Maybe when you issue a voice command, the assistant doesn’t recognize it for some reason. It may happen due to some bugs in the app. Otherwise, while setting up the voice sample, your voice was somehow different than your normal voice. Hence, the assistant refuses to acknowledge the Hey Google command.
The effective solution is to retrain the voice and set it up again. Here are the steps.
- Launch the Google Assistant App
- On the right-hand side, you see a symbol(it is Explore button). Tap on it.
- Then under Explore tap on your profile picture of connected Gmail Account present at the top right corner.
- From the mini menu that opens up, select Settings
- Now, tap on the Assistant tab

- Scroll down to Assistant Devices. Tap on Phone.
- In the next screen, under Voice Match tap on Voice Model

- Then tap Retrain Voice Model.
When saying Hey Google, speak it up clearly and loudly for a better understanding of the virtual assistant.

Check the Microphone
The best way to check the default microphone of your device is to use any voice recording app and record your voice. If the resulting sound is cracking or doesn’t record at all, then there is a problem in the microphone. As it is a hardware issue, I suggest you should go to the official service center and get it repaired.
On the other hand, if the microphone is okay and you can record everything well, then try the other troubleshoot I have mentioned. Sometimes, the microphone panel on your phone may have accumulated dust particles or grime. So, that could obstruct the voice input.
Normally, it can happen your phone may have fallen from your hands in some dusty place. Otherwise, a phone that is a couple of years old may face this trouble due to dust accumulation over a prolonged time. So, try to take a cloth or small brush and try to dust near the microphone panel.
Using the Correct Language to Use Hey Google Command
If you are using some kind of language that Google does not support yet, then the voice assistant will not work. So, you should set the language to the English based on your region. To check for that,
- Launch the Google App
- Tap on More > then tap Settings
- Then go to Voice. tap on it

- Under that tap on Languages
- Ensure the language is set to English.
Enable Voice Command When Using Bluetooth or Wired Headsets
Often people use Bluetooth in-ears or regular wired headphones and summon voice commands through its microphone. However, you need to enable the features for both Bluetooth as well as wired headsets, so the virtual assistant will understand the command when issued from the microphone of these devices.
- Go to Google App > Tap More
- The go-to Settings > tap on Voice

- Then under the Hands-free tab, enable the toggles beside the three available options. Those are Bluetooth Audio Recording, Allow Bluetooth Requests with Device Locked, and Allow Wired Headset Request with device locked.
