Like HiDeo, according to https://developer.mozilla.org/en-US/docs/Web/API/SpeechRecognition#Browser_compatibility , they do not support webkitSpeechRecognition.

But the real problem is that you are not getting hints to let you use your microphone. Double validation.
Always allow access to cameras and microphone:
- From the main menu, select "Settings."
- Select websites in the sidebar.
- In the "Media" section, select allow access to cameras and a microphone.
Ultimately, even if you get a microphone problem, you still cannot use speech recognition. If you really want to support Opera (and other browsers), you should consider using IBM bluemix or Googleβs new speech for text (in beta).
