EbookAloud

Ebookaloud is an ebook to audiobook conversion service that uses the high quality, open source Kokoro voices for text to speech synthesis. The voices convey a wide array of emotional tone, completely different than the legacy robotic TTS voices.

EbookAloud has several strengths over its competitors. You pay a flat price per audiobook - no subscription or account required. EbookAloud is tailored to a professional audiobook experience -- the pacing and voice selection has been fine-tuned for optimal listening. Audiobooks are generated in the widely-supported m4b format, which includes cover art and chapter listings, and is perfect for playback in Apple Books, Audiobookshelf, and many other applications. You get to keep the content you generate, it's not locked up in the cloud.

The pricing model is straightforward and affordable, geared towards paying for text generation, hosting, and ongoing development efforts.
