My mother uses her Dell laptop with an Ubuntu installed on it. It is usually great to maintain from my part, as all she uses is Chromium and the files explorer. I just update the software sometimes. But something that started happening in the latest versions of Chromium is driving me nuts. Every time I talk to my mother in my native language in front of the laptop, the "Ok, Google" functionality activates and starts the search of the "parsed" English sentence in Google. I tried to disable it but failed to find how.
