Making purchases with your voice is convenient, but it’s far from secure. Google is attempting to change that when using Assistant by introducing an optional voice verification test.
As The Verge reports, the new security feature relies on Google Assistant’s Voice Match and it’s being rolled out slowly as part of a limited pilot program to test how well it works with smart speakers and smart displays. The Voice Match training feature was updated recently to include phrases so that Assistant could more accurately determine who is issuing commands.
