Lectures and Narrations

Free · Designed for iPad. Not verified for macOS.

Multi-voice audiobooks that read along with you — the EPUB reader highlights each narrated sentence. AirPlay & Google Cast. No accounts, no tracking. Lectures and Narrations — a player for enhanced, multi-voice .m4b audiobooks on iPhone and iPad, with an EPUB companion reader that highlights the text in sync with the narration. PLAYER • Chapter-relative scrubbing with a whole-book progress strip and live time remaining. • ±10/30 s skips, previous/next chapter, tappable chapter list. • Pitch-preserving 0.5×–3× speed, remembered across launches. • Background playback with full lock screen and Control Center support. • Mini-player on every screen — skips, chapter and book progress, and a Read shortcut. • Auto-saves your position and resumes where you left off. CAST ANYWHERE • AirPlay and Google Cast, side by side — stream to any speaker or TV while the sleep timer, reader sync, and progress saving keep working. READER + SYNC • Attach the matching EPUB and a sync manifest, and the text highlights itself in sync with the audio, scrolling and turning pages as you listen. • Manual paging pauses following; Resume jumps back to the narrated line. • Whole-book text search with in-place highlighting. • Light/dark mode and adjustable text size, both remembered. LIBRARY • Import .m4b audiobooks from the Files app — or AirDrop a book to your device and it imports itself. • Covers with progress bars; folder-style collections you can arrange by hand. • Finish a book in a collection and the next one is offered by its cover. IMAGES • Every illustration embedded in the audiobook, in a gallery with pinch zoom — and as tappable markers on the player scrubber. SLEEP TIMER • By time or by chapters, with volume fade-out, postpone, and shake-to-postpone. 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, 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: this app — built specifically to play those enhanced audiobooks.
