Activation of voice control on Xiaomi smartphones often becomes an asterisk task, especially given the specifics of the MIUI shell or the new HyperOS. Unlike pure Android, where the assistant works out of the box, the ecosystem of the Chinese manufacturer requires careful configuration of several system parameters for the correct operation of the function "OK, Google".
The main difficulty lies in the aggressive optimization of the battery and conflicts between the system services of Google and the built-in assistant XiaoAI. Users often face a situation where the microphone does not hear the command, or it is simply ignored by the background processes.
To get started, you'll need a stable Internet connection and a Google account added to the system. Without authorization from the search giant, activation of the function is technically impossible. Next, we'll take a look at all the nuances of the setup so that your smartphone is always ready for dialogue.
Basic activation through the Google app
The first and most important step is to check the settings inside the Google app itself, and this is where the main switch for listening to the keyword phrase resides, and it often happens that after resetting or updating the system, this option is automatically disabled.
Open the Google app on your Xiaomi device. Click on the profile avatar in the top right corner and select Settings. In the menu that opens, look for Voice (or Voice Control) and that's where the master switch "OK, Google" is hidden.
Once you turn on the slider, the system will ask you to go through the learning process, which is a critical step, because the algorithm has to remember the timbre of your voice, you have to say the standard phrases several times in silence, and don't ignore this step, otherwise the recognition rate will be low.
- 📱 Open the Google app and click on the avatar.
- 🗣️ Go to Settings. → Voice input → Okay, Google.
- 🎤 Take the process of learning voice recognition.
- ✅ Make sure the switch is activated and lit in blue.
If you don't hear a confirming sound or vibration when you say a phrase after you turn on, check if the system's sound is off. Sometimes the activation works, but the user doesn't get feedback thinking the function isn't working.
Permits and access to the microphone in MIUI
MIUI is famous for its strict security policies, which often block the background of applications, so that “OK, Google” is running constantly, even when the screen is off, you need to give the application extended access rights.
Go to your smartphone settings and find the Apps section. Select All Apps and go to Google in the list. Go to Other Permits, where you want to allow access to the microphone in Always or Allowed mode.
⚠️ Note: If the permission settings are “Forbidden” or “Only during use”, the voice assistant will not be able to activate with the screen turned off.
Next comes the important step of setting up autostart, and then you can find the "Start" option in the same menu and activate it for the Google app, which will allow the service to start immediately after you turn on the phone without waiting for the user to act.
It's also worth checking for location access. For many voice queries to work correctly (e.g., "where is the nearest refueling"), the system needs access to geodata. Set "Allow all the time" for maximum functionality.
☑️ Checking Permits for Google
Battery optimization and background work
Aggressive energy saving is the main enemy of voice assistants on Xiaomi devices, which can kill Google’s process, considering it a resource eater, if it hangs in the background for a long time waiting for a command.
To prevent this, go to Settings → Apps → All Apps → Google → Activity Control. Select No Limits. This is a critical setting that prevents the system from forcibly stopping the process.
In some versions of HyperOS, the path may be slightly different: Advanced Settings → Battery → Application Energy Saving. Search the Google list and make sure that there is no “Save Energy” checkmark.
| Setup parameter | Recommended value | Impact on work |
|---|---|---|
| Auto-start | Included. | Starting the service at the start of the OS |
| Activity monitoring | No restrictions. | Prevents closure in the background |
| Working in the background | Permitted. | Allows you to listen to the team without a screen |
| Saving energy | Off. | Reduces the frequency of microphone checks |
After making the changes, it is recommended to restart the device, which will allow the system to apply the new rules of energy saving and correctly initialize the background services of Google Play Services.
Why is MIUI closing apps so aggressively?
Conflict with XiaoAI and language settings
Global firmware versions often conflict between the built-in Chinese assent XiaoAI and Google Assistant, and if the phone has activated a Chinese region or language, the native assistant may be given priority.
Check your language settings. Go to Settings → Additional → Language and Input. Make sure your primary language is Russian or English. Chinese is best removed from the list or lowered if it is not used.
It is also important to check the settings of the Google Assistant itself. In the Google app, go to Settings → Assistant → Languages. Your primary language should be selected here. If you add multiple languages, try leaving only one for testing.
- 🌐 Install the main language of the system - Russian or English.
- 🇨🇳 Remove Chinese from the list if you don’t use Chinese features.
- 🗣️ In the Assistant settings, select one primary language.
- 🚫 Turn off the XiaoAI call button if it conflicts with Google.
Sometimes cleaning up Google's data helps, and it caches and compulsorily restarts all sync services, and you can do this from the Apps menu → Google → Memory → Clear all data.
Setting up the call button and hot keys
For ease of use, you can set up the assistant call not only with voice but also with buttons. On Xiaomi smartphones, this is especially true, since voice activation sometimes may not work in a noisy room.
In the Google Assistant settings, look for the All Assistant Settings section → Assistant Tab → Phone. You can activate the Home button (if it's touch-sensitive) or the side power button to call the Assistant.
If you use gesture navigation, hold the screen angle (depending on the navigation settings) for a long time to call the menu. Some versions of MIUI have a separate setting called Press and Hold Power button, which can be reassigned to Google Assistant instead of XiaoAI.
💡
Use the command "Hi, Google" instead of "OK, Google" if the standard phrase is not recognized well. This alternative greeting often works more consistently in the Russian-speaking segment.
Also worth mentioning is the Locked Screen Access feature, which means making sure that the security settings and the Assistant settings allow access to personal results and smart home management even when the phone is locked.
Resolving frequent errors and problems
Even after you set it up properly, you can have some failures, and one of the common problems is that the microphone is busy with another app, and if you're talking on a messenger or a voice recorder, Google can't take over the audio control.
Another reason is an outdated version of Google or Google Play Services, so go to the Play Market, find the Google app, and click Update. Often, the bugs are fixed with the security patches.
⚠️ Note: If you use third-party launchers (Nova, Apex), voice activation from the screen turned off may not work.This is an Android security limitation, not a Xiaomi bug.
If you completely refuse, try to delete Google app updates (via app settings) and then update it again through the store.This helps to reset erroneous configuration files that may have been corrupted when you upgrade your system.
💡
90% of voice search problems on Xiaomi are solved by setting “Activity Control” to “No Limits” and allowing you to work in the background.
Additional teams and opportunities
Once activated successfully, you can see the world of voice control, so you can not only search for information, but also control the settings of the phone, such as "Put the flashlight on" or "Put a screenshot" works instantly.
And what's useful for drivers is that they say, "Build a route to..." and the phone automatically starts Google Maps and paves the way, which is safer and faster than typing an address on the go.
Don’t forget multimedia. The “Live Music,” “Louder,” and “Next Track” commands work with most of the popular players and streaming services installed on your Xiaomi.
