Voice assistants could guess what someone is typing

摘要

VOICE assistants can detect typing on nearby devices, which could potentially be used to work out what a person is writing on their phone from up to half a metre away. Ilia Shumailov at the University of Cambridge and his colleagues built a machine-learning system that could recognise the sound of tapping on a touchscreen and combined it with other artificial intelligence tools to see if they could determine what people were typing.
