Modern Xiaomi smartphones have powerful functionality that is often hidden behind layers of the shell MIUI or HyperOS. One of the most useful tools available to owners of Android devices is the voice assistant from Google. Many users buy a phone without even knowing that they can control the gadget with a voice just by saying a magic phrase.
Activating OK Google turns your device into a personal secretary, so you can run apps, send messages, navigate routes, and search the Internet without touching your screen, which is especially useful when you're busy or driving, but on Chinese brand devices, this option is not always on by default due to the regional settings.
In this article, we will take a look at how to properly activate voice control, adjust your voice recognition, and solve typical problems. We will look at the nuances of working on different versions of the operating system and explain why sometimes the assistant is silent despite the correct commands. Follow the instructions to unlock the full potential of your device.
Preparation for activation of voice assistant
Before you start setting up, you need to make sure that your smartphone is technically ready to work with advanced Google services. First of all, check if the current version of the Google application is installed. Often it is the outdated version of the application that blocks the appearance of the necessary settings in the menu. Go to the Play Market store and update all the system components of the search engine.
The second important aspect is Internet access, and voice commands are processed on the company's servers, so you need a stable connection to set up and train your voice model in the first place, and it's best to use a Wi-Fi network to avoid interruptions in the process of writing reference phrases.
It's also worth checking the language of the system. For the Russian-speaking team to work correctly, OK Google, the interface of the smartphone should be Russian or English, and if you have a rare localization, the functions may not work correctly.
- 📱 Make sure you have a Google account on your phone.
- 🌐 Check for a stable connection to the Internet.
- 🔄 Update Google and Google Assistant Apps through Play Market.
- 🗣 Install Russian as the main language of the system.
Remember, the microphone must be in good working order and not covered with a protective film or a cover, and the quality of recognition depends on the purity of the sound that enters the system.
Enabling a feature in the Google app
The main setup takes place directly inside the search engine ecosystem. Open the Google app on your Xiaomi smartphone. Notice the profile avatar in the top right corner of the screen, which is where all the key settings are hidden.
Click on the profile icon and select Settings. In the menu that opens, look for the Google Assistant section. This is where all the levers of smart functionality are concentrated. If you see Google Assistant, it means that the service is active, but it may need to be customized.
💡
If the “Assistant” item is not on the menu, try clearing the Google app cache through Settings. → Annexes → All applications → Google → Clear the cache.
Go to the All Assistant settings tab, and here you are interested in the Hey Google and Voice Match section (in Russian localization it can be called "OK, Google" and "Voice Match"). Switch the slider to the active position. The system will ask you to confirm your account ownership.
Once the slider is activated, the phone will offer a learning procedure, which is a critical step, because it allows the algorithms to remember the timbre of your voice and reduce the number of false positives on other people's commands.
- 🔍 Open the Google app and click on the profile avatar.
- 🛠 Go to Settings. → Assistant → All settings of the Assistant.
- 🎙 Activate the “OK Google” switch in the Voice Match section.
- ✅ Take the phrase training procedure for better recognition.
Once you've successfully completed the setup, you'll hear a confirming sound, and the screen will show a message that the assistant is ready to go, and from now on, you can call it at any time.
Set up Voice Match and Teaching Phrases
Voice Match is a voice biometrics technology that allows Xiaomi to distinguish between the owner and strangers, which is important not only for security, but also for personalizing the delivery of information, such as reminders from a calendar or to-do list.
As you learn, the system will ask you to say a few standard phrases, like "OK Google" and "OK Google, turn on your flashlight." Speak clearly, at a normal pace and with the tone you plan to use most often. No need to shout or whisper.
If you use your phone frequently in noisy places or in silence, you can try retraining in different acoustic conditions, which will improve the reliability of the response. Voice Match also allows you to add multiple voice models if you have multiple family members using the phone.
⚠️ Warning: Don't use voice recordings taken on voice recorders to bypass learning systems. Google algorithms can detect synthetic origin of sound and block the feature for security reasons.
Once you have set up, you should check the function, try calling the assistant from 2-3 meters away without touching the screen, and if the reaction is instantaneous, then the microphone sensitivity and the Voice Match setting are done correctly.
- 🗣 Speak the phrases clearly and at a normal conversational pace.
- 🏠 Conduct training in a quiet room without background noise.
- 🔄 Add voice models to other users if necessary.
- 📢 Check the team from different distances after setting up.
The recognition quality depends not only on the software settings, but also on the hardware of a particular Xiaomi model. Flagship models usually have more advanced noise-cancelling microphones.
Activation via lock screen and off screen
One of the most convenient features is the ability to call an assistant when the screen of the smartphone is turned off, which allows you to instantly set a timer, find out the weather or call without unlocking the device.
In the Google Assistant settings menu, look for "OK, Google" Recognition, and it'll be "Switched off" or "Blocked screen" and activate it, and the system will warn you that this may increase battery consumption slightly, as the microphone will be constantly in the background in standby mode.
☑️ Checking the work from the off screen
Note that on some versions of the MIUI shell, an aggressive energy saving system can kill background listening. To avoid this, go to the battery settings, search for the Google app and set Unlimited mode.
Also make sure that the lock screen allows the assistant to display the answers, otherwise the phone may vibrate or make a sound, but not show a visual response, which creates a feeling of malfunction.
| Screen status | Required settings | Battery consumption |
|---|---|---|
| Screen on. | Basic activation | Minimum |
| Screen locked | Permission in the Assistant settings | Low. |
| Screen's off. | Background listening + battery settings | Medium. |
| Do not disturb mode. | Additional authorizations | Depends on the regime. |
Using a command from the screen off greatly improves the comfort of your smartphone. You will no longer search for a phone in your pocket just to know the time or the exchange rate.
Setup on different versions of MIUI and HyperOS
MIUI shells and the new HyperOS have their own resolution management features. In recent firmware versions, Xiaomi has tightened control over app access to the microphone. If after all the settings, OK Google doesn't work, the problem may be global permissions.
Go to Phone Settings → Apps → All Apps. Go to Google Apps. Click App Permission. Make sure that the microphone is allowed at all times ("Allow Always"), not just while you're using.
Why are the settings reset after rebooting?
Also check your privacy settings. In Privacy Protection → Microphone, the access indicator can be activated. Make sure Google is not blocked from the list of apps that are not allowed access.
HyperOS devices have a deeper integration with the smart home, so make sure the region in your Google account settings matches the region specified in your phone’s settings (usually this affects the availability of some features, although basic voice search should work everywhere).
⚠️ Note: If you are using global firmware on a Chinese device (or vice versa), some Voice Match features may not be available due to regional restrictions on Google servers.
Owners of older Xiaomi models (such as the Redmi Note 8 and older) may need more time to respond, in which case it is worth turning off the interface animation in the “Developers” menu to speed up the response to voice commands.
Solving Typical Problems and Errors
Even with the right setup, users may find themselves in a situation where the smartphone stops responding to a command, most often due to a Google app update or a change in Android system security policies.
If the reboot didn't work, check if the Power Saving mode is on. In this mode, the system turns off background listening to the microphone to extend battery life. Turn off energy savings or add Google to the exceptions.
Another common problem is conflict with other voice assistants, such as Mi AI, which is pre-installed on Chinese firmware versions. Make sure that Google Assistant is the default default assistant. You can check this in the Settings menu → Applications → Application Management → three dots in the corner → Default Apps → Assistant.
💡
90% of problems with the broken “OK Google” are solved by resetting the settings of the Google application or reinstalling its updates.
In some cases, cleaning the app data helps. Go to Settings → Apps → Google → Memory → Clean. After that, you will have to re-train Voice Match, but this often “cures” software glitch.
- 🔋 Turn off the energy saving mode to check the work.
- 🔄 Reinstall Google App Updates via Play Market.
- 🤖 Check which assistant is selected by default in the system.
- 🧹 Clear the cache and data of Google apps if nothing helps.
If the problem persists for a long time and is not solved by standard methods, it may be a hardware malfunction of the microphone.
