Modern smartphones Xiaomi, running shells MIUI or new HyperOS, are equipped with many intelligent functions designed to simplify interaction with the device. One such feature is activating the voice assistant during an incoming or outgoing call, which is sometimes enabled by default. This can be annoying, especially if you don’t plan to use voice commands, but just want to quickly answer a call or end a conversation.
Often, users are faced with a situation where the screen is blocked or, conversely, an extra menu is displayed asking you to “say a command,” which interferes with normal navigation. In some cases, this may be due to the “Voice Answer” function or active Google Assistant, intercepting control. It can be difficult to understand which component of the system causes the reaction due to the deep integration of services.
In this material we will take a detailed look at all the possible reasons for the appearance of voice interfaces during a call and offer step-by-step solutions for disabling them. You will learn how to manage settings Mi AI, customize the behavior of the call screen and prevent accidental activation of assistants, regaining full control over communications.
⚠️ Attention: The settings interface may vary slightly depending on the shell version (MIUI 12, 13, 14 or HyperOS) and regional firmware (Global, China, EEA). If you do not find the menu item, use the search in the settings by entering a keyword.
Why does the voice assistant turn on on Xiaomi
The main reason for unwanted voice activation is most often the “Voice Control” or “Voice Dialing” setting, which is active by default in system applications Xiaomi. The system's algorithms can interpret certain sounds or touches as a command to wake up the assistant. This happens especially often when the phone is in your pocket or is lying with the screen facing up.
Another factor is the conflict between the built-in assistant Mi AI and the system one Google Assistant. If the phone settings are set to call an assistant when you (long press) the power button or swipe from the corner of the screen, then this function may work incorrectly during a call. It is also worth considering that some models Redmi and POCO have a hardware button for calling up AI functions.
It is important to distinguish between situations: when the assistant turns on by itself during a call, and when you just want to turn off the ability to control the call with your voice. In the first case, we are talking about the intrusive behavior of the system, in the second - about the accessibility function, which helps people with disabilities, but interferes with ordinary users.
Disabling Mi AI and Xiao AI in the system settings
On devices Xiaomi the main built-in assistant is Mi AI (known in Chinese versions as Xiao AI). It is he who most often pops up on the lock screen or during a conversation, asking you to speak a command. To completely deactivate its interference in the call process, you need to go through several menu levels.
First, go to the main Settings of your smartphone. Find a section that may be called “More” or “Advanced Settings”, and then select Language and input. Key switches responsible for voice control are hidden here. If you have global firmware installed, look for the section simply Mi AI in the general list of settings.
☑️ Algorithm for disabling Mi AI
Inside the voice assistant menu you will need to find the option “Voice control” or “Voice Wake-up”. It is this feature that makes the phone respond to voice commands even when the screen is off. Disable the slider to prevent the system from listening to your commands in the background.
What is Xiao AI?
Xiao AI is the name of the Chinese version of the Mi AI voice assistant. On global firmware it is often renamed or limited in functionality, but the system processes remain the same. If you upgraded your phone from the Chinese version to the global one, the remnants of Xiao AI services may conflict with Google Assistant.
Setting up Google Assistant during a call
The second likely “culprit” is Google Assistantwhich is deeply integrated into the operating system Android. On smartphones Xiaomi it can take over control if the “Continued Conversation” function or the “Hey Google” mode is activated. During a call, this may lead to a command listening window appearing.
To configure, open the application Google on the main screen or go to Settings → Google → Settings for Google apps → Search and Assistant → Google Assistant. Here you will find the “Phone” or “Devices” tab, where you can limit the assistant’s work. Find "Ok Google recognition" and turn it off for Lock mode or all modes.
It's also worth checking your accessibility settings. In the Accessibility (Accessibility) section, make sure that voice control features for people with disabilities, such as Voice Accessare not enabled. These tools may activate automatically when you receive a call if they are not configured correctly.
- 📱 Open the Google app and tap on your profile avatar.
- ⚙️ Go to Settings → Google Assistant.
- 🔇 Select “Hey Google & Voice Match” and turn off recognition.
- 📞 In the “Phone” section, make sure that the assistant is not assigned to handle calls.
Managing the “Voice Answer” function and the call screen
The “Voice Answer” function deserves special attention, which allows you to receive a call by simply holding the phone to your ear and saying “Hello.” While this is convenient, it often triggers at inopportune times, such as when you're simply adjusting the phone to your ear without wanting to answer. Disabling this feature will solve the problem of random answers and microphone activation.
To find this setting, open the application Phone (dialer). Click on the three dots in the corner of the screen or the menu button, then select Settings. In the list of options, find the "Incoming calls" or "Answer and end" section. There will be a “Voice answer” switch, which needs to be switched to an inactive state.
In addition, prompts or shortcut buttons to the assistant may appear on the call screen. In new versions MIUI and HyperOS the design of the call interface changes. If you see a microphone button that launches the assistant instead of muting it, it could be a theme customization. Try changing the design theme to the standard “Classic” or “Basic”.
| Function | Where to find | What it does | Recommendation |
|---|---|---|---|
| Answer voice | Phone → Settings | Answers a call by command | Disable |
| Mi AI / Xiao AI | Settings → Mi AI | Global system assistant | Restrict access |
| Google Assistant | Google application | Search and OS commands | Configure triggers |
| Gaze control | Special. capabilities | Eye movement response | Check status |
Accessibility and accessibility
Sometimes the problem lies deeper - in the accessibility section Android. These features are designed for people with visual or motor impairments, but accidentally activating them can turn your smartphone into an uncontrollable device. For example, the function Voice Access or “Voice control” can dictate its terms during a call.
Go to Settings → Advanced settings → Accessibility. Scroll down the list to the Downloaded Services or Services section. If Voice Access, TalkBack or any other voice control services are activated there, disable them. Also check the "Physical and Motor" tab for active profiles.
⚠️ Attention: Be careful when turning off accessibility services. If you use them regularly, make sure you don't disable the feature you want. Changes take effect immediately.
In the same section it is worth checking the “No-touch Control” settings. If shaking, swiping, or voice control is enabled to perform actions, this may conflict with the dialer interface. Reset accessibility settings to factory default if you can't find a specific switch.
The Accessibility section is a powerful tool that often becomes a source of interface problems if it has control services enabled that you don't need.
Reset the Phone app settings and clear the cache
If software settings did not help and the voice assistant continues to pop up, perhaps there was a software failure in the application. Accumulated cache or damaged temporary files can cause incorrect interface behavior, including spontaneous launch of the assistant. Phone or Contact there was a software glitch. Accumulated cache or damaged temporary files can cause incorrect interface behavior, including spontaneous launch of the assistant.
To solve the problem, go to Settings → Applications → All applications. Find the application Phone (or MIUI Dialer) in the list. Click on it and select Memory. Here you need to press the button Clear cache, and then Clear all (or “Reset settings”). This will not delete your contacts, but will return the dialer settings to their original state.
A similar procedure is recommended for the application Google i Google Play Services, since they are also involved in processing voice commands. After the reset, reboot the device so that the system reinitializes all services.
- 🗑️ Go to application management.
- 📞 Find the standard Xiaomi dialer.
- 🧹 Completely clear data and cache.
- 🔄 Reboot your smartphone to apply the changes.
Frequently asked questions and problems (FAQ)
Why did the voice assistant turn on again after updating MIUI?
When updating the firmware, the system may reset some user settings to default values, considering them more optimal for the new version software. After each major update (for example, from MIUI 13 to 14 or to HyperOS), it is recommended to re-check the “Language and input” and “Accessibility” sections.
Is it possible to completely remove Mi AI from the phone?
Complete removal of the Mi AI system application without root access is impossible, since it is built into the system. However, it can be frozen or disabled via ADB commands if you are an advanced user. For most cases, it is enough to simply turn off all permissions and activation in the settings.
The voice assistant is only enabled when headphones are connected, why?
This may be due to the settings of the Bluetooth headset or the “Automatic answer” function in the Phone application. Check to see if the button on the headphones is assigned to calling an assistant, and disable automatic answering in the dialer settings.
How to disable voice notification of the caller's name?
This feature is called “Say caller's name.” It is in the application Phone → Settings → Incoming calls. There you can also disable other sound notifications that may be confused with the operation of the voice assistant.
