In a blog post Thursday, Google confirmed it employs people world-wide to listen to a small sample of recordings.
The public broadcaster’s report said the recordings potentially expose sensitive information about users such as names and addresses. It also said Google, in some cases, is recording voices of customers even when they aren’t using Google Assistant.
In its blog post, Google said language experts listen to 0.2% of “audio snippets” taken from the Google Assistant to better understand different languages, accents and dialects. “This is a critical part of the process of building speech technology, and is necessary to creating products like the Google Assistant,” it said.
