This issue has been analyzed by Opera. Duolingo uses the Web Speech API to handle microphone input. The speech-to-text engine in the Chromium source code for the Web Speech API uses a specific service on Google's servers. However, API access to the service is limited to official Chrome builds. Other builds of Chromium aren't allowed to have the access keys to use the service, which is why it breaks in Opera. To make this work, Opera would have to write their own engine that uses a different speech-to-text service (that they write and provide themselves, or one from another company that they pay to use). Or, Duolingo would have to use a different method to analyze the speech to convert it to text.
@miyukiwork (123456w0rK:) (human+machine+human translation:) Anyone of those link expander apps shown in the screenshot are offered as an alternative in Google Chrome and Samsung Internet when a shortened link is on a .HTM page but unfortunately not in Opera and Opera Mini.
(Shortened links are very useful with YouTube.)
The last year was rather gross to me. A rich brother suing poor me for money, health problems...
Now I hope it turns for the better. I even bought a skateboard recently - it just sits hanging on my wall, scary thing with TWO shaky wheels...
Who knows how to learn to ride this deadly device?
