London, May 30 : Want to have a perfect good voice? Well, then all you need to do is follow a mathematical formula that consists of a voice mixture of Mariella Frostrup, Dame Judi Dench and Honor Blackman.
The study, commissioned by Post Office Telecoms, found that the best female voice to be a mixture of Frostrup, Dench and Blackman while Alan Rickman and Jeremy Irons and Michael Gambon did best for the men.
The study was conducted by linguist Andrew Linn, of Sheffield University and sound engineer Shannon Harris, reports the Daily Express.
The pair worked out their formula based on the combination of tone, speed, frequency, words per minute and intonation.
Analysing the highest scoring voices, researchers hatched a mathematical conclusion on elements that the ideal voice should contain.
They concluded the ideal voice should utter no more than 164 words per minute and pause for 0.48 seconds between sentences. Sentences themselves should fall rather than rise in intonation.
Vocal traits associated with positive characteristics, such as confidence and trust, scored highly with listeners.
Researchers found that Frostrup speaks an average of 180 wpm and pauses for 0.5 seconds between sentences, Dame Judi talks at 160 wpm breaking off for just 0.5 seconds and Blackman articulates herself at a more considered pace of 120 wpm.
Irons talks at 200 wpm, Alan Rickman 180 wpm and Michael Gambon 160 wpm.
