Text to Speech: Convert Text to Natural Speech in Your Browser

What Is Text to Speech?

Text to speech (TTS) converts written text into spoken audio using a synthesized voice. Instead of recording a human voice, a TTS engine analyzes the text and generates speech in real time — which is why the same sentence can be read instantly in dozens of different voices and languages.

This tool uses your browser's own built-in speech engine (the Web Speech API) rather than a cloud AI service. That's a deliberate choice: it means the conversion happens on your device, your text never leaves your browser, and there's no server round-trip slowing things down. The trade-off is that voice selection depends on what's installed on your operating system rather than a proprietary voice library — we'll walk through exactly what that means below.

Follow Along With Live Word Highlighting

As the voice reads, the word currently being spoken highlights on screen in real time. We built this specifically for two situations we kept running into ourselves: proofreading a draft where hearing and seeing the exact word catches mistakes silent reading misses, and reading along with content for anyone who processes text better when it's paired with audio, including many people with dyslexia.

One honest limitation: if you're using the Pronunciation Dictionary below to change how a word sounds, highlighting turns off for that playback. The spoken audio and the visible text are no longer word-for-word identical at that point, so we'd rather disable the highlight than show you a position that's slightly off.

Browser Compatibility

Because this tool relies on the Web Speech API rather than a server, compatibility depends on your browser and operating system:

Which Voice and Settings for Which Use Case

There is no single "best" voice — the right choice depends on what you're doing. These are the combinations that work best for the most common use cases:

Fix How Any Word Is Pronounced

Browser voices are generally reliable, but they stumble on brand names, acronyms, and less common words — "EveryKits" itself is a good example most engines misread on the first try. The Pronunciation Dictionary lets you define exactly how a word should sound when it's spoken, without touching the text you see or copy. Add a pair once — the word as written, and how you want it pronounced — and it applies automatically every time you hit play. This works the same way for Hindi and Urdu text as it does for English.

Upload a File — or Combine Both

Prefer typing? Just use the box above. Have a longer draft saved elsewhere? Upload a .txt file and it adds to whatever you've already typed, so you can mix a quick note with pasted or uploaded content in the same read. Everything stays editable — upload doesn't lock the text box, and you can drag a file directly onto it too.

Hindi and Urdu Voice Support

This tool can read Hindi and Urdu text using whichever voices your device already has installed — we don't maintain a separate voice library, so there's nothing extra to download from us. In practice, availability depends on your operating system: Android devices (through Google's text-to-speech engine) almost always include both Hindi and Urdu voices by default. Windows and iOS support for Hindi is fairly common; Urdu support on those platforms is more inconsistent and depends on your device's installed language packs.

The Voice dropdown above tells you exactly how many Hindi and Urdu voices are available on your specific device right now. If you type or paste Urdu or Hindi text while an incompatible voice is selected, the tool detects the mismatch and offers a one-click switch to a matching voice, if one exists on your device. If the count is zero, that's a device setting rather than a limitation of this tool — on Android, go to Settings → System → Languages → Text-to-speech output to check or download additional language voices for free.

Your Text Never Leaves Your Device

Most online text-to-speech tools send whatever you type to a cloud server to generate the audio — which means your text is transmitted, and in many cases logged, somewhere outside your control before you hear a single word. This tool works differently by design: because it runs on the Web Speech API built directly into your browser, the entire conversion — reading the text, selecting the voice, generating the audio — happens locally on your device. Nothing is uploaded, there's no account required to create, and no server ever sees what you typed.

The one thing this tool does store is your last piece of text, saved only in your own browser's local storage, purely so you don't lose your place if you close the tab. That's optional convenience, not a requirement — discarding it takes one click.
