Google Assistant might activate when you didn’t intend it to, because it incorrectly detected that you wanted its help. For example, your Google Assistant might activate when there’s a noise that sounds like “Hey Google” or you manually activate your device accidentally. We’re constantly working to reduce unintended activations. If Google Assistant accidentally activates, you can say “Hey Google, that wasn’t for you,” and your Google Assistant will delete the last thing it sent to Google from My Activity. Learn how to adjust how sensitive Google Assistant is to “Hey Google.”
