Speechify

Speechify is the leading text-to-speech app for consuming written content faster. Used by over 20 million people — particularly those with dyslexia, ADHD, or simply high reading demands — it converts any text into natural-sounding audio you can listen to at up to 4.5x speed.

The free tier gives access to standard voices and up to 1x speed. Premium ($11.58/mo billed annually) unlocks AI voices, speeds up to 4.5x, and all file types. The AI voice quality has improved dramatically — premium voices are nearly indistinguishable from human speech.

Speechify works across web articles, PDFs, Google Docs, emails, textbooks, and ebooks. The browser extension captures any webpage; the mobile app scans physical documents with your camera. Over 30 languages are supported. The AI Voice Studio lets you create custom voices for podcasting and content creation.

A 2024 study found users who listen at 2–3x speed retain information as well as reading, while consuming content 2–3x faster — making Speechify a genuine productivity multiplier for high-information workers.

Pros: Dramatically speeds up content consumption, excellent AI voice quality, works on all content types, accessibility benefits, good mobile app.
Cons: Premium required for best voices and speeds, some users find high-speed listening takes time to adjust to.

Best for: Students, researchers, professionals with high reading loads, people with dyslexia or ADHD, and anyone who commutes or exercises and wants to use that time productively.
