Modern Xiaomi smartphones have powerful functionality that is often hidden behind layers of MIUI or HyperOS interface. One of the most convenient management tools is Google Assistant, which is able to execute commands without touching the screen. However, standard system settings sometimes block the ability to activate voice, which causes confusion among users.
In order for your device to respond to the phrases "OK, Google" or "Hey Google", you need to go through several stages of checking the settings. This is not just the activation of a single button, but a comprehensive setup of the microphone, permissions and system priorities. In this article, we will discuss all the nuances that will help you control your phone exclusively with voice.
You will learn why the feature may not work even after turning on, how to configure the voice recognition of a particular user and which Xiaomi models support constant listening.
Checking basic requirements and system version
Before you start complex manipulations, make sure your device is technically ready to work with advanced Google Assistant features. Not all budget models have a dedicated processor for processing neural networks, although the software feature may be available. It is important that the current version of Google service is installed on your smartphone.
Open the Play Market and find the Google app. If the Update button is available, make sure to do this. Older versions of the app may not contain the necessary modules to recognize Hotword. Also check that the system's interface language is Russian or English, as these are the main support languages.
⚠️ Note: On some global firmware MIUI For Chinese versions of devices, voice-activated functionality may be limited to Google account regional settings.
Make sure you have a stable internet connection. Voice commands are processed on the company's servers, so without a network, activation is impossible. Check whether Wi-Fi or mobile traffic is working before you start setting up.
Setting up Google App and Activating Hotword
The main setup takes place directly inside the search engine ecosystem, not in the phone’s system settings. Open the Google app on your Xiaomi and tap the profile icon in the top right corner. In the menu that appears, select Settings and then go to Google Assistant.
You need to find the tab "All Assistant settings" or immediately see "Hey Google and Voice Match." That's where the voice response switch is hidden. Activate the "Hey Google" slider. The system will ask you to say a few phrases to train your voice model.
- 🗣️ Say clearly the phrase “OK, Google” or “Hey Google” four times as the system asks it to remember the timbre.
- 🔒 Make sure that the “My Voice Recognition” function is activated in the same menu, this will improve security.
- 🌐 Check if the correct language is selected in the Languages section, otherwise the assistant will not understand the command.
Once the Voice Match training is successfully completed, the system will confirm readiness. Now, with the screen unlocked, the assistant must respond to the name. However, on Xiaomi devices, additional settings are often required to work in sleep mode.
Configure access to the microphone and permissions
HyperOS and MIUI are known for their strict security policies, which often block the background microphone for third-party applications.If Google Assistant is on but not responsive to voice, chances are the system is barred from constantly accessing the microphone.
Go to Settings → Apps → All apps. Find the Google app (not Chrome, but Google with a colored G.) and go to App Permissions and select Microphone. Set the value of "Allow Always" or "Allow Use in the Background".
⚠️ Warning: Without permission to access the microphone, voice activation will only work when the Google app is open on the screen.
Also worth checking the battery settings. The system can "kill" the listening process to save energy. In the app settings menu, find "Control Activity" or "Start Up." Make sure Google has a "No Limits" limit on its service. This is a critical step for stable operation.

Standby mode and constant activation
One of the most useful features is the ability to call an assistant when the screen is off. On many modern Xiaomi models, this is done through Google Fast Pair technology or built-in processing chips. However, if you have a mid-range or budget model, this feature can be called Waiting Mode.
In Google Assistant settings, find the device or screen section, and it might have the option "Enable when your phone is connected to charging." This is a popular use case: the phone is on the base, the screen is on like a clock, and it responds to commands. To do this, the phone must be on charge.
If you want the assistant to work at all times, even with a dead screen, it requires significant resources. Only flagship models with Snapdragon processors of the 8-series and higher often have hardware support for constant listening without heavy battery consumption. On other devices, the battery can run out faster than usual.
| Function | Screen's off. | Screen on. | Requirements |
|---|---|---|---|
| Basic activation | No. | Yes. | Internet |
| Standby regime | No. | Yeah (Always On) | Charging, OLED screen |
| Continuous audition | Yes. | Yes. | Flagship processor |

Use of buttons and alternative methods
If voice activation ("OK, Google") is unstable or in a noisy room, it's convenient to use alternative call methods. Xiaomi owners can configure the Assistant call via a power button or swipe from the corner of the screen, which is often faster and more reliable than waiting for a voice response.
To set the power button, go to Settings → Additional Features → Button (or “Appoint the Power button”). Select the option “Google Assistant” for long press (0.5 seconds). Now, when holding the button, voice input will be called, and you can immediately say the command.
- 📱 Swipe from the corner: in the settings "More" →"One-finger control can be assigned to swipe from the bottom corner to launch the Assistant.
- 🎧 Headphones: Many Xiaomi and Mi True Wireless wireless headphones allow you to call the assistant with a triple press or hold of the sensor.
- ⌚ Watch: If you have a Mi Band or Watch, set up a notification or button to quickly call an assistant.
The use of physical buttons is especially important when the phone is in your pocket or bag, and you can reach the device, press the button, and ask a question without looking for the unlock screen.
💡
Use the "Write a note" command immediately after calling the assistant to quickly save the thought without unlocking the phone or opening the applications.
Decision: Assistant is silent or answers incorrectly
A common problem with Xiaomi users is that the assistant activates visually but doesn't hear the command or responds with a "I can't do that yet" stub. This is often due to conflicting language packs. Make sure that the Assistant settings in the "Languages" section are the first language you speak.
If the problem persists, try clearing the app cache. Go to Settings → Apps → All Apps → Google → Storage and click Clear Cache. Don't worry, it won't delete your account details, but it will reset temporary files that may have been corrupted.
⚠️ Warning: Clearing the data (not the cache) will reset the Voice Match settings, and you will have to retrain the system to your voice.
Also check if Do Not Disturb or Silent mode is on. In some system configurations, this may suppress voice response, although the visual interface will work. Rebooting the device also often resolves temporary malfunctions in the microphone module.
💡
If voice control stops working after a system update, check the microphone resolutions first – MIUI updates often reset them for security reasons.
Comparison with Mi AI and choice of assistant
Xiaomi smartphones often pre-installed its own voice assistant Mi AI (or Xiao AI). Users often confuse them or try to activate Mi AI commands for Google. It is important to understand the difference: Google Assistant is better integrated with mail, maps and calendar services, and Mi AI penetrates deeper into the system settings of the phone itself.
You can use both assistants at the same time, but you need to clearly pronounce the name to activate the voice.OK, Google will launch a search engine, and Xiao Ai Tong Hue (or Russian adaptation, if available in the region) will run a native assistant.For most users in the CIS, Google is preferable because of a better understanding of the Russian language and context.
In conclusion, the right voice control setup makes your smartphone a powerful tool, and don't be lazy to go through the voice learning and permission tuning phase, because these are the steps that ensure 90% of the success of your future use.
