Why is voice command not working with Android Auto?

Android Auto is an app developed by Google to allow Android smartphone users to easily and safely access their smartphone apps and functions through the dashboard screen of a compatible vehicle. Android Auto enables the use of voice commands to interact with apps to make calls, send messages, play music, get directions, check the news, and more hands-free while driving.

One of the key features of Android Auto is its voice command functionality utilizing the Google Assistant to control apps and vehicle functions through natural speech. When connected to a vehicle, the microphone enables drivers to issue voice commands without having to use touch controls on their phone. This allows drivers to keep their hands on the wheel and eyes on the road for a safer driving experience.

Microphone Issues

One common reason for voice commands not working properly with Android Auto is a physical issue with the microphone itself. The microphone used for Android Auto is built into the vehicle’s infotainment system or into an Android Auto compatible stereo head unit. If the microphone stops working due to hardware failure, physical damage, or a loose connection, voice commands will fail to register properly.

Signs of a microphone malfunction include the voice command button not activating Android Auto’s listening mode, commands not registering at all, or commands only working intermittently. You may need to have your vehicle serviced to diagnose and replace a damaged microphone component. Some troubleshooting steps you can try include checking microphone connections, testing with different phones, resetting the stereo, and updating the stereo firmware if available. But a full repair may be necessary if the microphone itself is broken.

App Permissions

One common reason Android Auto voice commands may not be working is if the microphone permission has been revoked for the Android Auto app. According to a post on the Android Auto support forums, some users have found that the microphone permission gets reset to “Only while the app is in use” instead of “All the time”. This prevents Android Auto from accessing the microphone when running in the background.

To fix this, go to your phone’s Settings > Apps > Android Auto. Tap Permissions and make sure Microphone is set to “Allow all the time”. This will allow Android Auto to access the mic even when not actively being used. Be aware that having mic access enabled all the time can raise privacy concerns, so only do this if you fully trust the Android Auto app.

Bluetooth Connectivity

One common issue with Android Auto not recognizing voice commands is problems with the Bluetooth connection between the phone and car (source). The phone needs to be wirelessly paired to the car’s infotainment system via Bluetooth in order for the voice recognition feature to work properly.

However, sometimes Android Auto may fail to connect via Bluetooth or the connection gets broken. This wireless pairing issue will prevent the microphone on the car from picking up voice commands and transmitting them back to the phone. There are a few potential causes of Bluetooth connectivity problems:

  • Issues with the pairing process – Make sure Bluetooth is enabled on both devices and try repairing them.
  • Range/interference – Bluetooth has limited range so distance from the infotainment system can cause problems. Other wireless signals can also interfere.
  • Software bugs – Android Auto or the car software may have bluetooth bugs that require an update to fix.
  • Incorrect setup – The phone may not be properly configured as the Bluetooth audio source for the car.

If Android Auto voice commands are not working, the first troubleshooting step is ensuring the phone and car are properly paired via Bluetooth and that the connection remains stable while using Android Auto (source). If Bluetooth issues persist, checking for software updates and rebooting both devices can help resolve connectivity problems.

Background Noise

Excessive ambient noise in the vehicle can prevent voice commands from properly registering with Android Auto. Sources of background noise like engine noise, road noise, music, and conversations from passengers can make it difficult for Android Auto to isolate and interpret your voice commands (https://www.reddit.com/r/AndroidAuto/comments/qo1592/severe_white_noise_on_phone_calls).

Android Auto relies on the microphone built into your vehicle or connected device to pick up your voice. Noisy environments can overwhelm the microphone and make your voice get lost among other sounds. This is especially problematic in older vehicles without adequate sound dampening or noise cancellation abilities.

Some users have reported increased background noise and inability to use voice commands after Android Auto or phone software updates, indicating that changes to noise filtering algorithms may be to blame in some cases (https://android.stackexchange.com/questions/252336/android-auto-noise-during-phone-call).

If voice commands fail consistently in noisy conditions but work fine when it’s quieter, background noise is likely the culprit. Trying commands when the vehicle is stationary with the engine off can help isolate background noise issues.

Network Connectivity Issues

One common reason Android Auto voice commands stop working is if there are network connectivity issues preventing proper syncing between your Android phone and car display. Android Auto relies on having a strong cellular data or WiFi connection to communicate between the devices.

If you are in an area with poor cell reception or a weak data connection, this can interrupt Android Auto causing features like voice commands to fail. The connection needs to be strong enough on both devices to maintain a stable handshake. Similarly, if you drive into a dead zone where you lose data, it can temporarily disrupt Android Auto.

To troubleshoot, first check that you have a strong cellular data connection on your phone in the problem area. Try toggling Airplane mode on and off to reset the connection. Or connect the phone and car display to a strong WiFi network instead. If the problem persists, it likely points to a larger connectivity issue in that location rather than a problem with Android Auto itself. You may need to avoid using voice commands in known dead zones. See this guide for more network troubleshooting tips.

Software Updates

Android Auto and the operating system on your Android phone receive periodic software updates that can sometimes introduce bugs affecting voice commands. An Android Auto or phone OS update may inadvertently break functionality that was previously working. For example, several users reported loss of voice commands after updating to Android 12 on their Samsung devices. Try rolling back the Android Auto app to a previous version or factory resetting your phone to undo any problematic updates. Keep software up-to-date, but watch for release notes or user reports indicating an update may have caused regressions. If a particular update seems to break voice commands, you can try uninstalling it or rolling back until the issue is addressed.


One common reason Android Auto voice commands may not be working properly is that the voice recognition is having trouble understanding certain languages or accents. Android Auto’s voice recognition relies on the Google Assistant, which supports over 30 languages, but some accents can still be challenging for the technology to interpret.

If your primary language is set to English but you have an accent, or you’re trying to use Android Auto in a language other than your phone’s default, the system may struggle to understand your voice commands. You can try changing the Assistant language in the Android Auto app settings or on your phone’s Google Assistant settings to see if another language works better.

Some users have reported mixed success getting Android Auto to understand different languages or accents reliably, even after changing settings. While Google is continually working on improving voice recognition accuracy for more languages, accents and dialects, some limitations may remain.

Checking Android Auto and Google Assistant language settings and trying both your native language and English can help in some cases. But the technology may still have difficulty with certain accents or languages it is less exposed to in training data. Additional troubleshooting tips if the issue persists include speaking slower and clearer, or using button controls instead of voice where available.

Hardware Limitations

One potential reason for voice commands not working properly with Android Auto is if the hardware in your phone or car stereo system is too old or underpowered to handle voice processing efficiently. Voice recognition requires significant processing power, especially for interpreting natural language commands.

According to Google’s Android Auto support page, Android Auto requires a phone running at least Android 8.0 Oreo. Older phones may lack the hardware capabilities to handle voice commands seamlessly. The car stereo also needs sufficient processing power and memory, especially if it is more than a few years old.

Underpowered hardware such as low-end processors or insufficient RAM in older phones and car stereos can lead to latency or failure to process voice commands. Upgrading to newer smartphone and car stereo models with faster processors and more memory can help overcome hardware limitations related to voice recognition. Proper microphone setup and reducing background noise can also help voice commands work better on strained hardware. But ultimately the voice processing capabilities are dependent on the hardware specifications.

Troubleshooting Tips

If voice commands are not working properly in Android Auto, there are some common troubleshooting steps to try:

First, make sure the microphone is clean and not blocked. Dust, dirt, and debris can prevent the microphone from picking up your voice commands accurately. Clean the microphone with a soft brush or compressed air.

Next, check that the Android Auto app has permission to use the microphone. Go to Settings > Apps > Android Auto > Permissions and enable the microphone access.

It may also help to reboot your phone and car stereo system. Turn both completely off and restart them. This will clear any software glitches that may be interfering with Android Auto.

Check for Android and Android Auto app updates and install any available updates. Updates often contain bug fixes and performance improvements.

Make sure your phone’s Bluetooth connection to the car is strong. Bluetooth connection issues can disrupt voice commands. Move the phone closer to the car stereo, remove obstructions between the two devices, and pair the phone with the car stereo again if needed.

Reduce background noise in the car when using voice commands. Noise from music, open windows, passengers talking etc. can impact recognition of voice commands.

Finally, if issues persist, you may need to reset Android Auto. This will clear app data and reset settings which may resolve voice command problems.
