when the app is reading out sentences, can u show which word of the sentence is being read, in a "karaoke" way? it may help relate the sounds that is heard to the written word of the sentence.
Well, this sounds like something that would be beneficial at an early stage of learning a language. The further down the tree you march, the speed should actually increase (and this karaoke feature be revoked) in order for you to get prepared to listen to a native speakers' pace.
agree. it may be still possible for the user to re-activated the feature, though.
I don't think it'll be much useful with the languages you can currently learn on duolingo, but if in the future other languages like chinese or hindi or arabic will be introduced, then it'll be a very useful feature indeed.
