Internet, please never die!

To answer OP's question: you can't.

No. He can (may be).

This male vocal is almost female. Listeners (who don't know) sometimes confuse it with a female vocal.
