Revocation of the robot vacuum cleaner Xiaomi: how to change voice to Russian, English or custom

Xiaomi’s robot vacuum cleaners have long since ceased to be just appliances — they have become full-fledged assistants with their own “character.” One way to personalize the device is to change the standard voice for a more pleasant, funny or even voiceover from your favorite character. However, the official documentation of Mi Home does not mention this possibility, and careless actions can lead to a firmware failure or loss of warranty.

In this article, we will discuss all the working voiceovers for Xiaomi Mi Robot, Dreame, Viomi and others based on the Mi Home/MiJia platform. From simple language change through the application to manually embed custom voice packets with ADB and modified firmware, special attention will be paid to the risks of locking the device using informal methods - and how to avoid them.

Why Standard Voice Can Be Irritating (and When to Change It)

Xiaomi manufacturers use synthesized voices with minimal emotional coloration, which for some users is a plus — neutral timbre is not distracting.

• 🔊 Monotony: The standard Mi Robot voice sounds robotic (literally), which is tiring when used frequently.
• 🌍 Incorrect translation: in Russian firmware errors such as “cleaning is completed” instead of “cleaning is completed” are encountered».
• 🎭 No personalization: no choice of gender, timbre or style (e.g. child voice for families with children).
• 🚫 Technical bugs: on some models (Dreame) D9, Viomi V3) voice interrupts or sounds with a stutter.

According to a survey of Xiaomi robot vacuum cleaner owners (2023), 38 percent of respondents would like to change the voice of a device but are afraid to break it. In fact, safe voiceover methods exist - and we'll consider them.

What can be done without risking the guarantee

If your model supports multilingualism, the first step is to check the settings in the Mi Home app, which is 100% secure and requires no technical skills.

How to change your voice language through Mi Home:

1. Open the app and select your robot vacuum cleaner.
2. Go to Settings → General → Voice Language.
3. Choose from the available options (usually there are English, Chinese, Russian, Spanish).
4. Confirm the change and wait for the device to restart (it will take 1-2 minutes).

⚠️ Note: On some models (Xiaomi Mi Robot Vacuum-Mop 2 Lite, Dreame) Z10 Pro) Change of voice resets room maps and custom cleaning settings. Save backup via Settings → Other functions → Backup before changing.

If the list does not contain the language you want, try updating the firmware:

• 📱 In Mi Home: Device profile → Update of the PO.
• 🖥️ Through the web interface: connect the vacuum cleaner to Mi Home on PC and check for updates.

💡

If after updating the firmware voice began to sound quieter or with interference, try resetting the sound settings: go to Settings → Sound and alerts → Reset to factory.

Informal methods: custom voices and firmware

For those who don't have the standard options, there are alternative voiceovers that require more effort and risk, but they offer access to:

• 🎤 Celebrity voices (for example, voice acting from Alice from Yandex or voice acting).
• 🤖 Personalized phrases (you can record your child's voice or voice).
• 🎮 Thematic packages (voice of Darth Vader, Terminator or Jarvis from Iron Man).

All informal methods fall into three categories:

Let’s look at each method in more detail.

Method 1: Replace audio files via ADB (for power users)

This method is suitable for models based on Android or with open access to the file system.

• 💻 Computer with Windows/Linux and established ADB.
• 🔌 USB-Type-C Cable (to connect vacuum cleaner to PC).
• 📁 Ready-made package of voice files in.ogg format (you can download on the forums) 4PDA or XDA-Developers).

Step-by-step:

1. Turn on the developer mode on the vacuum cleaner: Click 5 times on the "Software version" in the device settings.
2. Activate Debugging by USB in the developer menu.
3. Connect the vacuum cleaner to the PC and check the connection with the command: adb devices (the device name should be displayed).
4. Copy sound files into a folder /system/media/audio/tts/: adb push custom_voice/ /system/media/audio/tts/
5. Reboot the device: adb reboot

Download ADB Tools from the official website |Install drivers for your vacuum cleaner model |Create a backup of the original audio files |Check the compatibility of the voice packet with your firmware-->

⚠️ Note: Some models (Roborock) S7) They block the entry to the system folders, and in this case, you'll need to unlock the bootloader, which cancels the warranty, and the alternative is to use Magisk to get root rights without unlocking it.

Method 2: Firmware custom software (Valetudo, DustBuilder)

For advanced users willing to sacrifice official firmware, there are alternative firmware with advanced features.

• 🛠️ Valetudo – open firmware with support for custom voices and integration with Home Assistant.
• 🤖 DustBuilder - modified software for Xiaomi/Roborock high-pitched.

Firmware process:

1. Download the firmware from the official repository (Valetudo on GitHub).
2. Unpack the archive and connect the vacuum cleaner to the PC in fastboot mode (hold the power + Home button when turned on).
3. Run the firmware script: flash.sh (for Linux/MacOS>) or flash.bat (for Windows).

⚠️ Attention: Valetudo's firmware disables cloud sync with Mi Home, all room maps and cleaning settings will be reset, and there may be problems with updates - they will have to be installed manually.

💡

Custom firmware strips you of warranties, but gives you access to advanced features including voice replacement, smart home integration, and removing manufacturer restrictions.

Method 3: Cloud Services (Home Assistant, Node-RED)

If you use Home Assistant or other smart home systems, you can redirect voice alerts through the cloud, which doesn't require any interference with the vacuum cleaner's firmware, but depends on the stability of the Internet connection.

How to set up:

1. Install the Xiaomi Miio component in the Home Assistant.
2. Add the vacuum cleaner as a device through a token (you can get it in Mi Home via Settings → General → API Token).
3. Create an automation that will play custom audio files at events (such as the beginning/end of a cleaning).

Example of code for configuration.yaml:

media_player:


- platform: command_line




command: "mpg123 /config/sounds/clean_start.mp3"





automation:




- alias: "Custom voice for vacuum start"




trigger:




platform: state




entity_id: vacuum.xiaomi_vacuum




to: "cleaning"




action:




service: media_player.play_media




target:




entity_id: media_player.custom_voice




data:




media_content_id: "/config/sounds/clean_start.mp3"




media_content_type: "music"

Pros of the method:

• ✅ No risk to the guarantee.
• ✅ Any sound files can be used (.mp3,.wav).
• ✅ Easily integrates with other smart home devices.

Cons:

• ❌ Sound delay (1-3 seconds).
• ❌ You need a permanent server (Home Assistant).

Where to download voices for the robot vacuum cleaner Xiaomi

Sources of high-quality voice packets:

⚠️ Attention: Only download files from trusted sources. In 2023, there were cases of malicious scripts spreading under the guise of voice packets that blocked the vacuum cleaner with a demand for ransom.

If you want to create your own voice pack, use the following programs:

• 🎙️ Audacity – for recording and editing sound.
• 🔊 FFmpeg – for conversion to.ogg format (command: ffmpeg) -i input.mp3 -c:a libvorbis -q:a 4 output.ogg).

Frequent Mistakes and How to Avoid Them

Even if you follow the instructions, you might run into problems, and let's look at the typical mistakes and solutions.

• 🔇 Voice Disappears After File Replacement: Check File Access Rights (chmod) 644 Make sure that the file names are the same as the original ones (e.g.,.ogg, start_cleaning.ogg).
• 🔄 Vacuum fixated on reboot: Reverse to factory firmware via Mi Home (Settings) → Update of the PO → If it doesn't work, use fastboot to flash it back.
• 🗣️ Castom voice sounds robotic or jammed: Check the bitrate of files (64-128 kbps recommended). Use Mono format, not Stereo.

If after re-voicing the vacuum cleaner stopped responding to commands, try:

1. Reset the settings to factory (Settings → Reset).
2. Reconnect the device to Mi Home (remove and add again).
3. Update the firmware through OTA (if available).
