Needless to say, one of the surest signs a man has confidence and a certain level of grit is his tone of voice. Mine has always seemed to be high pitched and nasally. I got damn tired of it and began to experiment with different breathing techniques and slightly manipulating my vocal chords, but it just came across as fake and forced. My uncle had noticed and imparted some golden advice. "You gotta speak from your balls. Not your belly or your diaphragm. Imagine they're your lungs." When I do, it helps me keep in the RP frame of thought. I hold my chin a little higher and I'm able to command respect from both what I'm saying and how I say it. Just thought I'd pass on this little tip because it's helped be so much. And in case there are others having issues sounding like a queer Bitch and not a fucking man.
