Lectures and Narrations

About this app

An Android player for .m4b audiobooks — with chapter-relative scrubbing, sleep timers, and an EPUB companion reader that highlights the text in sync with the narration

One ecosystem, two halves
LN began as an AI experiment in book understanding — using language models to analyze narrative structure, character traits, and scene dynamics — and grew into an end-to-end pipeline for immersive, multi-voice audiobooks.

ln-vox - The Creator
An offline, self-hosted AI pipeline that ingests raw text or EPUBs. It orchestrates LLMs to cast characters and direct emotional delivery, then uses local TTS to generate a fully acted, multi-voice .m4b complete with text-to-audio sync markers.

ln-reader - The Consumer
A custom Android app built specifically to play these enhanced audiobooks. Chapter-relative scrubbing, sleep timers, and an EPUB companion reader that automatically highlights the text in sync with the audio.
