New voice and no slow speed
In the Spanish course there is a new man's voice that is quite unpleasant to listen to. Also, this new voice has no slow speed. If this is what Duolingo has become, I will quit the course because there is more frustration than learning. This started yesterday.
Do you mean that on the Listening exercise where there is usually a normal and a slow speed that the slow speed has stopped functioning? If that is the case please report that here:
Be sure to include the language and what section of the course this occurred on and whether it was on the web or Android, iOS etc. Or if it occurred on another kind of exercise please include that.
