I'm looking for website to learn me pronunciation free and learn french beside of duolingo.
Vorvo.com is a website that has a bunch of native speakers of many languages pronouncing words, just type a word in a listen, French is a popular language so there will probably be a few different people pronouncing the most popular words which is also good to get used to different voices saying it. Good luck with your French studies :)
In addition to the websites provided, which are great resources, you should check out the band La Femme. Their most recent album mystere is quite good and there's like 16 songs I think. I know that it is not a website and therefore not a direct answer to your question, but you will get the lyrics stuck in your head and it gives you an innate feel for how the language sounds.
