Voice Match is one of the key features of Google’s ecosystem, integrated into the MIUI and HyperOS shell on Xiaomi smartphones.It allows the device to recognize a specific user’s voice by providing personalized access to information, calendar and smart home without the need to unlock the screen.However, despite the convenience, many owners face the need to deactivate this option due to false positives, privacy issues, or simply to save battery power, which is spent on constantly listening to the microphone.
Disabling Voice Match on Xiaomi devices can be required in a variety of situations: when selling a gadget, transferring it to another family member, or if the assistant begins to react to extraneous sounds and voices. The deactivation process is not complex, but requires an understanding of the structure of Google settings, which may vary depending on the version of the Android operating system and the version of the shell. In this article, we will discuss in detail all the steps necessary to completely disable the feature, and also consider the related settings that affect the voice assistant.
It is important to understand that the complete removal of the voice profile is different from the temporary disabling of the recognition function. Resetting the voice model requires a re-learning procedure to activate the function in the future, so before making changes it is worth weighing all the pros and cons. Below we will provide comprehensive information on how to manage these parameters effectively and securely for your data.
What is Voice Match and Why Turn It Off
Voice Match is a biometric identification technology that uses the unique characteristics of your voice to verify your identity. On Xiaomi smartphones, this feature is closely integrated with Google Assistant, allowing you to execute commands like "OK, Google" even when the screen is off. The system analyzes the timbre, intonation and pronunciation, creating a digital cast that is stored locally or in the Google account cloud.
There are several reasons why users choose to disable this feature: First, privacy issues: some users do not want their device to constantly "listen" to the environment in anticipation of a trigger phrase; second, it is annoying false positives when a TV or a conversation bystander activates the assistant; third, constant background listening can consume a noticeable amount of energy, which is critical for older batteries.
It’s also worth noting that on Redmi and Poco devices with aggressive battery optimization, the feature can work unstablely, spontaneously turning off or, conversely, without turning off. If you notice that the smartphone responds to strangers’ commands or makes activation sounds at the wrong time, disabling Voice Match will be the best solution to regain control of the device.
Preparing the smartphone before changing the settings
Before you start changing system settings, make sure your device is ready to make changes. While disabling Voice Match does not require superuser rights or data resets, the stability of the system depends on the current state of the software. Make sure your Xiaomi is connected to the Internet, as some changes to Google profile can be synchronized in real time.
It is recommended to check the version of the Google and Google Assistant app in the Play Market Store.Outdated versions of the applications may have a modified settings interface or contain errors that prevent the function from being disabled correctly.Updating to the latest version ensures that you see the current menu items and security algorithms.
If you plan to completely remove your voice profile, rather than just disable the feature, you should prepare alternative unlock methods in advance. For example, if Voice Match was used as an additional authorization method, make sure you have a reliable one. PIN-A code, pattern lock, or a fingerprint scanner is configured to prevent you from losing access to some personalized features after you turn off voice control.
☑️ Preparation for setup
The main way to disable through Google settings
The most reliable and standard method of deactivating Voice Match on any Xiaomi device is to use the settings menu of the Google app itself.This path is universal for most Android versions and MIUI shells. To start, open the Google app on your smartphone - this is an icon with the letter "G" on the home screen or in the app menu.
Once you start the app, click on your profile avatar in the top right corner of the screen. In the menu that opens, select Settings. Next, search for the Google Assistant section and go to Hey Google and Voice Match, and that's where all the key switches that are responsible for activating voice control are concentrated.
Inside the menu, you'll see the Hey Google switch, and turning off this slider completely deactivates the voice-activated assistant, and if you want to leave the activation option but remove the voice-based anchor, find Voice Match and turn it off, and the system can request confirmation of action, warning you that personalization will be lost.
What happens when you turn off Hey Google?
Removal of voice model and data reset
Simply turning off the switch may not be enough if you want to completely erase your voice recording from the device’s memory, which is especially true when selling your phone or transferring it to another user. To remove the saved voice model, you need to go back to the Voice Match menu where you previously disabled the feature.
At the bottom of the screen or in the optional settings menu (often indicated by three dots), find the option Delete Voice Model. The system will warn you that after this action, Google Assistant will no longer be able to recognize your voice.
Once you do this, the database with your voice cast will be cleaned, so if the next user wants to use Voice Match, they will have to relearn the process by saying "OK, Google" several times, ensuring that your biometrics are not left on the device.
It is important to note that deleting your voice model does not affect your voice search history stored in your Google account. To delete your activity history, you must go to the My Activity section of your Google account settings and clear your voice input history separately.
💡
Before selling your phone, not only delete the voice model, but also log out of your Google account in your system settings so that the data doesn’t sync on the buyer’s new device.
Set up personalization and access to data
Voice Match is closely related to the level of personalization that Google provides to the user. Even after voice recognition is disabled, some access settings may remain active.
Here, you can control your assistant’s access to your personal information, such as contacts, location, media files, and search results. Disabling Contacts or Location will limit the assistant’s ability to answer questions like “Where is my home?” or “Call Mom” even if Voice Match is turned off.
Also worth paying attention to is the Customization Block settings. There is a separate switch on some versions of MIUI that prevents you from showing personalized results on a locked screen, an important layer of security that prevents data leakage if someone else tries to use the voice assistant on your locked phone.
| Setup parameter | Impact on work | Recommendation |
|---|---|---|
| Hey Google | Activates listening to the trigger phrase | Disconnect to save battery |
| Voice Match | Allows voice access on a locked screen | Turn off when transferring the phone |
| Personalization | Provides access to contacts and history | Restrict in public places |
| Voice commands | Allows hands-free control | Leave it on for navigation |
Solution and additional settings
Sometimes users are faced with a situation where Voice Match does not turn off or continues to work incorrectly even after making changes to the settings, this may be due to the cache of the Google application or conflicts in the operation of the MIUI shell.
To do this, go to Settings → Apps → All apps, search the Google app list, select Memory and click Clear Cache. Don't confuse this with data cleanup, as it will reset all the application settings to factory. After cleaning the cache, restart your smartphone and check the function.
Another common problem is the conflict with the feature “Improving speech recognition.” In the settings of Google, in the Voice section, the feature can be activated to improve recognition, which sends records to Google servers. Disabling this option can increase privacy, but in theory it can affect the accuracy of Voice Match if you decide to turn it on again.
💡
If standard methods don’t work, try temporarily shutting down the internet, turning off Voice Match, and then turning the network back on – this will update the status of the feature on the server.
