    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. Another feature I use a lot is selecting an audio fragment, sending a predefined prompt…

    Hey HN. I’m Ivan, hacker from Ukraine. For about a year, I was working on Listenly — an app to listen to text content with OpenAI's natural-sounding text-to-speech model. At some moment, I realized that it would be cool to take all the public domain e-books and create audio versions for them. So I did it... kind-of. It would cost an immense amount of money to generate all the audio right away (OpenAI TTS costs approximately $0.84/hour of audio; 11labs, for comparison, is 10 times more expensive). So, I took a more gradual approach. I took all the metadata from the Project Gutenberg…

    Hello HN community! I'm excited to introduce a project I've recently launched: Oration, an iOS app designed to convert PDFs into audiobooks. This idea was inspired by my experiences as an engineering student with ADHD, struggling to engage with dense academic papers. Relying on Text-to-Speech tools, despite their robotic quality, was a workaround for me and others with similar learning preferences or challenges, such as Dyslexia. Recognizing the limitations of existing tools—difficulty with complex formats, inability to skip over citations or footnotes, and inadequate handling of tables,…
