No slow button
Listening exercises in the Hungarian course are making me sad. When the TTS speaks rapidly, I often cannot catch which sounds are long and which are short, because in my native language the sound's length does not matter. In this course there is no slow button, that's why I make a lot of mistakes. In other courses this button used to help me a lot. Is there any chance that it will appear later?
Let's hope so. But the audio in this course was recorded with a real human being. So it is not as simple as slowing down the voice generator. But it is easy to figure out the length of a vowel in Hungarian. If you see a little line, or lines, above them, they are long. In all other cases, they are short.
And about long vowels: it is clear when I see the text, but it is difficult to me to hear the long vowels in an unfamiliar word and to spell it correctly in the listening tasks. Duolingo forgives the spelling mistakes, but I would like to connect the spelling and the sounding of the word at once.
It might be good to keep a few things in mind:
The differences between a / á and e / é are easy to hear for most people - it's not (merely) length, but an actual change in the quality of the vowel. So they won't cause you much trouble.
There is no audible difference between i / í so you will never be able to hear that one - you just have to learn the spelling.
A great deal of any normal Hungarian sentence is built from endings and patterns that recur over and over. So you'll learn quickly that tól at the end of a word is always long ó and you won't have to think much about it, or listen carefully for the difference. There will only be relatively few "root cases" where you really have to remember something (or listen for something in a new word).
It's not just you. Have a look at this list of common errors (committed by Hungarians) in Hungarian writing:
You'll notice there are many errors involving short/long vowels and double/single consonants.
