Show HN: Turn native language audio into flashcards and shadowing practice

Hacker News Top Tools

Summary

LingoChunk is a tool that converts native language audio into Anki flashcards and shadowing practice, supporting 15 input languages and over 30 output languages.

Here is a tool I built initially for myself to help with my German and Greek language studies. It started as a hack for creating Anki cards from native language audio. It extracts the words, finds their base forms (lemmas) and groups the examples by the lemma. At some point I realised that I have a transcription with word level timestamps that opens a lot of other opportunities. So I added a mode to click the first and last word in the transcript and it starts looping with the right gap and repeat count.<p>Another feature I use a lot is selecting an audio fragment, sending a predefined prompt to an AI to &quot;explain grammar&quot; or &quot;explain nuances of meaning&quot; and I still experimenting with prompts.<p>And because shadowing is so easy I also use it as a player to improve my English pronunciation. (I am not a native English speaker.)<p>I made a quick video showing the workflow for creating Anki cards and shadowing: <a href="https:&#x2F;&#x2F;youtu.be&#x2F;TaR58uuDBvU?si=o5aGLAi2S-BZ7Zy9" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;TaR58uuDBvU?si=o5aGLAi2S-BZ7Zy9</a><p>The app supports 15 input languages (Japanese and Chinese are the latest experimental additions), and more than 30 output languages.<p>I would really appreciate it if you could try it <a href="https:&#x2F;&#x2F;lingochunk.com&#x2F;try" rel="nofollow">https:&#x2F;&#x2F;lingochunk.com&#x2F;try</a>. I know there are other tools with similar functionality but I created something that fits my workflow and it is fun to build.<p>Also I struggled to find public domain audio for the try page. I&#x27;d be grateful if anyone could point me to public domain sources (I used LibriVox, Wikimedia and FSI courses), or if you&#x27;re a creator, let me feature some of your own recordings with credits and links.
