Why do some languages have microphone exercises and others don't?
Is there any way to fix this? I've been a part of the Polish course for some time now, and it has never asked me to speak; unlike the French course, in which I used the microphone during the first lesson.
As far as I know, speaking exercises are fully dependant on whether the Duolingo team implemented sound recognition software for given language or not – there is nothing the course contributors can do about it.
In other words, the only thing that can 'fix it' is patience. ;-)
