The ‘Perfect Voice’
Andrew Linn, a linguist at Sheffield University along with sound engineer Shannon Harris created a formula based on tone, intonation (emphasis and inflection), pace, pause (words per minute). They concluded “the ideal voice should utter no more than 164 words per minute and pause for 0.48 seconds between sentences. Sentences should fall rather than rise in intonation (inflection).
Your voice adds to your authority and credibility but also can do the opposite. It’s not hard to learn how to create your best voice, it just takes consistent practise of very simple exercises.
