The Power of the Human Voice
How we use our voice and how our voices are used.
The human voice is a thing of great power and persuasion; we use it to speak to one another, to sing and cry, to laugh and scream. But our voices - which are as ancient as humanity itself - are also at the forefront of the very latest developments in technology. Increasingly, our voices activate machines, are used to prove innocence or guilt in criminal trials, to provide a means of digital communication for people with voice disorders. With Suzy Klein to discuss the human voice are the cognitive psychologist Diana Deutsch the acoustic, forensic and voice analysis expert Professor Peter French and the opera singer Anna Devin.

Describing her voice and how she uses it to sing.
Professor Peter French is the UK’s most experienced expert in the field of forensic speech and acoustics and works at the Department of Language and Linguistic Science, University of York and is chairman of J P French Associates. He has worked in the field for 30 years.
Prof. French has provided evidence in thousands of cases across the whole range of forensic speech and audio. His evidence has been for UK Crown Courts and courts across the world, including: Australia, Canada, Ireland, Germany, Ghana, Gibraltar, Hong Kong, Mauritius, The Netherlands, New Zealand, Singapore and the United States of America. He has worked on cases heard by the International War Crimes Tribunal and the Bloody Sunday Inquiry in the UK. He’s interested in how we can break down the component parts of the human voice in order to recognise who is speaking and talks about developments in voice recognition and analysis.
Diana Deutsch is a British-American perceptual and cognitive psychologist, born in London, England. She is currently Professor of Psychology at the University of California, San Diego, and is one of the most prominent researchers on the psychology of music. She is probably most famous for the musical and auditory illusions that she’s discovered which include the octave illusion, the scale illusion, the glissando illusion, the tritone paradox, the phantom words illusion, the speech-to-song illusion and the cambiata illusion, among others.
She also studies the cognitive foundation of musical grammars, the ways in which we hold musical pitches in memory, and the ways in which we relate the sounds of music and speech to each other. In addition, she is highly acclaimed for her work on absolute pitch, or perfect pitch, which she has shown is far more prevalent among speakers of tone language. She talks about the importance of pitch in the human voice and how our voices have evolved.
Irish soprano Anna Devin is fast becoming established as one of today’s brightest young sopranos, highly praised for her strong stage presence and vocal versatility. She sings a wide repertoire of both sacred and secular works, and she has appeared as part of the BBC Proms with the Hallé Orchestra under Sir Mark Elder in Parsifal, the London Handel Festival, Brighton Early Music Festival, Belfast Festival as well as with the RTÉ NSO and Ulster Orchestra.
Anna is dyslexic and talks about how this has affected her approach to singing, especially in foreign languages and more generally how she thinks about her voice.
