What is Speechdub?
Speechdub is a document listening tool that converts PDFs, web pages, and pasted text into audio using natural AI voices. Users import content, choose a voice character and playback speed, and follow along with sentence-by-sentence highlighting as the document is read aloud. While listening, users can ask questions about the content by voice or text and hear the answers read back. A built-in skip-sentence feature lets users mute citations, repeated instructions, or code blocks without editing the source document.
Why Speechdub works
Reading long PDFs, research papers, or dense reports is slow and tiring, and most text-to-speech apps meter every minute of listening. Speechdub's Eco mode runs the same natural voices locally in the browser at no credit cost, so everyday desktop listening stays unlimited and free. The document chat layer adds a second pass over the same content, letting listeners ask clarifying questions mid-playback rather than switching to a separate tool.
