How Does Text to Speech Work?

This tool uses your browser's built-in Web Speech API (speechSynthesis) to convert text into spoken audio. Simply type or paste your text, select a voice from the available options, adjust speed and pitch to your liking, and click Play. The speech is generated entirely on your device -- no data is sent to any server, and it works offline. Available voices depend on your browser and operating system.

Frequently Asked Questions

Does text to speech work offline?
Yes, this tool uses your browser's built-in speech synthesis API. It works completely offline with no internet connection needed.
Why do available voices differ?
Available voices depend on your browser and operating system. Chrome on Windows typically has the most voices, while other browsers may have fewer options.
Can I adjust the speed?
Yes, use the speed slider to adjust from 0.5x (slow) to 2x (fast). The default is 1x normal speed.
Is there a text length limit?
There is no hard limit, but very long texts may be split by the browser. For best results, keep text under 5000 characters.

How browser text-to-speech works, and its limits

Browser speech synthesis uses voices installed on your device, not a cloud service — which is why the same page sounds completely different on an iPhone and on a Windows laptop, and why the available Indian-language voices depend entirely on your operating system.

Voice availability by platform

The quirks that catch every developer

Where text-to-speech genuinely helps

  1. Accessibility. Reading long content aloud for users with dyslexia, low vision or reading fatigue. Note this supplements rather than replaces a proper screen-reader experience — semantic HTML and correct headings still do the real work.
  2. Proofreading. Hearing your own writing read back is the fastest way to catch a dropped word or a clumsy sentence; the ear catches what the eye skips.
  3. Language learning. Hearing correct pronunciation of a written word, particularly useful for scripts you read slowly.
  4. Hands-free consumption — listening to an article while commuting or cooking.
  5. Pronunciation checks for names, though results are unreliable for names outside the voice’s training language.

More questions people ask

Does browser text-to-speech need an internet connection?

Usually no — it uses voices installed on your device. Chrome on desktop also offers higher-quality Google network voices, and those do require connectivity.

Why does the voice sound different on my phone and my laptop?

Because the browser uses the operating system’s own speech engine. Apple, Google, Microsoft and eSpeak all sound distinct, and the set of installed voices differs on every device.

Can browser text-to-speech read Hindi?

Yes, if a Hindi voice is installed. iOS, macOS and Android ship good Hindi voices; on Windows you generally have to install the Hindi language pack first, and on Linux the eSpeak output is intelligible but robotic.

Why does speech stop partway through a long text?

Several browsers fail silently on very long utterances. Split the text into chunks of under about 200 characters at sentence boundaries and queue them, rather than passing one large string.

Is the Web Speech API a substitute for a screen reader?

No. A screen reader navigates structure — headings, landmarks, form labels, tables — and lets the user move through it. Speech synthesis just reads text aloud. Semantic HTML remains the thing that makes a page accessible.

Everything on this page runs in your browser — nothing you type is uploaded or stored.
