I haven’t tried it yet but I read in a similar post about Language Transfer.

It’s FOSS and they have an app. The languages are limited in number but most main ones are there (except Italian!).

It’s basically recordings of lessons that you pause and repeat back, which sounds crap but seems to be done really well. The recordings are stored on several platforms for preferred access.

It has a music theory intro as well, which is why I’m sitting on it.

If you want to learn a language, surround yourself with it. Watch shows, play games, read articles, change language of your phone. If you don’t understand something, translate it. Use it. Apps are just empty practice if you don’t apply it

Human languages or programming languages? (I find it amusing that there’s one comment here assuming the former and one assuming the latter.)

Duolingo.

Duolingo was mentioned.

But one of the good things about AAA games is that they’re often voiced and captioned in multiple languages.

So, after picking up some basics – give a new player + playthrough of something you’re already familiar with in a new language.

I used Dreaming Spanish, which uses natural comprehension and teaches entirely in Spanish, with no translation. It’s not as fast as some alternatives, but it matches my learning style, and has given me a neutral accent when I speak

The usual, some introductory books and then some more advanced for my needs. As an actuarie, the languages more useful for me were R and Python, I chose Python because is more versatile for things beyond data sciences. If you said your specific needs, maybe someone can give you a guide from where to start.

Usually the best resources you can get online for free for language learning as a beginner or intermediate is mostly pirated photoscanned books, with some online pages or YouTubers mixed in as another supplement.

For example, for Japanese, I pirated the 3rd editions of Genki 1 & Genki 2, plus the workbooks for them. I also owe a lot to the YouTuber Tokini Andy (who has videos going over the updated Genki textbooks and explains a lot of things missing/poorly explained in the book, he’s pretty great). There’s also an interactive quizzing website for Genki someone made. For definitions and stroke order I used jisho.org, and for etymology I used Wiktionary, hanziyuan.net, and dong-chinese.com. The only other website/app I regularly used was Renshuu (a spaced repitition learning app for Japanese), which was pretty great and was a good supplement for drilling in what you learned from other resources – although you have to modify the settings quite a bit to really “optimize” it. A lot of people use WaniKani which is kind of similar but I think more Kanji-oriented and used more for students studying before a test. Oh and to learn the Kana, I basically just tested myself writing down the characters in the standard order for a few days until it got drilled into my head, I also used the Tofugu Hiragana learning resource thing but it only helped for a few mneumonics. Other than that, although I’m not exactly a weeb, I tried to force myself to watch anime (in Japanese) any time I wanted to do something like watch a show or play a game, and I’d look up all the stuff I didn’t recognize. Anime isn’t exactly representative of how Japanese people speak at all, and you’re going to get your shit kicked in (by that I mean disapprovingly stared at) by Japanese people if you speak like an anime character, but I suppose it’s like learning English off of Sesame Street and SkyDoesMinecraft…

For German, I heavily utilized Deutsche Welle’s learning resources, especially Nicos Weg. I also had people to practice the language with. My German still sucks though… for whatever reason, I had the absolute most difficult time with trying to learning German out of any language. The word order magic fucked with my head especially, but I just kept mixing up basic words.

For Russian I used Memrise at first, which worked for vocabulary and got me familiar with the most very basic vocabulary, but the features locked behind monetization eventually got too disruptive so I spent pretty much all my time on (pirated) beginner Russian learning textbooks and very technical grammar books (I was a very learned linguistics major so learning from linguistics-heavy books was significantly more feasible for me than it is for the average person). I probably had the least frustrating time with Russian out of any of the languages I self-studied. I self-taught myself Cyrillic when I was like 8 because I thought slavic stuff was cool so that didn’t really require any time…

I learned passable French in high school (despite my ADHD ass not paying attention 99% of the time and basically just not being present mentally for all of French 3), which then degraded a lot in my ability to use it since I never used it and was preoccupied with other stuff, but I can still read it fine, and I can understand it spoken depending on how they speak and my state of mind. I didn’t even study outside of school or anything really, I just had a teacher from France (she was my favorite teacher). Actually thinking of the words and grammar I’m trying to say though, I’m pretty fucked in that department unless I go back and practice it. French is my 2nd language.

I self-studied Spanish after school, not very seriously though, I could already grasp it pretty well enough because of my French knowledge. I got conversational in no time – still, randomly not being able to recall random words is a pain in the ass (that goes with English too I guess). I did a bit of Duolingo at first but then just started listening to podcasts and videos and stuff, and looked up the words I didn’t know (beforehand and during the time I was already doing a lot of Spanish linguistics work so I already knew “about” the language and its phonology/spelling to pick out the things I heard). This was really only possible because, again, I was already able to understand pretty much all the French you would encounter in daily life.

I tried (and failed) to learn Arabic a reeeally long time ago. It didn’t extend much past a few obscure and not-very-helpful learning internet resources plus Duolingo (which was kind of useless for Arabic, even moreso than Duolingo typically is useless for languages). I had an unusually hard time with the script for this one (is it racist to say the damn squiggly lines all look the same), and reading it without vowel markers is very difficult to me.

Right now I’m using this book online for Italian that’s only in Italian which is basically like, introducing grammar & topics in the language with no actual instruction or anything, it’s just a bunch of Italian sentences with images and stuff to get you to remember the grammar based off of context. It’s sick as hell, but I can’t remember what it’s called right now.

After a long time (around B2 or maybe B1 level probably) you have enough comprehension to start learning well while watching content made for natives – e.g. you can watch YouTube videos or a TV show in the language and can learn from looking up the (still large) portion of words you don’t understand.

I was originally a monolingual English speaker – only 1 native language, I didn’t have like 2 or 3 native languages like most of the world (shout out to all the kids who acquired English solely off of TV and YouTube as a kid). On one hand, being monolingual definitely makes you more ignorant to other languages and your first language might be a little bit harder (but honestly it doesn’t get much easier from there, you will still writhe in pain 4 hours a day trying to learn any subsequent languages), but on the other hand being a monolingual ENGLISH speaker opens you up to way more possibilities (resources) than not being an English speaker, so I guess overall I was pretty lucky in that regard.

I have really bad ADHD and Aphantasia which is (for the most part) a hinderance to language learning – my working memory is extremely bad, I can’t visualize SHIT and ADHD makes my non-visual memory go kaput. Language learning takes significant time, energy, it’s frustrating as fuck, and most of this comes down to a lot of it just being brute forcing memory. There is no cheat to language learning, there is no “lern basque in 23 dayz”, it is just putting thousands upon thousands of hours of very regular, very (inter)active focus and memorization methods into it until it’s drilled in your head. It can be more challenging than any job you’ve ever done and you’ll want to cry due to how little progress you feel that you’re making despite the great amounts of time and energy you put into deciphering this mess.

On the other hand, I know Autistic people with Hyperphantasia and Synthesia (specifically, the kind where you see colorful words appear in your vision when you hear, read, or think about language) and they are SIGNIFICANTLY more capable at language stuff than anyone else, although it’s still a lot of effort to put in for them of course.

I’ve been learning Chinese for about 6 months now. The key to learning a language IMO is that you need motivation (ie. a reason to want to learn), and something that immerses you in the language. For me it’s because I started dating a Chinese girl. I learn her language to help ease the communication between us, and to learn more about her culture.

Funnily enough, it started out as me doing the first few Duolingo lessons in secret to impress her between our first and second dates. But as our dates kept going well, I kept doing the lessons in my spare time. I didn’t originally set out to reach a point where I can have a full conversation with her over texting in Chinese, but that’s where we are now. Although to be clear I have to look up the stuff she says to me in my dictionary a lot. But then I can usually respond without needing to translate anything other than maybe some content words. The other day, I actually caught a typo she made and corrected her, which made us both laugh.

Currently learning dutch through Memrise on my phone and spaced repetition on obsidian.

Its slow going due to being swamped in school work. But i’ve found it more effective than my highschool french class ever was.
