I've only used spectogram myself. I change the display type to Scope 1 personally so it looks like a line graph.
Depected in this image is a capture of the voice of a Natal lady called Lowery Turner.
The horizontal line indicate pitch in KHz the Vertical line indicates amplitude. The red lines are between 170hz and 230hz they indicate a "catchment target" for me when I'm training Female voice (Although it is entirely possible and maybe desirable to develop a female voice that targets below the basket) and a female vocal inflection requires alot of change in pitch so above and below that is fine however when singing a flat note that is generally where you should be aiming in terms of sheer pitch increase. And I should also point out alot of those really high pitch noises above the 1khz arn't really all that audible to human hearing so really you ought to work most on the voice and structure composition between the 0 and the 1 on the horizontal axis.
however there are significant structural differences between the male and female voices besides from absolute pitch. You can have women with deep female voices.
I made this quite afew months ago my voice has improved since then this was originally for my personal records. So ignore the blue line for now.
The green line in the back of this sample indicates my male voice and was always read as male As you can see compared to the female sample provided by a natal lady The male voice possesses "lower peak" beneath the red line in addition there are many MANY more peaks and thus individual tones in a male voice than a female voice.
If you count them from the 0 to 1 khz range
Male voice = 9
Female voice = 5
(the very low peak right at 0khz sample is actually a static noise from my microphone it's always present)
If you were wondering what the blue line is that was my early attempts at a female voice it was Very high pitch and only possessed 3 tones thus sounded rather shrill. Not male but just a nasty unfufilling noise.
now it looks more like this. Sample taken today
And is structurally much similar to a natal female.
In order to emulate a female voice you need to force close part of your voice box so you artificially shorten your vocal cords.
You have got the muscles to perform this ability but it's just a matter of you learning howto do it.
Some vocal coaches recommend gargling others merely describe it as "talking from behind your male voice" I don't understand what any of that means that myself
What worked for me is I sung notes with my male voice along the scale of a piano and watched what happened in the window.
After a certain point you will notice the harmonic of your voice change the tension in your voice will disable the lower vocal registers and you will sing the high notes with your upper registers thus eliminating about half of the harmonics from your voice. Then it's a matter of feeling that tension holding it then singing the same effect down the piano keys until it becomes too stressful and your voice hurts what your trying to do is pull this effect down into a normal speaking range ie 170-230 sector after you have that you will kind of sound female however you will still have to work on speech mannerisms and inflection to spit polish up the voice aswell as increasing your stamina and comfort with it
I hope this helped I'm not a speech therapist and I've never been officially counciled by one but my voice appears to pass now I've not been He'd on the telephone any time recently and when I speak it seems to help my passablity rather than hinder it.
