You can control how often Google Assistant responds to your voice commands with the “Hey Google” sensitivity setting. This setting lets you choose how sensitive your device is to phrases that sound like “Hey Google” or “Ok Google.”
Sometimes, Google Assistant might activate when you didn’t say “Hey Google” or “Ok Google.” This can happen when it detects something that sounds similar. If this happens often, you can make it less sensitive.
Also, Google Assistant might not activate when you say “Hey Google” or “Ok Google,” particularly in a noisy environment. If this happens often, you can make it more sensitive.
