Hearing my voice again totally blew my mind

AI tech is giving people their lost voices back. We chat to Yvonne Johnson, who has motor neuron disease. She's lost much of her ability to speak. But artificial intelligence is helping Yvonne to be heard again, with her own voice. Also this week: we discuss AI and the price of memory chips with a big computer manufacturer. And video gaming is booming in Africa. Presenter: Shiona McCallum Producer: Tom Quinn (Image: A photo of Yvonne Johnson. She is smiling directly at the camera. Credit: Portrait Of A Voice.)
