Many smart homeowners face a situation where a robot vacuum cleaner from China or Europe speaks a foreign language. Standard English or Chinese voice can be annoying, especially if the device loudly announces about completing a cleaning or getting stuck. Fortunately, Xiaomi’s ecosystem allows you to solve this problem by software methods without opening the device’s body.
The process of changing the voice packet is directly related to the region chosen in the Mi Home app. It is the server binding that dictates which set of audio recordings will be downloaded to the device when initially set up, but there are ways to bypass these restrictions and set the desired language, whether it is Russian, Ukrainian or even customized voices of enthusiasts.
In this article, we will cover all the current methods, from simple change of region in the application to more complex manipulations using ADB (Android Debug Bridge), you will learn how to safely reflash your janitor’s audio system and avoid turning your gadget into a “brick.”
Why does the robot speak a foreign language?
The main reason for the language barrier lies in logistics and regional sales: Global versions of devices often have multilingual support, but only activate the desired package when initially linked to a server of a particular region. If you bought a device designed for the domestic market of China, by default it will use Chinese or English.
The MIOT (Mi IoT) shell architecture tightly links configuration files, including audio libraries, to a user's account, to standardize service and simplify country-specific technical support. Trying to simply change the language in the application interface often doesn't affect the system sound files of the vacuum cleaner itself.
⚠️ Warning: Forced region change in the Mi Home app without first untieing the device can result in loss of cleaning history and maps of the premises. Always back up the maps if this feature is available in your version of the software.
There is also the notion of firmware localization. In some models, such as the Xiaomi Vacuum Mop 2 Pro or Roborock S5 Max, the voice engine is part of the firmware, which means that a full voice change may require updating or flashing the entire device, not just replacing the audio file.
Preparation for the change of voice packet
Before you start taking action, you need to prepare a software environment: you need a smartphone with an Android or iOS operating system, a stable Internet connection and an account in the Xiaomi Cloud system. It is desirable that the version of the Mi Home application is the last available in the official store.
You also need to check the battery level of the robot. The process of updating the configuration or firmware is energy intensive. If the device sits down at a critical time when it writes new data to memory, this can lead to a software failure. Put the vacuum cleaner on the base and make sure that the indicator is green or flashing green.
☑️ Checklist before firmware
An important step is to determine the exact model of your device. Modifications with the index Global and CN (China) can have different memory sections. For accurate identification, look at the sticker on the bottom cover or in the application in the Settings → General information section.

The method of changing the region in the application Mi Home
The easiest and safest way to change voice is to manipulate the region in the app, which works for 90 percent of current models, including the Roborock, Dreame, and Viomi series, and the method is to re-register the device to the servers of the desired region.
To begin, you need to completely remove the device from the current list in the app. Click on the vacuum cleaner icon, select three dots in the upper right corner, and click Remove the device. After that, reset the Wi-Fi module on the robot itself. This is usually done by long-term pressing of the combination of buttons (often it is the power button and the home return button at the same time) before the beep.
Next, change the region in the Mi Home profile settings. Go to Profile tab, then Settings and select Region. Set the country whose language you want (for example, Russia for Russian voice). After changing the region, the application may require you to re-enter the account.
| Server region | Available languages | Features |
|---|---|---|
| Russia | Russian, English | Full localization, stable operation |
| Germany | German, English | European servers, high speed |
| China | Chinese, English | Maximum functionality, but the Chinese interface |
| Singapore | English | It is often used as an alternative to global versions. |
After changing the region, add the device again, following the instructions on the screen. When you initial synchronize, the vacuum cleaner will download the relevant set of voice commands for the selected region. If the voice does not change immediately, try rebooting the robot by holding the power button for 5-10 seconds.
💡
Changing the region to Mi Home is a regular method that is not in breach of warranty and is secure for the device. It works at the server authorization level.
Use of modified voice packets
For advanced users who don't like standard voices, custom audio files can be installed, enthusiasts can create packages with famous voices or just a nicer timbre, a process that requires the use of a computer and an ADB utility.
First you have to enable Wi-Fi debugging on the robot itself, and on some models, it's a hidden feature. 5-7 once to a specific area in the application (often the logo of the software version) or use special tokenization scripts. IP-The device address will be required to connect.
adb connect 192.168.1.XX:PORT
adb shell
cd /mnt/UDisk/voices
ls -laOnce connected through the console, you access the file system, and you need to find a directory that contains audio files (usually.mp3 or.ogg formats), and if you replace the standard files with the same name, you change the voice of the device, and you need to follow the naming structure, otherwise the system will not find the file you want.
⚠️ Note: Replace system files through ADB If you're not sure what you're doing, just use the region change method. If you don't know what you're doing, you can rename files incorrectly.
There are also ready-made configuration utilities, such as miio or valetudo web interfaces (for Linux models on board), that allow you to download sounds through the GUI without manually typing commands, a more convenient but technically more complex way that requires you to install additional software on your PC.
Comparison of voice firmware methods
The choice of method depends on your technical background and the model of the device, and here is a comparison of the basic approaches so that you can choose the best one for yourself.
The application-based method is the preferred method for most users. It requires no special knowledge and is reversible at any time. The ADB method gives complete control, but takes time to learn. Castom firmware (complete OS flashing) is an extreme measure that is rarely required just for the sake of changing voice.
| Method | Difficulty | Risk of failure | Preservation of the guarantee |
|---|---|---|---|
| Change of region | Low. | Minimum | Yes. |
| ADB (file replacement) | Tall. | Medium. | No (formally) |
| Complete flashing. | Extremely extreme. | High-pitched | No. |
It’s worth noting that some new models with Android on board allow third-party apps that can control voice output, but these are still a minority and they belong to the premium segment.
💡
Tip: Before replacing any files with ADB, make a full copy of them to your computer, which will allow you to restore the original voice in case of failure.
Possible problems and solutions
As users change their language, they may encounter a number of challenges, and it often happens that after a region change, the robot continues to speak the same language, because of the caching of the data in the application, and the solution is simple: completely uninstall the Mi Home app, reinstall it, and log in to the new region.
Another common problem is a connection error when trying to link to a new server. Make sure your router distributes a 2.4GHz network. Many Xiaomi robot vacuum cleaners do not support 5GHz, which causes errors when initially configuring and updating packages.
If the robot is intermittent or makes strange sounds, it may have damaged the voice file when it boots. Try resetting the device completely to factory settings. 10-15 You'll be able to reset the system for a second until you hear the reset.
⚠️ Attention: If after all the manipulations, the robot stopped responding to commands and only the error indicator burns, the partition table may be damaged. UART, necessitate disassembly.
If the memory chip does not physically write Russian (for example, in the cheapest models for the domestic market of China), it will not be possible to add it software without completely replacing firmware with a global version, which is not always possible.
