Xiaomi’s current smartphones have a powerful hardware, but their true potential is only revealed when the right software setup is in place. One key element of the Android ecosystem is the voice assistant, which lets you control your device without touching the screen. Users often find that after buying or upgrading the system, voice commands stop working or don’t activate at all.
In this article, we’ll take a closer look at how to turn on Google’s voice assistant on Xiaomi, and fix common bugs associated with the MIUI or HyperOS shell. You’ll learn how to customize the “OK, Google” phrase recognition, adjust your microphone settings, and optimize background processes for instant response.
Whether you own a budget Redmi or a flagship Xiaomi, the basic activation principles remain similar, although the paths in the menu may differ slightly.
Check basic settings and availability of Google services
Before you start fine-tuning, you need to make sure that your device has all the necessary components installed. On global versions of Xiaomi firmware, Google services are already built in, but on Chinese versions (CN), they will have to be installed manually through Google Play Market or third-party installers. Without the basic package Google Services Framework, you can not activate the assistant.
Go to Settings and find the App. Google must be on the installed list. If it's not, download the official app from GetApps or Play Market. Also make sure you have the latest version of the Google app itself installed, as older versions may not support new voice recognition features.
It's important to check if the system constraints are turned off for the service. The MIUI shell is known for its aggressive energy savings that can block background processes. Go to Settings → Battery and Performance and find the Google app on the list. Set Unlimited mode so that the system doesn't "kill" the listening process.
- 📱 Make sure that your Google account is added to your system and sync is enabled.
- 🔍 Check for updates to the Google app in the Play Market Store.
- 🔋 Set energy saving mode for Google services to the status of “No restrictions».
- 🌐 Make sure your country and language are selected in the Google App settings.
⚠️ Note: If you use custom firmware or a heavily modified build MIUI, Standard activation methods may not work due to lack of system security certificates.
Activation through the Google app
The main method of enabling voice assistant is directly inside the Google app. Open the app, tap your profile avatar in the top right corner, and select Settings. Next, go to Google Assistant, and that's where all the key switches that are responsible for functionality are concentrated.
Find All Assistant Settings and scroll to Hey Google and Voice Match. Turn on the "Hey Google" slider. The system will ask you to say a few phrases to train your voice recognition model, which is a critical step, as it improves activation accuracy in noisy environments.
If the slider is not activated or is gray, this indicates a setting conflict or lack of necessary permissions. In this case, try clearing the cache of the Google app through the Settings menu → Apps → Google → Memory → Clear the cache. After restarting the device, try again to activate.
☑️ Activation checklist
In some cases, especially on older Redmi or Poco models, additional activation may be required in the Laboratory Features section inside the Assistant settings, where you can find experimental options that sometimes help wake up a broken module.
Setting up Voice Match and Recognition of “OK Google”
Voice Match allows the phone to respond only to the voice of the owner, which increases security and reduces the number of false positives. When you first set up, the system will record several pronunciations of the activation phrase. It is recommended to perform this procedure in a quiet room, holding the phone at a normal distance, as you hold it when you talk.
If your phone doesn't recognize your voice, you can start learning again, go to Hey Google and Voice Match and select "Retrain your voice model," which is especially true if you've recently been sick or changed your speech, and Google's algorithms adapt to the timbre and intonation of a particular user.
You can also use this section to set up voice unlocking, and by activating Voice Match unlocking, you can open the screen by simply saying a command, but it's worth remembering that this method is less secure than a fingerprint scanner or Face ID, because you can record the voice.
- 🗣️ Retrain your voice in a quiet room without any noise.
- 🔒 Use voice unlock only in a safe environment.
- 🔄 Update your voice model periodically to improve recognition.
⚠️ Attention: Voice unlock may not work if the phone is down screen or in your pocket, which is a measure of protection against accidental activation.
Permissions and access to the microphone in MIUI and HyperOS
Xiaomi shells have a strict permission management system. Even if everything is set up correctly in the Google app, the system can block access to the microphone. Go to Settings → Privacy Protection → Permissions Manager → Microphone. Make sure there is a tick in front of the Google app.
Special attention should be paid to the function of “Privacy Protection” in newer versions of HyperOS. There can be included the option “Microphone off”, which globally prohibits access to sound recording. Check the status of the microphone indicator in the notification curtain: if the green dot is on, access is available, if the microphone is crossed out, access is blocked by the system.
Sometimes it helps to completely reset permissions for all applications. → Annexes → Settings (three points) → Resetting application preferences: This action will not delete your data, but will return all permissions to factory values, which often solves the problem of hidden locks.
| Parameter | Status for work | Where to find out |
|---|---|---|
| Microphone | Permitted. | Permit Controller |
| Auto-start | Included. | Applications → Auto-Run |
| Working in the background | No restrictions. | Battery → Application settings |
| Network access | Wi-Fi and Mobile Data | Permit Controller → Network |
💡
If the microphone indicator in the curtain is constantly on orange, check which app uses the sound. This can be a voice recorder or a messenger blocking access for the Assistant.
Solving problems with Russian language and accent
One of the common problems is that the input language is not properly defined or that Russian is not included in the list of supported languages for Voice Match. Go to Google Assistant settings, select Languages. Make sure the first language is "Russian (Russia)". If it is not, add it from the list of available languages.
Sometimes, the Assistant may ignore the command in Russian if the Gboard keyboard or system language settings have a different priority. Make sure that the Google App also has Russian in the Language and Input section. For Voice Match to work well, it is recommended that the phone interface language and the Assistant language match.
If you use regional settings other than your country of residence (e.g., U.S. in Russian), some features may not be available, and changing the region in your Google payment account profile or Play Market settings to Russia or Kazakhstan (depending on the availability of services) often solves the problem of the Russian-language Voice Match disappearing.
