## What is Speech Flow?

SpeechFlow turns documents into something you can listen to, skim, and ask about — on your iPhone.

IMPORT ALMOST ANYTHING
• PDFs, photos of pages, camera scans, and files from Files
• SpeechFlow extracts the text so you can work with it, not just look at it

LISTEN
• Hear the whole document read aloud
• Use built-in system voices anytime — no account required
• Clone your own voice from a 5–10 second recording and listen in that voice
• Scrub the timeline and change speed from 0.25× to 2× while it plays

SUMMARIZE & ASK
• Key points, a short paragraph, or a TL;DR
• Ask questions about the document you have open
• Summaries and answers run on the device with SpeechFlow AI engine or Apple Intelligence — your text stays on the phone

YOUR LIBRARY
• Keep documents in one place
• Jump back in and keep reading, listening, or asking

Privacy-minded by design: summaries and questions are generated on the iPhone. Cloned and preset voices use SpeechFlow’s speech service when you choose them. Only clone a voice you have the right to use.

SpeechFlow is built for people who would rather hear a report, a paper, or a long PDF than stare at it.
