American technology company Google says its contractors listen to recordings of what people say to artificial intelligence system Google Assistant. The company admitted that people can review those recordings after some of its Dutch language audio clips were leaked to the public. Google product manager David Monsees wrote about the leak in a recent blog post. He said the company is investigating their release. Belgian broadcaster VRT NWS got hold of more than 1,000 Google Assistant recordings. It noted in a story that some recordings contained sensitive personal conversations, as well as information that identified the person speaking. Google said the recordings do not identify user account information. It added that contractors who listen to the audio are told not to take notes of background conversations.
