I love the Russian course and I think it’s great overall, but the audio is terrible. I’m not particularly good at speaking Russian, but even I at my very elementary level have spotted a ton of errors in the pronunciation.
The most common errors are mispronouncing “е” as “ё”, such as the word “все” being mispronounced as “всё”, and words that are accented on the wrong syllable, typically changing them to a different word that often is grammatically incorrect and makes it a nonsense sentence. For example in one exercise it recently mispronounced the adjective “друго́м” (masculine or neuter prepositional case, meaning “other”) as “дру́гом” (masculine instrumental case, meaning “friend”) and it does this sort of stuff all the time.

Another, “пора́” (a noun meaning time, often used to mean “it’s time”) is mispronouced “по́ра” (a noun meaning “pore”.)
I am virtually certain that there are far more errors than I have reported or even noticed, because I’m pretty terrible at Russian myself and I am only able to detect the errors in the most common words that I have already mastered.
The prevalence of the errors also makes me extremely skiddish about continuing in the Russian course (or about recommending it to others) because I absolutely want to avoid creating a bad habit of hearing and internalizing a word with the wrong pronunciation. Learning things wrong and having to unlearn them is terribly inefficient and I think something it is important to avoid. It always takes me longer to unlearn something than to learn it. And it would probably take far less time for one person to fix all these things, than it would take for everyone taking the course to have to unlearn these things after the fact.
I would strongly prefer if the audio could be gone over, every sentence by a native speaker, and corrected, so that the course can be actually useful for us to practice and won’t be setting us up to have to unlearn things later.
