You asked: Why did Google Assistant activate when I didn't prompt it?
問：我並未說出任何指令，為什麼 Google 助理會啟動？
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.”
Google 助理會誤以為你需要協助而意外啟動。舉例來說，系統偵測到近似「Ok Google」的雜音時，或是你不小心以手動方式啟動裝置時，Google 助理就可能會啟動。我們會持續努力改善服務，減少意外啟動的情況。如果 Google 助理意外啟動，你可以說出「Ok Google，剛才不是在對你說話」，Google 助理就會從我的活動中刪除最後傳送給 Google 的內容。瞭解如何調整 Google 助理對「Ok Google」的靈敏度。
