How to Teach Xiaomi’s Robot Vacuum to Speak: From Standard Phrases to Custom Voices

Voice alerts for robot vacuum cleaners are not only a convenience, but also a way to make cleaning more interactive. Xiaomi Mi Robot, Dreame and Viomi models support voice notifications about the start/end of cleaning, errors and battery status, but by default this feature is often disabled or works in Chinese. In this article, we will analyze all ways to activate voice — from official settings in Mi Home to manually stitching alternative firmware with support for Russian.

Many users face a problem: the vacuum cleaner is silent, despite the manufacturer's promises, and the reasons can be different, from regional restrictions to outdated firmware. D9 viomi V3, So you can choose the best option without the risk of "bricking" the device.

If your vacuum cleaner doesn’t support voice alerts initially (like the first-generation budget versions of the Mi Robot Vacuum), don’t get upset. There are workarounds to go from connecting external speakers to using them. TTS-Text-to-speech through home automation, and the key is to identify the model and version of the firmware correctly.

We warn you beforehand: some methods require unlocking the bootloader or installing unofficial software. This may deprive you of warranty, so carefully assess the risks. For most users, standard in-app settings will suffice, and we will consider them first.

1. Verify support for voice alerts with your model

Not all Xiaomi robot vacuum cleaners can talk, voice notifications depend on the hardware platform and firmware version. Here's how to check compatibility:

First, look at the box or sticker on the bottom of the device. Voice-enabled models usually have a Voice Pack or a Voice Pack. TTS (Second, check the list of compatible devices:

• 🔹 Supported by default: Mi Robot Vacuum-Mop 2 Pro, Dreame D9/D10, Viomi V2/V3, Xiaomi Mi Robot Vacuum-Mop P
• 🔸 Requires firmware for activation: Mi Robot Vacuum 1S, Mi Robot Vacuum-Mop Essential, Dreame F9
• ❌ Mi Robot Vacuum (first generation), Mi Robot Vacuum Lite, most OEM-modelling

If your model is on the first list, go to the Mi Home section about setting up. If the second one requires a firmware update (more on this below).

2. Voice activation via the official Mi Home app

The safest way is to use the standard settings in the Mi Home app (or Dreamehome/Viomi The instructions are suitable for most modern models:

1. Open the application and select your vacuum cleaner.

2. Go to Settings → Voice Alerts (or Notifications) → Speech tips).

3. Activate the slider Enable voice notifications.

4. Choose a language: if there is a Russian option, install it. If not, try English (sometimes works better than Chinese).

In some firmware, additional options are available:

• 📢 Volume (adjustment from 1 to 10)
• 🔕 Notification types (start cleaning, end, errors, low charge)
• 🎤 Voice Assistant (Integration with Alice or Google Assistant)

💡

If the application does not contain the item "Voice alerts", update the vacuum cleaner firmware through Settings → Software update: Sometimes the function appears after the update.

Problem: Even after activation, the vacuum cleaner may be silent.

• 🔇 Disabled speaker in settings (check Settings) → Sound)
• 📵 Vacuum is not connected to Wi-Fi (voice packets are downloaded from Xiaomi servers)
• 🔄 Regional restrictions (if the device is linked to a Chinese server)

3. Change the region of the voice unlocking device

Many Xiaomi models come with a reference to the Chinese region, where voice alerts work only in Chinese. To unlock other languages (including Russian), you need to change the region of the device in the application.

Instructions for Mi Home:

1. Open the device profile in the application.
2. Click on the three dots in the upper right corner → Settings.
3. Select a Region and change to Russia, Europe or the United States.
4. Restart the vacuum cleaner (hold the power button for 5 seconds).

Important: After changing the region, you may need to re-assign the device to the account, and some functions (such as cleaning cards) may temporarily disappear, they will recover after synchronization.

For the Dreame and Viomi models, the process is similar, but their proprietary software is used:

2. Create a scenario: when an event from a vacuum cleaner (for example, start_cleaning) launch TTS-columnist.
3. Set up the text of the alerts (for example: "Vaccines have started cleaning the living room").

Method 3: Replacement of the speaker (for technically savvy)

In some models, the Mi Robot Vacuum 1S, Dreame F9) You can physically replace the speaker with a more powerful speaker and plug it into the motherboard:
