Modern Xiaomi and Redmi smartphones offer a wide range of features for user convenience, among which voice typing stands out. This technology allows you to dictate messages, notes and search queries, freeing your hands. However, not everyone likes the random activation of the microphone or constant prompts from the system that can distract from the main work.
Often, device owners are faced with a situation where the keyboard spontaneously switches to dictation mode, or the microphone button takes up too much space on the screen. In some cases, this may be due to the peculiarities of the Google Assistant or the system settings of the MIUI and HyperOS shell. Understanding how to manage these processes is necessary to personalize the interface to your needs.
In this article, we will discuss in detail all the available ways to limit or completely disable voice input functions. We will look at the settings of the standard keyboard, Android system parameters and specific features that can affect the activation of the microphone.
Difference Between Voice Input and Google Assistant
Before you start setting up, it's important to clearly understand the difference between two major technologies that are often confused: Voice input is a feature built directly into the keyboard that converts your speech into text in an active text field, which runs locally in the input application and depends on the layout you choose.
At the same time, Google Assistant is a global assistant that can be activated by voice command even when the screen is off or in any other application. The assistant is able to perform complex actions such as setting an alarm clock, launching applications or searching for information on the Internet, not limited to simple typing.
Disabling one of these features doesn't affect the other unless it's linked to system permissions, for example, denying access to the keyboard microphone will stop dictating text, but it won't stop the Assistant from hearing the "OK, Google" command if it's set up for a separate activation, so it's important to determine which component is causing you discomfort.
⚠️ Warning: A complete shutdown of Google system services could disrupt not only voice input, but other features that depend on Google Play services, such as screen search or smart home.
For users who value privacy, delineating these concepts is key: You can keep the Assistant active to manage the smart home, but you can completely remove the ability to dictate text in messengers, and this approach allows you to maintain functionality by removing unnecessary controls.
Turning off the microphone in the Gboard keyboard
Most Xiaomi smartphones have Google’s Gboard keyboard installed by default, which is where the voice input source is most often found, and to remove the microphone button from the toolbar, you need to go to the settings of the keyboard application itself, not the general system.
Go to your smartphone's Settings menu, then look for the Settings section and select Language and Enter. In the keyboard list, click on Gboard. Next, select Voice Input. Here you'll see a switch that allows you to completely deactivate this feature. Once you turn off the microphone icon, it will disappear from the top of the keyboard.
- 🎙️ Open Gboard settings through the system language menu.
- 🔇 Find the "Voice input" section and transfer the switch to the "Off" position".
- ✅ Check the result in any text field – the button should disappear.
If the standard path through system settings seems difficult to you, you can act faster. Just call the keyboard in any application, click on the gear icon on the top panel, or hold the comma (depending on the version) to get into the menu. From there, the path will look like Settings → Voice input.
☑️ Checking Gboard settings
It’s worth noting that some versions of MIUI firmware may have a little hidden settings. If you haven’t found the switch, try clearing the Gboard app data.This will bring the keyboard back to factory settings, where the feature can be disabled by default or easier to find when you first set it up.
Setting up and limiting Google Assistant
If your problem isn't with the button on the keyboard, but with the phone constantly listening to the activation command, set up Google Assistant, a feature that can consume battery power and cause anxiety about listening to conversations, and that requires access to the settings of the Google app itself to manage it.
Open the Google app on your smartphone, click on your profile avatar in the top right corner, and select Settings. Next, go to Google Assistant. Here we're interested in Hey Google and Voice Match. This is where the switch for voice activation is located. By disabling it, you'll stop the phone from responding to voice commands when the screen is off or locked.
| Setup parameter | Where to find out. | Recommended action |
|---|---|---|
| Hey Google | Assistant settings | Turn off to save battery |
| Voice recognition | Voice Match | Remove the voice sample |
| Access from locked screen | Security and confidentiality | Prohibit access |
You can also remove a sample of your voice in this section, which will make it impossible for the assistant to respond in a personalized way, which will further enhance privacy, but remember that the assistant will not be able to distinguish between the commands that are intended for you if you share the device with other people.
Why does the assistant turn on himself?
For those who want to leave the assistant but remove it from the lock screen, there is a separate switch in the Lock with the screen off section, which will allow you to use voice search only when the phone is unlocked, which is a good trade-off between convenience and security.
Managing Application Permissions in MIUI and HyperOS
The MIUI shells and the new HyperOS have extended control over application permissions, so you can completely deny the keyboard or any other application access to the microphone at the system level, a radical but effective method if standard settings don't work.
Go to Settings → Privacy Protection → Permissions Manager. Go to Gboard or Google. Click on Microphone and select Prohibit. After that, any application that tries to use voice input through that keyboard will be denied access, and the function will simply stop working.
- 🔒 Go to “Privacy Protection” in the main settings menu.
- 📱 Select "Permissions Manager" and find the desired application.
- 🚫 Implement a ban on the use of microphones.
It’s important to understand the consequences of this action. If you deny access to the microphone for Gboard, you will not be able to use dictation in any application, including WhatsApp, Telegram or notes. In addition, some input enhancements based on audio analysis will also become unavailable.
⚠️ Note: When you update your system or reinstall Google Play Services updates, permission settings may reset to default values, so it’s worth checking this section periodically.
This method is especially useful for users who want to be absolutely certain that no app can secretly activate a sound recording.The Android system is sure to notify you every time an app tries to access the microphone if you turn on the appropriate indicator in the notification curtain.
Third-party keyboards as an alternative
If Xiaomi’s built-in tools and Google’s settings don’t work, or the interface seems too overloaded, installing a third-party keyboard is a great solution. Many alternative text-entry apps have more flexible settings and allow you to completely remove unnecessary interface elements, including the voice input button.
Popular keyboards like Yandex Keyboard, SwiftKey, or OpenBoard offer their own implementations of voice input or make it easy to disable in one click. For example, in Yandex Keyboard settings, you can not only turn off the microphone, but also choose whether to use Google's engine or your own recognizer.
To install a new keyboard, download the app from Google Play Market. Once installed, the system will prompt you to activate the new input method. Go to Settings → Additional Settings → Language and Input → Keyboard Management and turn on the switch opposite the new application. Then select it as the default input method.
💡
Use open source keyboards like OpenBoard if you're concerned about data collection.They often don't have built-in voice input at all, ensuring there's no accidental activation.
Using a third-party solution can also have a positive impact on device performance: Third-party keyboards often weigh less and consume less RAM than Google’s heavy services integrated into Gboard. This is especially true for the budget Redmi and POCO models with limited RAM.
Cleaning data and resetting input settings
In situations where voice input is behaving incorrectly, pops up constantly or is not disabled by standard methods, cleaning the application data can help. This action will return the settings of the keyboard and Google services to factory state by removing accumulated configuration errors.
To do this, open Settings, go to the Applications → All Apps. Go to the Gboard list (or Google if the problem is in Assistant). Click on Clean and select Clear Everything. Then, the next time you run the keyboard, you will be prompted to reset the original setting, where you can immediately refuse to activate voice functions.
The procedure also removes the usage history and personalized vocabulary learned by the keyboard, and while this is a temporary inconvenience, it often resolves software bugs when the system forgets your previous microphone bans.
⚠️ Note: Before clearing the data, make sure that your important notes or passwords stored in the keyboard dictionary are not lost, as the process is (irreversible) for local data.
If that didn't work, you can try removing the Gboard updates. To do this, in the same app information menu, click on the three dots in the upper right corner and select Remove Updates. The phone will roll back to the factory version of the keyboard that could have been installed when the device was released. After that, you can update the app again through the Play Market, but with clean settings.
💡
Data cleanup is the "heavy artillery" in setting up a smartphone, and it's effective when simple switches stop working because of software failures.
