Xiaomi’s modern smartphones have powerful computing power that allows not only running apps, but also recognizing human speech in real time. Turning on voice control turns the device into a personal secretary capable of finding information, setting alarms and managing a smart home without touching the screen. However, the standard MIUI shell or the new HyperOS often comes with preset settings that can block assistants from working to save battery life.
Users often confuse the built-in service from Google and the proprietary Mi Assistant, which is activated by default in Chinese firmware versions. For most device owners in the CIS, the first solution is critical, since it is deeply integrated into the search engine ecosystem and understands context better. The activation process requires several sequential actions in the system menu, which we will discuss in detail below.
And you have to keep in mind that the quality of the recognition is directly dependent on the quality of the Internet connection and the correct settings of the microphone. Without an active connection to the Wi-Fi network or mobile data, full use of speech recognition is impossible, because the processing of requests takes place on remote servers. Let's look at a step-by-step algorithm that will help you set up this feature in a few minutes.
Differences between Google Assistant and Mi Assistant
Before you start setting up, you need to be clear about what tool you’re dealing with. Xiaomi devices can coexist two different modules, each with its own features and use cases. Global firmware typically focuses on Google products, while Chinese (CN ROM) aggressively promotes its own development of the company.
Google Assistant is a cloud-based service that knows your habits, calendar, and location. It can answer complex questions, manage third-party apps, and translate speech into text in instant messengers. Its main competitor within the Xiaomi ecosystem is the Mi Assistant (or Xiao AI), which is sharpened to control the hardware of the smartphone itself and the smart appliances of the brand, but does not cope with Russian language and local services.
⚠️ Warning: Try to activate Mi Assistant on global firmware without additional manipulation (region or installation change) APK) Most often leads to a broken interface or persistent server errors.
For the average user who needs to dictate a message on WhatsApp or ask for the weather, the best choice is the solution from the search giant. It is already built into the Android system and does not require the installation of additional software, just wake it up correctly in the settings.
Activate Google Assistant through system settings
The first and most reliable way to run the functionality is to go to the native settings of the operating system. The interface may vary slightly depending on the version of Android and the MIUI shell, but the logic remains the same: you will need to open the main menu and find the section responsible for system services.
Follow the path: Settings → Google → Settings for Google apps → Search, Assistant and Google Lens → Google Assistant. This is the control center for all settings. If you don’t see the “Google” item in the main settings, it may be hidden or disabled by the device administrator (relevant to the enterprise versions).
Inside the menu, look for the "Assistant" tab and make sure the switch is active. This is where the service is initialized. The system can request permission to access the microphone and the history of the actions, which is necessary for the teams to work correctly.
☑️ Verification of activation
Once the base switch is turned on, the service is considered active, but it does not yet know how to respond to voice commands without further calibration. The next step will be to set the activation trigger so that the phone listens to you on demand.
Setting up the phrase “OK, Google” and Voice Match
A key feature that turns a smartphone into a smart conversationalist is voice activation. Voice Match technology allows the device to recognize the voice of a specific owner, ignoring extraneous sounds and commands of other people, and it also adds a level of security, since personal data (calendar, messages) will be available only to you.
To set up, go back to the assistant menu and select Hey Google and Voice Match. Turn on the "Hey Google" option. The system will prompt you to say "Ok Google" or "OK Google" several times to create a voice cast. Do this in a quiet room, holding the phone at a normal distance, as if you were talking to the person.
- 🗣️ Say the activation phrase clearly and with normal intonation 4-5 once upon request of the system.
- 🔒 Enable the option "Unlock with Voice Match" if you want to open your phone with your voice (not working on all models).
- 🌐 Make sure that English and Russian are selected in the Languages section if you plan to use mixed commands.
It’s important to understand that to run background wiretapping, a phone must have access to a microphone even in sleep mode.Some aggressive Xiaomi energy saving algorithms can block this process, so it’s a good idea to add Google’s service to the battery exclusion list.
Why can't the phone hear the command?
Setting up the assistant call button
Voice control is convenient, but sometimes faster, to call the assistant mechanically, with a single tap. There are several ways to do this in modern versions of MIUI and HyperOS, and you can combine them for maximum convenience. The standard method has long been held the power button.
To activate this feature, go to Settings → Additional Features → Power button. Here you will see the option "Call Voice Assistant at 0.5 sec retention." The default option may be Mi Assistant, but when you click on this option, the system will prompt you to choose your preferred service. Select Google from the list.
An alternative method is to use gestures. In Settings → Additional Features → Guest management, you can assign a finger to the bottom of the screen to call an assistant, which is especially convenient on large-diagonal smartphones, where it is difficult to reach the switch button.
| Activation method | Where to set up | Difficulty | Convenience |
|---|---|---|---|
| Long pressing of the power button | Additional functions → Including button | Low. | High. |
| Voice command | Google → Assistant → Hey Google | Medium | Maximum. |
| Gesture in the corner of the screen | Additional functions → Gestures | Medium | Average. |
| A widget on the desktop | Widget menu → Google | Low. | Low. |
The choice of method depends on your personal preferences, some people are used to the physical button, others are more important than Hands-free mode, the main thing is not to assign the same action to different functions to avoid conflicts.
Solving problems with microphone and access
Even after you set it up correctly, you might find that the phone sees a command but doesn't execute it or writes, "Something went wrong." Most often, the problem is permissions. Android has a strict control over access to the microphone, and sometimes, after updating, those rights are reset.
Go to Settings → Apps → All Apps → Google. Find App Permissions and make sure that the Microphone is allowed at all times (Allow Always). If you do not allow it, the assistant will not be able to physically hear your request.
⚠️ Note: If you use third-party launchers (Nova, Lawnchair), standard gestures and buttons may not work.
Another common problem on Xiaomi is power saving mode. The system can kill Google's process to save charge. Go to Settings → Battery and Performance → App Activity Control, find Google and select "No Limits." This ensures that the assistant is always ready to go.
💡
To check the microphone, open the recorder and record a short piece of speech. If the recording is silent or intermittent, the problem may be in the hardware or protective film covering the microphone hole.
Using an assistant to manage a smart home
One of the strengths of Xiaomi's ecosystem is the ability to control a smart home through voice. If you have lamps, sockets, robot vacuum cleaners or brand air purifiers, they can be linked to a Google account.
The linking process is as follows: in the Google Home app, click Add Device, select Works with Google, and find the list of Mi Home. Once logged in to your Xiaomi account, all your devices will appear in the list of available to manage.
- 💡 The command "Switch on the light in the living room" activates a smart lamp.
- 🧹 The phrase "Start cleaning" will send a robot vacuum cleaner on a mission.
- 🌡️ The "What's the temperature in the room?" search will show the sensor data.
This feature requires a stable internet connection and proper account linking, and make sure that the region in the Mi Home app and Google account matches, otherwise devices may not appear in the list.
💡
Integration with Google Home allows you to control hundreds of Xiaomi devices with one voice command, turning the smartphone into a universal home control panel.
