Your voice reveals more about you than you realize. To the human ear, your voice can instantly give away your mood, for example—it’s easy to tell if you’re excited or upset. But machines can learn a lot more: inferring your age, gender, ethnicity, socio-economic status, health conditions, and beyond. Researchers have even been able to generate images of faces based on the information contained in individuals’ voice data.
