After months without any updates, our Huawei P20 Pro has just received a rather large update including two security patches, the addition of Huawei AI Voice, also known as “Celia”, as well as the addition of various new Huawei applications, found bundled in the “Huawei Apps” folder.

One of the bigger changes brought by this update is the addition of Huawei’s own voice assistant, AI Voice, commonly known as “Celia”. Launched in mid-2020 in Europe, it was originally only available in three different countries and languages, being Spain (Spanish), France (French) and the UK (English), while this new version also supports Arabic, US (English), Germany (German), Italy (Italian), Malaysia (Malay) and Poland (Polish). More languages and regions will probably be added over time.

By default, Celia replaces Google’s voice assistant, and is launched by either saying the wake-up phrase “Hey Celia”, or by holding the power button for 1 second. To turn off the phone, users have to hold the power button for longer (typically 3 seconds), ignoring the voice assistant. This feature can be disabled through the device settings by going to “Settings” and typing in the search bar “Huawei Assistant” and selecting “AI Voice” or directly looking for “AI Voice”. To disable Celia, tap on “Wake with Power button”, and press the toggle. Alternatively, users can switch the voice assistant back to Google’s.

This new update changes the version from CLT-L29 to CLT-L29 and is 775 MB in size.
