Introduction: Why change the voice of a robot vacuum cleaner?
Xiaomi’s robot vacuum cleaner voice prompts are not just a functional element, but part of your daily interaction with the appliances. A standard female or male voice in Chinese/English can be annoying, distracting or simply not fit into the atmosphere of the home. Fortunately, most Mi Robot Vacuum, Dreame and Viomi models allow you to change voice packets — officially or through alternative methods.
In this article, we’ll look at all the current ways to change voice, from standard settings in the Mi Home app to manually stitching custom voice packs, which models support this feature out of the box, and which will require unlocking potential through third-party tools, and we’ll also warn about the possible risks and give recommendations for choosing alternative voices, from Russian-language announcers to funny characters from pop culture.
Important: the procedure varies depending on the firmware version, the region of purchase of the device, and even the serial number. If your vacuum cleaner is purchased in China, you will have more options for customization than the European versions with limited functionality.
