Tissyo Voice · Listen differently
Convert any document to listen
Tissyo Voice converts any PDF, web article, or scanned document into natural-sounding audio. Listen to anything, anywhere — without an internet connection.
What is a Voice Synthesis App?
A voice synthesis app (TTS) reads text aloud using AI-generated voices. Tissyo Voice goes further — it transforms entire documents, web pages, and scanned books into immersive audio you can listen to hands-free.
PDF to Audio
Import any PDF — books, research articles, reports — and let Tissyo Voice read it with natural intonation. No copying and pasting required.
Websites to Audio
Share any article from Safari to Tissyo Voice. The app removes ads and noise, then converts the text to voice instantly.
Scanned Documents (OCR)
Scan physical books or printed pages. The integrated OCR extracts the text, then AI voices read it aloud — from paper to audio without effort.
Notebooks & DOCX
Paste text from your notebook or import DOCX files. Any text becomes high-quality audio in a few seconds.
100% Offline & Private
All AI vocal processing is done on the device. Vocal processing is done entirely on your device. No third-party cloud, no tracking, no data collection. Synchronisation via iCloud.
Accelerated Listening up to 3x
Listen up to 3x the normal speed without distortion. Combined with word-by-word tracking (karaoke mode), you retain more information faster.
