AuroraBook vs Audissey

App to convert epub to audiobook using Text To Speech technology locally. No cloud, no subscription, no ads. Free.

Audissey turns web fiction into audio you can listen to anywhere — on your commute, while cooking, or with the screen locked. Open a chapter in Audissey’s browser and tap Extract, paste a link from Royal Road or a similar site, or paste the text yourself. Audissey imports the story, cleans it up, and reads it aloud. Build a personal library, organize stories on shelves, and pick up right where you left off. LISTEN YOUR WAY • Import from a link, pasted text, or the in-app browser — open the chapter, then tap Extract • Add a new chapter to a novel you already have, with its own title and number • Play, pause, and skip chapters with lock-screen controls • Tap Read on the player to jump back to the chapter and follow along • Adjust playback speed to match your pace • Read-along mode highlights text as it’s spoken • Ambient listening screen for a calm, hands-free experience SMART LIBRARY • Auto-import checks for newly published chapters • Automatically split massive, single-page stories (like Project Gutenberg books) into manageable chapters • Search across stories and chapters • Organize novels into custom shelves • Track read progress chapter by chapter • Syncs seamlessly across devices BUILT-IN AUTHOR SUPPORT When a chapter includes a Patreon or PayPal link, Audissey shows it in the reader so you can support the author. Those links stay out of the audio, so they never interrupt the story. INTELLIGENT, EXPRESSIVE VOICES Choose Apple’s built-in voices or switch to Audissey Neural Voices, our on-device neural voice engine. Standard speech synthesis runs on your iPhone, so your stories stay private. • Context-aware pronunciation: words like “read” are spoken the way the sentence means them • Dynamic expression adds emphasis and pacing to action and dialogue • Custom dictionary for character names and world-building terms • Assign a narrator to each story from its settings Audissey Neural Voices currently support English. More languages are in progress. ADVANCED API INTEGRATIONS Connect your own API keys on your device: • Speaker detection: use an OpenAI, Gemini, or Anthropic key to identify who is speaking. Chapter settings list the speakers in the chapter you’re reading, and a voice you assign is used for that character throughout the novel. • ElevenLabs: stream realistic, multi-cast character voices into your listening queue. AUDISSEY PRO A one-time purchase. Pro removes ads, lets you import unlimited chapters at once, and adds Cache Ahead so Audissey Neural Voices can keep playing smoothly with the screen locked. Audissey is for readers who want to hear their favorite stories — not another streaming subscription.
