Change Voice Command Language auf Huawei
Voice control on Huawei phones keeps a single active language, chosen automatically during the first device activation. It does not update on its own when you later change the system language or switch regions, which is why commands can suddenly go unrecognized.
To change it, open Open the settings ➔ Tap on Accessibility features ➔ Tap on Voice control ➔ Tap on Voice command language. From the list, tap the language you actually want to use for spoken commands, then confirm the switch with Confirm with Change.
This setting only affects how the phone interprets your spoken commands, not the overall interface language. If menus and apps are still showing the wrong language, that is a separate setting and needs to be changed in the general language options instead.
No reset or reboot is required. The new voice command language applies immediately, so you can test it right after confirming the change.
