Be careful not to over-inflect during a speech. Too much modulation produces an unpleasant effect of artificiality, like a mature matron trying to be kittenish. It is a short step between true expression and unintentional burlesque. Scrutinize your own tones. Take a single expression like "Oh,no!" or "Oh, I see," or "Indeed," and by patient self-examination see how many shades of meaning may be expressed by inflection. This sort of common-sense practise will do you more good than a book of rules. _But don't forget to listen to your own voice._
