In this public lecture, Professor Trevor Cox (University of Salford) will discuss how the growth of tools that use voice recognition and electronic voices are influencing the acoustics of speech and what this might mean for the future. Talking and singing comes naturally to most of us so it is easy to overlook how truly remarkable the voice is. Mixing biology, physics and psychology, Trevor will explore the workings of the voice looking at accents and different singing styles. The human voice has always been in flux, but over the last hundred years or so, this has been accelerated by technology. What about the future? ‘Photoshop for voice’ has already been demonstrated, leading to a future with #FakeSpeech. Rich in sound examples, the talk will draw on Trevor’s latest popular science book, Now You’re Talking. This evening talk is organised as part of 2019 IEEE International Ultrasonics Symposium being held in Glasgow between 6 and 9 October 2019.
