## Reset voice module
It is used to reset the [voice command module](https://docs.petoi.com/extensible-modules/voice-command-module), simplifying its [debugging process.](https://docs.petoi.com/extensible-modules/voice-command-module#how-to-debug-if-the-voice-command-doesnt-work) If the voice module does not respond to your voice, you can use this tool to reset it. It's pretty simple to use: click the **Reset voice module** button.

## Calibrate gyroscope

From version **1.2.4**, the interface has added this new function.
{% endhint %}
It is used to calibrate the gyroscope sensor on the mainboard. If you notice that the robot cannot maintain balance while performing skill movements (such as sitting down) and its body keeps shaking, you need to recalibrate the gyroscope. To calibrate the gyroscope, click the **Calibrate gyroscope** button.
