I'm with Garyb here. It is not particularly good. And even a significantly lower price would be way too high.
It is simply nonsense that people learn the pronunciation the best just with listening and that the written part of a course is somewhat "detrimental" to learning. That is just the marketing talk. Garyb and Tarvos are right.
I did half of one Pimsleur a few years ago (Swedish) and I was totally unimpressed. I had expected something really good and this was a real disappointment. I see why it can be a great resource for a language with few such courses available, but that is simply not the case of French or other mainstream languages. I was unimpressed with the format, the amount of content, the dialogues, the lack of proper explanations. Really, it could definitely serve to some learners as a supplement but the price is rather elevated for that.
I can actually imagine myself learning tons of mistakes due to the Pimsleur approach. As was already mentioned, a learner without the explanation has to guess a lot and it is normal to just guess some stuff wrong. If you repeat the mistake over and over again, you'll just fossilise the mistake and harm your progress.
There are much better resources. As the correct pronunciation is the main point of this thread, I dare to suggest resources that:
1.have both the audio and written material. Learning the ortograph is simply much easier together with the pronunciation, there is no need to demonise it. It looks more complicated than the Spanish one but much easier than the English one and very regular.
2.The audio includes only the native voices. That is not the case of Pimsleur, as far as I remember
3.There should be the basic explanations. It is simply not true that people don't need them. Some people don't and do fine just with guessing from the audio. But most need stuff like the differences between e/é/è/eu pointed out.
4.There should be stuff to practice on, that means audio you can repeat after, dialogues putting all the rules in practice.
There are lots of options with various prices. Some are free (and a lot is piratable or available in better libraries), many have a very good price/value ratio, some are simply overpriced. Let's not forget that a Spanish speaker (even a non native one) can choose from a much wider spectrum of resources, including the monolingual ones.
A few examples of stuff I consider much superior to Pimsleur:
-overviews like this one
http://phonetique.free.fr/ or this
http://flenet.rediris.es/cours/cphon.html which look good, cover the basics, and can supplement any full course. Or this:
https://www.podcastfrancaisfacile.com/a ... ncais.html All this is much better than blindly following a non native audio
-Lingodeer: an example of a free tool with native audio. It is not too advanced and still in beta, but it is very good for an app and the native audio is a huge advantage over most free courses. You can often play it at different speeds, you can record yourself and compare.
-Phonétique Progressive: in the middle of the price range (amazon offers the beginner book for 28 euro) and it offers tons of excellent drills, audio, explanations. There is no risk you would learn something wrong and have to relearn it later and it is a resource for months of work. It is a supplemental resource and proud of it, it doesn't promise nonsense.
-Assimil: more expensive, if you buy the audio too (which is necessary for a beginner, in my opinion). But the content is great, everything is shown in the dialogues that are a pleasure to train with. The slower speed does have disadvantages but I think it is ideal for the pronunciation practice for beginners.
-any good coursebook with audio. People do just fine with the mainstream coursebooks, provided they are of good quality (which is less of a problem now than it used to be) and that the student really does their part (and that the teacher supports them in that and doesn't sabotage it somehow, if the person has a teacher).
People don't fail to learn the pronunciation correctly with most coursebooks because of the authors. Vast majority simply doesn't do all the drills and exercises, people rush to the more fun stuff. And let's not forget that the pronunciation and accent develops progressively. You need to learn the basics but then you need a lot of exposure and practice to really improve. The idea of many beginners that they'll get the one best resource and "learn the perfect accent" is naive. Pronunciation gets revisited in one way or another forever.
What I believe is the number one problem emerging in this thread: the demonisation of French. It is not significantly more difficult than most other European languages, you don't need to spend hundreds of euros to learn just the basics, and the pronunciation and ortograph will not be that much of a problem, if you put in the efforts. The myths are just discouraging the learners and making tons of companies profit from it. For example Pimsleur. Learning the first few hundred words, some touristy phrases, no grammar, that's possible with many tools for free. Really, French is an exception among the mainstream languages. When it comes to the others, I have never encountered such a wall of discouragement from the publishers, teachers, internet communities, and the general public. The paranoia is stupid and leads to lots of spending.
