Google Assistant Not Responding to ‘Hey Google’: How to Fix It
Here’s everything you can do if the Google Assistant voice command is not working.
1. Enable Hey Google
If you haven’t enabled the ‘Hey Google’ command detection, you will not be able to launch Google Assistant every time you say the phrase out loud. Here’s how you can do it.
Step 1: Open the Google app. Tap on your profile icon in the top right corner. Tap on Settings.


Step 2: Tap on Google Assistant. Select ‘Hey Google & Voice Match’.


Step 3: Turn on the toggle for Hey Google.

2. Check Microphone Permissions
If the Google app does not have access to your microphone, it will not detect your voice and you will find that ‘Hey Google’ is not working. Here’s how you can check microphone permissions.
Step 1: Long tap on the app icon. Select the info button.
Step 2: Tap on Permissions.


Step 3: Tap on Microphone. Select ‘Allow only while using the app’ to provide permission.


3. Force Restart Google App and Restart Phone
Force closing the Google app shuts down all related processes, including any bugs affecting voice detection. Once you open the app once again, it is unlikely the bug will appear again and you can use the ‘Hey Google’ command without problems.
Step 1: Long tap on the app icon. Select the info button.
Step 2: Tap on Force Stop. This shuts down the Google app.


Additionally, you can also restart your phone to fix the issue. Since the Google app is a built-in application, restarting your device and all the system processes afresh can get rid of any bugs.

4. Check Internet Connectivity
Make sure your Android device is connected to the internet via Wi-Fi or cellular data. Further, make sure you have an active internet plan. If you haven’t enabled offline voice detection, ‘Hey Google’ will not work to launch Google Assistant without the internet.
