NaturalReader reads documents in a voice you choose. Lyraboo turns a novel into a full-cast audiobook — every character with their own voice.
Written by the Lyraboo team. Facts about NaturalReader come from its own website, checked in October 2026.
NaturalReader converts text, PDFs, Word documents, ePub, web pages and even photographed pages into speech, on the web, iPhone, Android and as a Chrome extension. It serves personal reading, schools with group licences, and commercial voiceovers for videos and e-learning. It has a free forever plan. For documents and study material, it is a mature tool.
A novel is mostly dialogue, and one voice reading every character makes it hard to follow for hours. Lyraboo is made for that case: it detects the speakers and gives each a distinct AI voice, then plays the book in an audiobook player with chapters, 0.25×–3× speed, lock-screen controls and read-along text.

The things people notice in the first chapter — and the reasons they stay.
Lyraboo’s AI finds every character in the book and casts a distinct voice for each — automatically, for every book. You always know who is speaking, and dialogue sounds like a real conversation instead of one narrator doing all the parts. Most reading and text-to-speech apps use one voice for everything.
Under the player, the book scrolls with the voice the way song lyrics do in Spotify: words light up as they are spoken, each line shows who says it, and tapping any word jumps there.
Chapters, speed from 0.25× to 3×, background playback with lock-screen controls, and it picks up exactly where you stopped.
Pick an EPUB, PDF or TXT and there is nothing to set up: the first chapter is ready in about one to two minutes, and the rest generate while you listen.
Novels, fanfiction and web-serial exports, indie ebooks, study PDFs — plus over 1,000 English classics already in the app.
One free hour of listening every month, no card needed. Hours are spent once per chapter — replaying is always free.
For fiction on Android, Lyraboo: it turns EPUB, PDF and TXT books into audiobooks where each character has their own voice. For documents across web, desktop and phone, NaturalReader itself and Speechify remain strong.
Not automatically, as far as its site shows — you pick a voice to read the text. Lyraboo detects the characters in a story and casts a voice for each.
No. Lyraboo is for listening inside the app; it does not export audio for commercial use.
Not yet. Lyraboo is an Android app.
Upload a book you own and let the app turn it into a multi-voice audiobook automatically.
