Please offer a turtle option
The audio is way to quick, and in some situations sounds distorted. Its making it very difficult to learn the proper pronunciation.
Pro tip .. don't learn pronunciation from DuoLingo. Ideally, you should be listening to audio clips from actual native speakers to learn correct pronunciation.
DuoLingo uses a text-to-speech program. It is pretty good, but it is far from perfect, especially for reading kanji and some of the more complex sentences.
Hi, you're right. The turtle mode is available on the web page, through a PC. I use DL only in that way. Even there, some words are not always perfectly said but it is much better. I learn German, personally. Otherwise do you know www.forvo.com ? Extremely useful in order to listen the pronunciations of words in many languages. Essential, in fact!
I wouldn't recommend using Duolingo for pronunciation, especially for Japanese. If you want to practice speaking and pronunciation, go with Pimsleur. They use techniques like back-chaining (saying a word forwards at native speed, then backwards part-by-part) to teach pronunciation, which has the added benefit of training your ear. The website https://supernative.tv/ is also great because it uses audio from a variety of sources with different native speakers.
I enter the word on Google Translate to better hear the pronunciation. It can sometimes differ depending on context though, so be careful.
Google translate pronunciation is also machine-generated. Better than most, but still not human. I use Forvo instead, they use recordings of real people's voices, and if you cannot find a word (pretty unlikely, their database is amazing) you can register and request it, then a native speaker will say it. They even have whole phrases recorded.
