I appreciate your comment ma, notably some people are very reserved and happen to naturally possess low tones, high tones could also be an influence probably the person sells in a market and is very used to using hightones, such a person could work on factors that influences her to speak that way e.g changing environments, or associating more with people who are less reserved if you possess low tones, all the same, since this post isnt intended to pressure anyone to change her body make, i belief there is beauty in diversity of personality whether high or low tone as well as beauty in elegance.
