"The Arabic actors are not talking, but singing."

Translation: Az arab színészek nem beszélnek, hanem énekelnek.

[sseager]

The verb that Duolingo taught before for "to talk" was "beszélget", which I used and it said I was wrong:

"Az arab színészek nem besélgetnek, hanem énekelnek."

What is the difference between these two verbs?

[Andreas305]

I would recommend to accept "beszélget" az well as "beszél".

The difference between those two verbs is a grammatical case called "Frequentative": an activity is happening not only once but furthermore. The modern english language kept only some relicts of it, while it is very often used in Hungarian.

But have a look at https://en.wikipedia.org/wiki/Frequentative.

There is also a chapter about the Hungarian language and its form of frequentative.

The inconsistencies in this course could be frustrating sometimes, but let's not forget that people are working on it for free and do an amazing job. So I hope they get it fixed soon, and meanwhile I want to say warm thanks to them.

"Beszélgetni" is to have a conversation, to have a chat. A social activity. "Beszélni" is the general word for "to talk".
