Owners of smart appliances often face the monotony of standard voice notifications that their robot vacuum cleaner issues. The standard phrase "Start cleaning" or "Stuck, help" sounds dry and quickly squanders, depriving the gadget of individuality. Fortunately, the Xiaomi Mi Home ecosystem allows users to make changes to the audio of the device, making the cleaning process more entertaining.
Many people don't realize that the voice packet is not a static file, but a replaceable firmware component. Depending on your device model, whether it's a Roborock S50, Xiaomi Vacuum Mop 2 or newer versions, the ways you change your voice may be different. Some methods require deep intervention, others are available through standard application settings.
Before you start experimenting, it's important to understand the architecture of how sound works in these devices, because audio files are stored in a special partition of memory and downloaded at the request of the system process, and by changing them, you're actually swapping the original content for your own, which opens up a lot of possibilities for creativity, but requires caution.
Compatibility check and device preparation
The first step should always be to identify the exact model of your assistant. Not all devices in the Xiaomi line support full-fledged change of voice packets at the user level without root rights. Usually this option is available to models running Android or specialized OS with open source. API.
You need to make sure that the device firmware is updated to the latest version. Older versions of the software may contain bugs that do not correctly recognize changed audio files or block access to system folders. You can check the version in the Settings → Device → Software version.
⚠️ Warning: Before any manipulation of system files, make sure that the robot battery is charged at least 60%. interruption of the data writing process due to battery discharge can lead to software failure (brick).
You also need to have a computer or smartphone with enough free memory, you need MP3 or WAV files to replace standard notifications, and the sound quality should be high, preferably at a sample rate of 44.1 kHz, so that the robot does not wheez.
The official way to change language and voice
The easiest and safest way to diversify a robot's speech is to use built-in language packs. Mi Home or Roborock often hides alternative voices that can be activated without risking damage to the device. Go to the device menu and find Voice Pack or Voice Pack.
Here you can find not only different languages, but also voices of celebrities or characters, if they were released by the manufacturer for your region. For example, for Chinese versions of devices, packages with voices of popular actors are available, which enthusiasts sometimes adapt for global versions.
- 🎙️ Open the app and select your vacuum cleaner on the home screen.
- ⚙️ Go to Settings (three dots in the corner) and find the Voice section».
- 📥 Select the available package and click “Download” or “Install».
- 🔊 Wait for the installation to be completed, the robot will confirm the success with a new phrase.
If you don't like the standard set, you can try changing the region of the device. Sometimes switching the region in the application settings (for example, from Russia to China or the United States) opens up access to exclusive voice libraries.
💡
Before changing the region, take a screenshot of the current cleaning schedule settings, as they may reset when switching servers.
Use of third-party voice packets
For advanced users who are not afraid of technical details, custom voice packs can be installed. Enthusiasts from around the world create communities where they share modified files, such packages can contain phrases from movies, memes or simply more pleasant timbres.
The installation process usually involves connecting to the robot via protocol. SSH or the use of special utilities for Windows/Mac. You'll need to know. IP-You can do this through the router or in the application itself in the Wi-Fi information section.
Once you access the file system (often requiring unblocking through miio or special tokens), you replace the files in the /mnt/UDISK/voice directory. File names must strictly match the original, otherwise the robot will not understand what audio to play in a particular situation.
| File. | Original phrase | What can be replaced |
|---|---|---|
| charge_start.mp3 | Back to base. | "I'm going on vacation, don't wake up!" |
| stuck.mp3 | I'm stuck. | "SOS! Need help!" |
| clean_start.mp3 | Starting cleaning. | "Time to destroy the dust!" |
| clean_complete.mp3 | Cleaning complete. | "Mission accomplished, boss." |
Malicious code can theoretically get into a device, although in practice this is rare. Always check the files with antivirus and read feedback from other users on forums before installing.
☑️ Checking before installing custom voice
Technical requirements for audio files
For a robot vacuum cleaner to correctly reproduce your “fun” phrase, the audio file must meet strict technical requirements. The built-in speakers in these devices are not of high quality, so complex musical compositions can sound like porridge.
The optimal format is MP3 with a bitrate of 64 or 128 kbit / s. WAV format is possible, but such files take up more space, and the robot memory is often limited. The duration of one phase should not exceed 3-5 seconds, otherwise the system timer may interrupt the playback.
When recording your own voice, use a voice recorder with a good microphone. Speak clearly, a little louder than usual, and with an expression. Emotional coloring is important, because the robot's monophone speaker cuts many frequencies, making the voice flat.
⚠️ Note: Do not use files with embedded files DRM-The robot can't decode them, and at best you'll hear silence, and at worst, a system error.
You can use free audio editors like Audacity to edit files, where you can normalize the volume so that all phrases sound the same, and cut off the unnecessary pauses at the beginning and end of the track.

Creating your own voice package from scratch
If you don't like the solutions you're making, you can create a unique voice for your smart home, a creative process that allows you to incorporate personalized humor into your life, and you can record the voice of a friend, child, or even a pet (if they could talk).
Make a list of all the events that the robot responds to, and it's not just the start and finish of the cleaning, it's also the errors: "Pick up the sensor," "Pick up the main brush," "The tank is full," and you have to prepare a separate file with the right name for each event.
- 📝 Make a match table: event – file name – phrase text.
- 🎤 Record audio in a quiet room without echoes or extraneous noises.
- ✂️ Process files in the editor, bringing them to a single standard.
- 📂 Rename files according to your model’s system requirements.
Once you've prepared the file packet, put them in one folder. Before you upload them to the robot, double-check the names again. One error in the character (e.g., a single error in the character, clean_start.mp3 instead clean_start.mp3) This will cause the robot to ignore the file and keep silent at the right time.
There are special converter utilities that automatically rename files and pack them into the desired format for specific Xiaomi models.
💡
Record quality and filenames are two of the main factors of success: a technically competent file with a stupid name will not work.
Frequent problems and ways to solve them
You can have a lot of trouble modifying your voice, and it can ignore new files, play them with distortions, or stop making sounds altogether, and it's often the format or bitrate of the audio that's incompatible.
If the robot is silent, check if the app has "No Sound" or "Do Not Disturb" mode on, and sometimes when the firmware updates, the settings are reset, or the new voice packet requires re-activation through the menu.
If the robot starts to make errors or behave strangely after installing a custom voice, you need to reset the settings, this will return the original files and restore the stable operation of the device.
⚠️ Warning: If the robot starts buzzing or makes strange mechanical noises after replacing the files, turn it off immediately, which may indicate a conflict of software interruptions, although this is extremely rare.
Remember that software modifications can affect warranty, and if the device is in warranty service, it is better to limit yourself to official language change methods through the app.
