Sandbook is a realistic on-device text-to-speech (TTS) model that converts your input text into emotionally natural speech. You can use it to read ePub books, PDF, or TXT files. You can also use it to generate short speech samples and export them for further use. Import EPUBs, PDFs, or TXT files and listen with your choice of dozens of natural-sounding voices, including British and American accents in both male and female options. Read webpages aloud, convert any text to speech, and download audio files for on-the-go listening. No cloud processing, unlimited usage, user-friendly interface, and complete privacy protection - everything happens right on your device. ■ FAQ 1. Why doesn't it support background/screen-off reading? Because it runs a large model on your device, Apple forbids apps that use high GPU/VRAM from running in the background. 2. Is it normal for my phone to heat up or sometimes even crash during use? Heating up is normal because the app is utilizing your device's GPU. If it crashes, this indicates that your device has low memory (3GB or less), which may happen on iPhone SE or older models. 3. What languages does Sandbook support? Sandbook currently supports English (US/UK) voices with both male and female options, delivering exceptionally natural pronunciation and intonation. 4. About privacy All your data stays on your phone and never leaves your device. ■ Support https://sandbook.app [email protected]
