Hey HN, it’s been 8 years since I posted on here about the launch of my Japanese dictionary app Nihongo [0] and I’m finally back with a new app: Nihongo Lessons! Think of Nihongo Lessons as the textbook to Nihongo’s dictionary. It’s an app for learning Japanese, specifically made for learners who are serious about becoming fluent, and want a guided set of content that will help them efficiently acquire vocabulary and grammar. The project came about when Adam Shapiro of Japanese Level Up (Jalup) [1] announced last April that he was shutting Jalup down. As a fan of Adam’s work I was bummed to…

Built this because tones are killing my spoken Mandarin and I can't reliably hear my own mistakes. It's a 9M Conformer-CTC model trained on ~300h (AISHELL + Primewords), quantized to INT8 (11 MB), runs 100% in-browser via ONNX Runtime Web. Grades per-syllable pronunciation + tones with Viterbi forced alignment. Try it here: https://simedw.com/projects/ear/

Hi HN, Just wanted to share a tool i've been working on to help with my own study routine. It’s a browser extension called Lingoku. The idea is simple: we spend hours browsing the web in English every day. This tool replaces some of the english words with Japanese vocabulary based on your japanese level (Similar to Toucan, but with a better user experience). It’s basically an attempt to make the "i+1" method actually passive, you understand the sentence because it's mostly english, but you pick up Japanese words naturally from the context. It uses an LLM in the backend to make sure the…

Hello Hacker News, When learning foreign languages, I made the most progress by speaking them throughout the day, every day. So I made a site where you can *speak* to an AI language teacher to practice both listening and speaking. # The product *What I have now:* * Multilingual speech recognition: You can ask a question in English and get an answer in your target language. * Feedback on your grammar. * Suggestions: See examples of what to say next to keep the conversation flowing. * Speed: Choose a lower speed for beginners or a faster one for advanced levels. * Translations: Click to see a…

Hey folks! I'm Callum, and I'm working on a way to practice a new language with an AI powered tutor. I've always found that the hardest part of learning a new language is finding someone to actually converse with. Even if a partner can be found, the pressure can mean that you are more focused on not making mistakes than on actually learning new grammar or vocabulary. The service that I have been working on allows you to practice with a language tutor via online chat messages, or you can have a turn-based voice conversation. I'm working on a number of other features that will be coming out…

Actually, it is yet another tool to learn a language through immersion (classic set of features, watch on youtube/netflix, read a website or book). It has a popup dictionary so you can click on a word and it will show the definition. Nothing new in that regard, except that it has been made with only Korean in mind and does not plan to extends to other languages. I was learning and still am learning Korean (now using my own tool to learn!). I initially made the tool for myself because none of the tools out there could correctly figure out what a word was in the text. And that's where the…

Recently moved to Egypt, and in dire need to get the numbers down. Great excuse to explore learning software some more. Possibly very niche, but maybe it is useful for someone else out there. Feedback is always welcome.

Hi HN, I’m Pablo, I built this application to learn languages using podcasts: https://www.langturbo.com (No signup required) There are a lot of tools to learn languages, but most of them focus on beginners (understandably so, that’s where the money is) but not many exist that target intermediate or advanced learners. The ones that exist make you find content on your own and then import that into their apps, which can be tricky when you don’t know where to look. LangTurbo has a unique curated database of podcasts by language (some even have dialect labels) that you can browse by…
