Speechify converts any text into audio you can listen to — PDFs, web articles, Google Docs, emails, ebooks, anything. It reads content to you at up to 4.5x speed, so you can consume written material faster while doing other things. Built originally as an accessibility tool for dyslexia.
Speechify reads text aloud to you. Import a PDF, paste an article, open a web page — it reads it back in a natural AI voice at whatever speed you set. The selling point is speed: with practice, most users can comfortably listen at 2x to 3x reading speed, consuming the same content in half to a third of the time.
Students — lecture notes, research papers, and textbooks while commuting. Professionals with high reading loads — reports, briefings, and emails faster. People with dyslexia — Speechify was built as an accessibility tool; text highlighting synchronised with audio is particularly effective. Language learners — hearing text read correctly while reading it simultaneously.
Research on speed listening: A 2020 Psychological Science study found intelligibility degrades above approximately 2.5x for most listeners on complex content. Speechify's recommendation: start at 1.5x and increase gradually over several weeks.
First decision: voice selection. Speechify's HD AI voices (Premium) are significantly more natural than standard OS voices. For long sessions, voice naturalness matters — robotic voices become fatiguing over an hour. Try several on a sample paragraph first.
Second decision: speed. Start lower than you think you need. 1.5x for a week, then 2x, then 2.5x if comprehension stays strong. Complex legal or technical content warrants slower speeds than narrative text.
AI Studio (highest tier) adds voice cloning, voiceover export for commercial use, and an API for programmatic TTS — moving Speechify closer to ElevenLabs and Murf territory for teams that need both a reading tool and basic voice generation.
Speechify was founded to address dyslexia. Features: synchronised word highlighting (each word highlighted as spoken), adjustable font size and background colour, and OpenDyslexic font support. One of the recommended tools for workplace accessibility accommodations for reading difficulties.
The Lende & Buchwald (2020) study in Psychological Science found intelligibility begins to degrade above approximately 2.5x for most listeners on complex content, more quickly for non-native speakers. Optimal speed is individual and content-dependent. Speechify's gradual increase approach aligns with the research on skill acquisition for accelerated listening.
