Free Text to Speech & Word Counter — Everything You Need in One Place

Whether you are a student proofreading an essay, a content creator checking article length, a professional preparing a speech, or someone who simply learns better by hearing text read aloud, our free online Text to Speech and Word Counter tool was built for you. No account. No software install. No time limits. Just paste your text and go.


What This Tool Does

This all-in-one text analysis tool combines two essential utilities into a single, distraction-free workspace:

  • Text to Speech (TTS): Instantly converts any typed or pasted text into natural-sounding audio using your browser's built-in Web Speech API. Choose from over 10 languages including English (US/UK), Spanish, French, German, Italian, Portuguese, Japanese, Korean, Chinese, Arabic, Hindi, and Russian.
  • Live Word Counter: Counts words, characters, sentences, paragraphs, and characters without spaces in real time as you type — just like Google Docs or Microsoft Word.
  • Reading & Speaking Time Estimator: Instantly shows how long it will take to read or speak your text aloud, based on average reading speed (200 wpm) and average speaking pace (130 wpm).
  • Top Keyword Extractor: Automatically surfaces the most-used non-stop words in your text, helping writers spot repetition and SEO professionals check keyword density.
  • Speed Control: Slow down or speed up the TTS voice from 0.5× to 2×.
  • RTL Support: One-click toggle for right-to-left languages like Arabic, Hebrew, and Urdu.
  • Copy & Download: Copy your text to clipboard or download it as a .txt file with a single click.

Who Uses a Text to Speech Tool Online?

Students & Academic Writers

Hearing your own writing read back to you is one of the most effective proofreading techniques. Our TTS tool helps students catch awkward phrasing, missing words, and run-on sentences that the eye often skips. The word counter keeps academic submissions on target with assignment word limits.

Content Creators & Bloggers

Blog posts and articles live and die by readability. Use the reading time estimator to hit the "sweet spot" for your audience — short enough to hold attention, long enough for SEO. The keyword extractor gives an instant snapshot of keyword density without any additional SEO tool.

Professionals & Public Speakers

Preparing a presentation, pitch, or keynote? Paste your script and use the speaking time calculator to know exactly how long your speech will run at a natural pace. Adjust the TTS speed to rehearse at a comfortable tempo.

Language Learners

Hear how words are pronounced in Spanish, French, German, Japanese, and 10+ other languages. The TTS engine uses native browser voices for accurate pronunciation, making it a quick and free alternative to expensive language apps.

Accessibility & Dyslexia Support

Text to speech is a proven accessibility aid for people with dyslexia, visual impairments, or reading difficulties. Our tool requires no plug-ins and works on all devices, making accessible reading available to everyone for free.
