Science & Natural History

Being able to speak is what makes us human.If you've ever felt the shock of listening to a recording of your own voice, you realise how important your voice is to your personal identity. We judge others - and whether we trust them - not just by their words but by the way they talk- their intonation, their pitch, their accent.Now You're Talking explores the full range of our voice - how we speak and how we sing; how our vocal anatomy works; what happens when things go wrong; and how technology enables us to imitate and manipulate the human voice. Trevor Cox talks to vocal coaches who help people to develop their new voice after a gender change; to record producers whose use of technology has transformed the singing voice; and to computer scientists who replicate the human voice in their development of artificial intelligence.Beginning with the Neanderthals, Now You're Talking takes us all the way to the digital age - with the frightening prospect that we may soon hear 'Unexpected item in the bagging area' more frequently than a friendly 'Hello, how are you?' in the street.
