Xiaomi’s modern smartphones are no longer just call devices, becoming powerful multimedia centers that can be controlled by a single voice. Activating this feature significantly speeds up the work with the gadget, allowing you to run applications, send messages or search for information without touching the screen. Users often look for ways to turn on voice control on Xiaomi Android to make interaction with the interface more comfortable and technological.
There are several speech recognition systems in the Chinese manufacturer's ecosystem, each with its own customization features, the Google Assistant, which is deeply integrated into the MIUI or HyperOS shell, but the company's proprietary designs are also available, and the correct microphone configuration and software permissions ensure that the system responds instantly to your commands in any situation.
In this guide, we will take a closer look at how you activate all the options available, from basic system settings to fine-tuning your sensitivity, and how to get your phone to respond to the phrase “OK, Google” even with the screen locked, and what hidden features will become available after you set up properly.
Main types of voice control in MIUI and HyperOS
Before activating, you need to understand the differences between the tools available. Xiaomi, Redmi and POCO smartphones usually have two main types of speech recognition systems pre-installed. The first and most versatile is the Google Assistant, which works on most Google-certified devices and supports Russian in full.
The second option is a proprietary solution from the company itself, Xiao AI (or Mi AI), which is sharpened to control Xiaomi’s smart home and deep integration with the shell’s system functions, but its support for the Russian language may be limited or require additional manipulations with the region. For most users, the optimal choice is a bundle of Android system settings and Google services.
⚠️ Attention: Global versions of Xiao feature firmware AI may not be available or work properly without changing the region to China.
Also, some features are OS version dependent. In the new HyperOS shells, natural language processing algorithms have been improved to recognize commands even when there is background noise. Older versions of MIUI may require clearer pronunciation and no extraneous sounds to perform tasks correctly.
Activate Google Assistant through system settings
The most reliable way to start using voice input is to properly configure Google’s built-in assistant, which requires no third-party software installation and is based on system services already present on the device, and to get started, you need to make sure that the device is logged in to Google’s account and installed all necessary service updates.
Go to the settings menu on your smartphone, and you'll need to find the system settings section or Google services section, and the path may vary slightly depending on the version of MIUI, but the logic remains the same: we're looking for account management and basic search functions.
☑️ Pre-activation check
The following is a sequence of actions that must be performed carefully:
- 📱 Open Settings and browse to Google (often at the bottom of the list or under System Apps").
- 🗣️ Select Settings for Google Apps, then go to Search, Assistant, and Google Lens.
- 🤖 Click on Google Assistant and select the Google Assistant subsection.
- 🔊 Find the Hey Google and Voice Match option and activate the switch.
Once turned on, the system will prompt you to undergo a training procedure, and you will need to say the activation phrase several times so that the voice recognition algorithms remember the timbre and intonation, which increases the accuracy of the response and reduces the number of false starts from strangers or the TV.
The important thing is to allow access to the microphone, and if the system requests permissions, you must agree, otherwise the function will not work, and in some cases, you may need to allow access to contacts if you plan to use commands to call specific people.
Configure activation from the locked screen
One of the most popular features is the ability to activate the assistant when the smartphone screen is off, which turns the device into a full voice recorder or navigator without requiring prior unlocking, but this feature consumes battery power because the microphone is in constant listening mode.
To activate this feature, go back to the Hey Google and Voice Match menu described in the previous section, where you will find the screen-locked Access (or "OK Google Recognition") switch. Once activated, the system will alert you to potential security risks, as anyone who knows your voice will be able to access some of the phone's features.
| Setup parameter | Recommended value | Impact on the system |
|---|---|---|
| "OK, Google" recognition | Included. | Allows voice activation |
| Locked access | Included. | Working without unlocking the screen |
| Personalized results | If you wish, | Use of data from mail and maps |
| Improve speech recognition | Included. | Sending records to the server for analysis |
There is also an alternative activation method, either through the power button or a special key. In new versions of the HyperOS shell, you can set up a long press of the off button or side key to call the Assistant. To do this, go to Settings → Additional → Buttons and select an action for a long press.
Why not work with the screen off?
Using Google App for Extended Teams
To get more in-depth customization and access to your query history, we recommend using a separate Google app, which serves as a central hub for managing all search and voice functions, and is where language settings, content filtering, and activity management are stored.
Open the Google app (the "G" icon) and click on your avatar in the top right corner. Select Settings, then Voice Input. Here you can:
- 🌐 Language: Make sure that you choose Russian (and if necessary add a second language for multilingual mode).
- 🎤 Voiceover: Customize the voice that the Assistant will answer you (different timbre and intonations are available).
- 📜 History: Review and delete saved voice requests to maintain privacy.
In the same section, you can have a Continuous Dialogue feature, which if you turn it on, you don't have to say "OK, Google" every time you ask, but the assistant will listen to a pause after you answer and wait for you to continue the conversation for a few seconds, which is convenient when you're making complex lists or planning your route.
⚠️ Warning: Continuous dialogue significantly increases battery consumption, as the microphone stays active longer than usual.
Problems with speech recognition and their solution
Even after setting up correctly, users may find themselves in a situation where the smartphone stops responding to commands or misunderstands them, most often the problem lies in the background processes of the Android system, which kill Google’s service to save energy. This is standard behavior for MIUI, which requires manual adjustment.
To ensure stable operation, you need to remove the Google app from the battery optimization list. Go to Settings → Apps → All apps. Go to Google list, click Power Savings and select No Limits option. This will allow the service to run in the background constantly.
Another common cause of failure is contamination of the microphone or overlapping it with a protective case. Check the bottom and top edges of the device. Also make sure that in the privacy settings (Settings → Privacy Protection → Permissions Manager) the Google app has access to the microphone.
If problems persist, try clearing the service's cache. Go to Settings → Apps → Google → Memory → Clear the cache. Don't worry, this won't delete your personal data, but it will reset temporary files that may have been corrupted.
Useful voice commands for everyday use
Once you've figured out how to turn on voice control on Xiaomi Android, you'll need to master a basic set of commands. Voice input allows you to perform complex operations in seconds. For example, the phrase "set an alarm at 7 a.m." works faster than manually searching for a watch app.
The system understands contextual queries. You can ask, "What's the weather like in Moscow?" and after a minute, you can specify, "What's the weather like in St. Petersburg?" and the assistant will understand that it's about the weather. To navigate effectively, use commands like "Build a route to the nearest gas station" or "Where to buy flowers?"
💡
Use the "Switch on the flashlight" or "Switch off Bluetooth" command to control the phone's functions without looking for them in the notification curtain, which is especially convenient when hands are busy.
Dictation commands are available for communication. In any text input field (WhatsApp, Telegram, Notes), click on the microphone on the keyboard or say "OK, Google, send a message..." to dictate long text. Russian language recognition accuracy in modern versions of Android is 95-98%.
