The desire to personalize the work of smart technology often leads users to search for non-standard solutions, and replacing the standard voice with a more expressive or even “obscene” is no exception. The owner of Xiaomi may face a situation where the native voice seems too faceless, and you want to add humor or just surprise guests with an unusual reaction of the device. However, it is worth noting immediately that Xiaomi does not release official packages with profanity, since this contradicts corporate ethics and security rules.
However, enthusiasts and third-party software developers have found ways to circumvent these limitations by creating modified audio files and how to embed them into the device, and the process of installing such content requires intervention in the software part of the robot, which always carries certain risks. You will have to work with system files, change network settings and possibly refashion the device, so the approach should be as balanced and accurate as possible.
In this article, we will explore the technical aspects of audio file replacement, the differences between Wi-Fi-enabled models and local control, and why the concept of matte voice is most often the result of the work of the mod community. We will not call for violation of the rules, but technically describe the process of replacing system sounds with any user-generated ones, whether it is friends' recordings or downloaded audio tracks from the network.
Reality and myths about voice packets for robots
The first thing to understand before any manipulation is the sound system architecture in Xiaomi devices. Voice messages are stored in a special memory section and activated depending on the selected language location. When you change the language in the Mi Home or Xiaomi Home app, the robot downloads the corresponding set of audio files. This is the principle that the substitution is built on: the system thinks that it is playing a standard English or Chinese package, but in fact plays your downloaded file.
There is a common misconception that matte voice is some hidden feature that you just need to activate in the settings. It's not. There is no secret code or hidden menu. All the cases that are reported on the Internet are the result of manually replacing firmware files or using third-party localization servers. Users often confuse the ability to install any sound with the presence of a ready-made mat package that can be downloaded.
It is important to distinguish between open-source models and those with strict limitations: older models like Xiaomi Vacuum Mop 1 or early versions of Roborock. S5, New devices with updated protection can require complex manipulation of the device. SSH-Without understanding these differences, it's easy to turn a smart vacuum cleaner into a useless piece of plastic.
⚠️ Warning: Installing third-party audio packets may result in a loss of warranty.Manufacturers clearly monitor the integrity of the software and any interference with system files is recorded.
And then you have to consider the sound quality. Standard files are optimized for a robot speaker that doesn't have a high-quality playback. If you download a file with a high bitrate and a complex structure, it can sound hoarse or intermittent. Audio optimization is a key step that you can't ignore if you want the phrase to be clear, rather than turn into a porridge of noise.
Technical requirements and preparation of the device
Before you start downloading left-handed voice packets, make sure your hardware and software environment are ready to go. First, check your robot vacuum model. Third-party firmware support and the ability to replace audio files is relevant mainly for models running modified versions of Valetudoroot rights. Make sure the firmware version is not the latest, as new updates often close vulnerabilities used for modifications.
You will need a stable Wi-Fi connection at 2.4 GHz. Most Xiaomi robots do not support the 5 GHz band, which often causes errors when transferring large amounts of data, such as audio files. Also make sure that the device’s battery is charged at least 60% so that there is no sudden power outage during the process of replacing system files.
You'll need a Windows, macOS or Linux computer to run it, and you'll need specialized device management software like miio or vacuumz if you're going to work through the command line, and an alternative and simpler way to do that is to use the Valetudo web interface, which allows you to download files directly through your browser.
Special attention should be paid to the preparation of the audio files themselves. They should be in OGG or WAV format, because these are the formats natively supported by the robot audio subsystem. Conversion from MP3 may be required if you downloaded the finished "package" in a popular format. Use audio editors to normalize the volume so that the robot does not whisper or scream.
Search and preparation of sound files
Searching for ready-made "dumb" voiceovers is a task that requires caution and verification of sources. Most often, such files are distributed on enthusiast forums, in telegram channels dedicated to Xiaomi, or on specialized resources like GitHub. Search for "custom voice pack xiaomi", "funny voice xiaomi vacuum" or "russian voice pack". It is important to understand that downloading files from unverified sources carries risks: along with the voice in the archive may contain malicious code, although this is less likely for audio files, but the risk of damage to the file structure remains.
If you don't have a package with the right phrase, you can create it yourself. You'll need a microphone and a program to record and edit sound, like Audacity. Write down a phrase, cut the silence at the beginning and end, and apply the normalization effect. Remember, the robot speaker is narrow-band, so it's worth raising the frequencies in the 1000-3000 Hz range a little bit for better speech intelligibility.
💡
Use a bitrate of no more than 128 kbps for audio files. Robots have limited memory, and files that are too heavy can cause errors when downloading or playing.
Once a file is prepared, it must be renamed according to system requirements. Usually, voice packet files have specific names tied to language codes, such as ru.pkg or en.pkg, or hashed names. The exact name of the file depends on the installation method: if you use the DNS spoofing method, the name can be any name, but the link must lead to the correct file. If you copy files directly to memory, you need to know the exact name of the system file being replaced.
There is also the option of community-based pre-built packages, such as AndreySV or denki packages, which often include a set of humorous phrases in Russian. These packages are safer because they are tested by the community. However, "bullshit" versions are usually modifications of these builds and distributed separately.
Methods of installation of non-standard voiceover
There are several basic ways to introduce custom sounds into a robot system, and the easiest and safest method is to use the "Your Voice" function in the Xiaomi Home app (if your model and region support this feature), in which case you simply record a phrase through your smartphone microphone and it is stored in the cloud or device memory, but this method is limited by the length of the phrase and does not allow you to download a full audio package with many commands.
More advanced method - the use of DNS-The essence of the method is to configure the router or use a service (for example, VacuumZ or VacuumZ). DNS Changer, which redirects robot requests to the server with your files. When the robot thinks it's downloading a Russian language packet from an official server, it actually downloads your modified file with the right phrases.
☑️ Checklist before installation
The third method is direct file swaps via SSH or ADB. It requires you to get super-user rights on the device. You connect to the robot over the network, access the file system, and replace files in /mnt/UDISK/voice or similar, which gives you full control, but there is a high risk of the device being "buried" if you make an error in the paths or file formats.
⚠️ Attention: When using the method DNS-You can change the servers and make sure that the server you're redirecting traffic to is reliable, and that's where the file request goes, and in theory, the server owner can see. IP-For models that support the Valetudo platform, the process is simplified before you download a file through a web interface, you go to the Sound or Voice section, select a file on your computer and click Upload, and the system will check the format and write the data to the desired memory cell. This is the most (recommended) way for tech-savvy users who want to secure their data from the manufacturer's cloud. DNS Consider the most popular and relatively safe method of voice replacement – through redirection. DNS-request. This way you can swap the official language packet for a modified one without having to go inside the firmware code. DNS on a smartphone (for example, DNS Changer) or static setting DNS You can find a reliable source of modified voice packets first. Often, enthusiasts will link to files hosted on GitHub or specialized servers. URL-File address or use the finished configuration DNS, So, for example, the popular project valetudo has voice repositories: 📱 Open the Mi Home app and make sure the robot is online and available. 🌐 Launch the application for the change DNS on a smartphone connected to the same Wi-Fi network. ⚙️ Enter the address. DNS-server providing modified packages (or use a service pad). 🔄 In the Mi Home app, go to the robot settings, select Voice, and change the language to the one you plan to replace (usually Russian or English). ⏳ Wait for the language pack to load. At that point, the robot downloads your file instead of the official one. Once the boot is complete, the robot must restart the audio system. Check the result by sending a voice control command or starting a cleaning operation. If the robot spoke in the right voice, the procedure was successful, and if there was a standard error or the robot was silent, then the file did not fit the format or bitrate, and the procedure should be repeated with another file. If the robot is silent after changing its voice, try resetting the network settings (simultaneously pressing two buttons on the body). DNS. Then repeat the procedure by making sure the file has the correct OGG format and sample rate of 16,000 Hz. Alternative options and customization via Valetudo For robot owners who have completely switched to alternative Valetudo firmware, the sound installation process becomes part of the overall smart home ecosystem. Valetudo is an open-source project that allows you to control the robot locally, without the Xiaomi cloud. In this case, you get full access to the file system and can download any sounds through a convenient web interface. Installing Valetudo requires certain skills, but opens up huge possibilities for the robot to simply change the logic of the completion of the work, but you can not even change the "choices to the work" to the work. So, there's a Sounds section in the interface where you can upload your WAV or OGG files. The advantage of this method is that it's completely independent of the manufacturer's servers and fine-tuning. You can create your own voice pack by writing down phrases for each event: "I'm starting to clean up," "Stuck," "Bank full," "Back back to base." It gives you much more freedom than just finding a ready-made "mat" on the Internet. However, it's worth remembering that going back to Valetudo is a way back. It can be difficult, and sometimes impossible, without the tables, so that the basic methods are used, and the software is recommended that users understand the basic methods. This will help you choose the optimal path for your model and training level. Method Complexity Risk loss warranty Required skills Support models Record through the application Low No Basic New models (S6+, Mop 2+) DNS-Substitution of the average minimum PC user Most models Xiaomi/Roborock Replacement of files (Root/SSH) High High Advanced (Linux) Older (Gen) 1, S5) Valetudo firmware Very High Warranty cancelled Expert Limited List (Gen) 1-3, S5) As can be seen from the table, for most users, the optimal balance between the quality of the result and safety is the method. DNS-It doesn't require deep system intervention, and it's easy to reverse: just go back to the settings. DNS Automatic, and the robot will start to swing official voices again. 💡It is safest to use the temporary method. DNS-It allows you to set any voice, but it leaves no trace in the firmware after returning the standard network settings. Possible problems and their solution In the process of experimenting with sound, you may encounter a number of typical problems. The robot can start to play distorted sounds, stutter or even shut up. Often the reason lies in the wrong file format. Make sure you use mono-audio, as stereo files can be incorrectly processed by the vacuum cleaner's audio chip. Another common problem is a packet loading error: If the robot writes "voice update error" or simply ignores the command, check the file size. System constraints may prevent downloading files larger than the one in the file. 2-4 Squeeze the audio or reduce the length of the sentence. If the robot gets stuck in a reboot cycle after the sound is set, the system configuration file is likely to be damaged, and then the factory reset will help (10-15 (b) simultaneously pressing the power and return buttons, which will return all system files to their original state. ⚠️ Warning: Never interrupt the process of loading a voice packet by turning off the power. This can damage the memory partition where the sounds are stored, and require complex recovery through the console. Robot bought in China may not accept Russian voice packets even through substitution DNS, If its hardware audit is tightly tied to the Chinese region. In such cases, only changing the region in the application (which often requires a device reset) or using global versions of firmware helps (FAQ) Can you install a matte voice without losing warranty? Technically, using the method DNS-The switch does not change the device's permanent memory (flash), but only temporarily changes the source of the data. DNS, But the robot will work like a new one, but the manufacturer can refuse warranties if it detects that there's an interference, so technically, there's always a risk. Is it safe to download the finished voice packets from the Internet? Downloading audio files (.ogg,.wav) is itself safe for the computer, as it is not executable code. However, if you download executable files or scripts for installation, there is a risk of infection. Always check files with antivirus and only use proven sources with a good reputation in the community. What if after installing the voice, the robot stopped connecting to Wi-Fi? DNS. Try resetting the Wi-Fi settings on the robot (usually the return and power buttons). DNS In the initial setup phase, does my robot support recording your own voice? The Custom Voice feature is not available on all models. It has appeared in newer devices (series). S6, S7, Mop Pro and newer. For older models (Gen 1, S5) The only way you can replace the packages is through third-party methods. Can you get it back if something goes wrong? Yes, in most cases. If you have changed the firmware completely (for example, put Valetudo), a return is possible, but requires a re-flashing procedure to the official version, which can be a technically difficult process. 💡Before any experiment with the robot's file system, take screenshots of your current settings and write down the device's serial number, which will help restore access faster if you have problems with the binding.
