Common questions about AI audiobook creation

Premium models like Tortoise TTS, Orpheus, and StyleTTS 2 achieve human-level quality in blind listening tests. While the very best human voice actors still bring unique artistic interpretation, AI narration is indistinguishable from professional recording for most listeners.

A typical 80,000-word novel (about 10 hours of audio) takes 2-4 hours to generate with premium models via the API. Fast models like Kokoro can generate the same book in under an hour. This compares to 40-60 hours of studio time for traditional recording.

Yes. You have multiple options: choose from 100+ built-in voices, clone custom voices from audio samples, use Parler TTS to describe each character's voice in words, or use Dia TTS for natural two-character dialogue scenes.

Audible (ACX) accepts AI-narrated audiobooks. You must label them as AI-generated. Our output meets the technical requirements (WAV, proper sample rate and bit depth). Check Audible's current policies for the latest guidelines on AI narration.

Traditional audiobook production costs $2,000-5,000 per finished hour (voice actor, studio, engineer, editing). AI narration with TTS.ai costs roughly $5-50 per finished hour depending on the model. That is a 95-99% cost reduction.

Yes. Record 10-30 seconds of the author reading, upload it, and generate the entire audiobook in their voice. Models like Chatterbox, GPT-SoVITS, and OpenVoice provide high-fidelity voice cloning. Longer reference audio (30-60 seconds) produces better results.

GLM-TTS has the lowest character error rate among open-source models, making it best for accurate pronunciation. For unusual names, you can use phonetic spelling in the text or SSML tags (where supported) to guide pronunciation.

Generate each chapter as a separate audio file. This lets you review and regenerate individual chapters without reprocessing the entire book. Add silence between chapters in post-production and include chapter markers for Audible and Apple Books distribution.

Yes. CosyVoice 2 supports 8 languages with voice cloning, and GPT-SoVITS covers 4 languages (English, Chinese, Japanese, Korean). You can produce multilingual editions of the same book while keeping the narrator voice consistent across all language versions.

Process 1,000-2,000 characters per request for the best results. This keeps each audio segment consistent in quality and pacing. The API supports batch processing so you can automate splitting and generating an entire manuscript sequentially.

Yes. Use one voice for narration and switch to different voices for character dialogue. Process narration and dialogue segments separately, then combine them in an audio editor. For two-character scenes, Dia TTS generates natural back-and-forth dialogue.

Use the same model, voice, and settings for every chapter. Generate all chapters in the same session or API batch to maintain identical audio characteristics. Normalize the volume levels in post-production for a uniform listening experience.
