Your voice
Read it yourself, from anywhere
Record passages in your own voice — playback uses them wherever they exist and studio voices fill in the rest. {{ bookRecLabel }}.
My AI voice
Clone your voice once — then it can read anything, even passages you never recorded. Powered by ElevenLabs (paid plan required).
Ready ✓
Get a key at elevenlabs.io → Profile → API keys. It stays on this device.
Read a page of the book aloud, naturally — about a minute is plenty.
…or pick “✦ My voice” for any character in the cast below.
{{ elStatus }}
Voice match — free, on-device
No account needed. Reads a few sentences of your voice, measures your pitch, and tunes the closest studio voice to sit where yours does.
Matched ✓
…or pick “≈ My voice” in the cast (Studio engine).

Voice cast
detected from the text — dialogue is voiced per character
Your browser is using basic system voices. For dramatically more realistic reading, open GR8books in Microsoft Edge (free neural “Natural” voices) or install Enhanced / Siri voices in your OS speech settings — GR8books auto-casts the best voices it finds.
No speech voices found in this browser — playback will be simulated silently with follow-along highlighting.

Pronunciation
Teach GR8books how to say the names it gets wrong. Spell the sound out — “Azhrakith” → “azh-RAK-ith”. Applies to every voice, including your AI clone.
