Key Features for Audiobook Generation
1. Direct File Drag-and-Drop Parsing
No need to manually copy and paste thousands of lines. Simply drag your PDF book, Word document, or plain text file onto our studio dropzone. Our backend document parser (/api/upload) extracts clean body text automatically, discarding headers and formatting clutter.
2. Long-Form Script Processing (Up to 10,000 Words)
Standard text-to-speech tools fail when processing long documents due to browser memory limits and socket timeouts. TextToSpeechH AI breaks long chapters into logical sentence chunks, synthesizes each section through neural vocoders, and merges them into a single smooth, uninterrupted audio stream.
3. Multiple Natural Narrator Characters
Choose from authentic male and female voices across English (US/UK), Hindi, Urdu, Spanish, French, German, Arabic, and Japanese for fiction and non-fiction book narration. Customize speech rate and vocal pitch to match the mood of your story.
4. High-Bitrate MP3 Audio File Export
Download your completed narration directly as high-bitrate MP3 files (audio/mpeg) compatible with iTunes, Spotify, Audible production software, and any offline audio player.
