RadioBook uses next-generation AI to narrate your books with real emotion, natural pauses, and storytelling depth — indistinguishable from a professional voice actor.
Our AI doesn't just read — it understands context, emotion, and narrative arc before speaking a single word.
Our model analyses the full book structure — detecting dialogue, tension, humour, and pacing before generating a single word of audio.
Tone, cadence, and breath patterns adapt in real-time. Dramatic scenes feel tense. Tender moments feel warm. Comedy lands naturally.
Choose from authentic regional accents. Each voice is crafted from thousands of hours of real human speech recordings.

Every feature exists to make you forget you're listening to an AI.
The AI detects joy, grief, suspense, and humour — and mirrors that emotion in tone, tempo, and cadence the way only a skilled actor can.
Adaptive ToneStrategic micro-pauses before dramatic reveals, breath sounds between long passages, and paragraph silences that feel completely organic.
Breath ModelingSwitch between Fiction, Non-Fiction, and Poetic modes. Fiction mode automatically differentiates character voices from narration.
