("So, now that you have found your neutral vocal tract vowel, you can calculate the length of your vocal tract. Take the formula for formants (Fn =(2n-1)c/4L) and put L on the left side (L=(2n-1)c/4Fn) . For instance, F3 in my neutral vowel is 2,600 Hz, so my vocal tract is about 16.8 cm long." Gnyyy.)
