Visit SpeechifyWhat is Speechify?
Speechify was founded in 2017 by Cliff Weitzman, who built an early version of the tool to help himself cope with dyslexia while studying at Brown University. The concept was simple: if he could listen to his textbooks and academic papers rather than reading them, he could consume the same content faster and with less cognitive strain. That personal need became a product used by millions — Speechify has grown into the most popular AI text-to-speech productivity app available, with backing from top Silicon Valley investors and celebrity endorsements from athletes and executives.
The core product converts any text content into natural-sounding AI speech. Users can import PDFs, Microsoft Word documents, PowerPoint files, Google Docs, ePub eBooks, and web articles. The Chrome extension makes any website or web-based document readable — you highlight text or simply click the Speechify button on a webpage and it begins reading aloud. On mobile, you can share content from any app directly to Speechify, or use the camera scanner to photograph physical book pages and have them read aloud. The sync feature means your reading position carries across devices, so you can start a research paper on your desktop during work and continue listening on your phone during your commute.
The speed-reading component is what makes Speechify distinctively different from standard text-to-speech tools. While most TTS engines are designed for accessibility at normal speaking speeds, Speechify is designed as a productivity tool: it trains users to listen at progressively higher speeds. The Premium plan unlocks listening up to 4.5x normal speed — approximately 900 words per minute. Users typically start at 1.5x and increase over several days as their brain adapts. Regular users often report comfortable listening at 2x to 3x speed, effectively doubling or tripling their content consumption rate.
The voice quality is a major differentiator. Speechify offers 30+ AI-generated voices that sound significantly more natural than traditional text-to-speech engines. The Premium plan includes celebrity voices (licensed from public figures) and high-definition AI voices across multiple languages and accents. Speechify AI Studio, the enterprise tier, extends this with custom voice cloning — organizations can create a branded AI voice from their own voice talent for consistent narration across all their content.

Alternatives to Speechify
If Speechify's price or feature set does not fit your needs, these alternatives cover text-to-speech and AI audio from different angles.
ElevenLabs
Professional AI voice generation platform. Better for creating high-quality voiceovers for content — not a reading tool, but excellent TTS for production use.
Murf AI
AI voiceover studio for creating professional narration for videos and presentations. Production-focused TTS rather than personal reading productivity.
Natural Reader
Free and affordable text-to-speech tool for reading documents aloud. Simpler than Speechify with fewer AI voice options but a lower price point.
Google Read Aloud
Free built-in text-to-speech in Chrome and Google Docs. No cost, limited voices and speed options — suitable for occasional use without a subscription.
Frequently Asked Questions
What is Speechify?
Speechify is an AI text-to-speech productivity application founded in 2017 by Cliff Weitzman, who built the original version to manage his own dyslexia. It converts PDFs, Word documents, Google Docs, ePubs, emails, web articles, and physical book pages (via camera scan) into natural-sounding audio, playable at speeds from 0.5x to 4.5x. It runs on iOS, Android, Mac, and Chrome, with cross-device sync. It is used by millions of students, lawyers, executives, researchers, and people with reading differences who need to process large volumes of written content efficiently.
How fast can Speechify read?
Speechify Premium supports playback speeds from 0.5x up to 4.5x normal speaking speed — approximately 900 words per minute at maximum. The free plan limits speed to 1x. The company recommends a gradual approach: start at 1.5x and increase the speed by 0.25x every few days as your brain adapts to the faster audio processing rate. Most dedicated users find themselves comfortably listening at 2x to 3x speed within a week or two of regular use. At 2x speed, you can effectively read twice as many pages of content in the same time.
What types of content can Speechify read?
Speechify can read virtually any text-based content. Supported formats include PDF files, Microsoft Word and PowerPoint documents, Google Docs and Slides, ePub eBooks, email messages (via iOS Mail integration), web articles and pages (via Chrome extension or iOS share sheet), and physical printed text captured via the mobile camera scanner. If text is visible on your screen or in a file, Speechify can almost certainly read it. The Chrome extension is particularly powerful, enabling you to listen to any website, web article, or web-based PDF without needing to download it first.
Is Speechify worth the $139/year price?
Whether Speechify Premium justifies its $139/year cost depends on how intensively you read written content. For students who read dozens of papers per week, lawyers reviewing contracts, executives consuming research reports, or researchers processing literature, the time savings at 2x or 3x speed can easily save multiple hours per week. For these users, the ROI is clear. For occasional readers who process documents a few times per week, the free tier or browser-native read-aloud features may be sufficient. Speechify offers a 3-day free trial of Premium so you can evaluate whether the speed and voice quality justify the cost before committing.
How does Speechify compare to ElevenLabs?
Speechify and ElevenLabs address fundamentally different needs. Speechify is a personal productivity tool for consuming written content faster — it is about listening to documents you need to read, not creating audio for others. ElevenLabs is a professional AI voice generation platform for creating high-quality voiceovers, audiobooks, video narration, and synthetic speech for content production. If you want to read your own documents faster, choose Speechify. If you want to generate professional AI voices for content you are publishing or producing, ElevenLabs is the stronger choice. Speechify's enterprise AI Studio does offer voice cloning for production use, but that is a different product tier from the personal reading app.
Does Speechify work offline?
Yes. The iOS and Android apps support offline listening on the Premium plan. You can download specific documents, PDFs, or books to your device while connected to the internet, then listen to them without a data connection. Reading position syncs to the cloud when you reconnect. Offline support is available for downloaded content only — you cannot import new documents while offline. The Chrome extension and web app require an internet connection. Offline playback is particularly useful for commuters, frequent travelers, and gym-goers who want to listen to content without using mobile data.
