AI Listened to People’s Voices. Then It Generated Their Faces.

Live Science: “Have you ever constructed a mental image of a person you’ve never seen, based solely on their voice? Artificial intelligence (AI) can now do that, generating a digital image of a person’s face using only a brief audio clip for reference. Named Speech2Face, the neural network — a computer that “thinks” in a manner similar to the human brain — was trained by scientists on millions of educational videos from the internet that showed over 100,000 different people talking. From this dataset, Speech2Face learned associations between vocal cues and certain physical features in a human face, researchers wrote in a new study. The AI then used an audio clip to model a photorealistic face matching the voice.

The findings were published online May 23 in the preprint jounral arXiv and have not been peer-reviewed. Thankfully, AI doesn’t (yet) know exactly what a specific individual looks like based on their voice alone. The neural network recognized certain markers in speech that pointed to gender, age and ethnicity, features that are shared by many people, the study authors reported. “As such, the model will only produce average-looking faces,” the scientists wrote. “It will not produce images of specific individuals.” AI has already shown that it can produce uncannily accurate human faces, though its interpretations of cats are frankly a little terrifying…”
