I tried the speaking challenges but never managed to finish one conversation. I feel that the robot is too stingy on my pronunciations, with zero error tolerance. I know my pronunciation is pretty bad (that's why I'm practising it), but the robot keep pointing out my mistakes and never let me finish one sentence, and even cut me off if I have one second or so's hesitation. How am I supposed to improve my speaking if I'm never allowed to speak? I think even the most amateurish real world language tutors know letting the learners express themselves with mistakes. After a while the robot's "sorry I have been staying up late and can't understand a thing" reply gets really infuriating.
So I want to ask my follow Spanish learners, what has been your chance with the speaking challenges? Is it helpful, effective? Do you need to be a fairly good speaker before the challenges become useful, and should I take some less challenging challenges before I use this?
