What Text to Speech Generator does, with a checked example

Paste text into this page, pick a voice and a speed, and the words come out of your speakers as synthesized speech. The audio is produced by the browser's built-in speech synthesis using voices installed on your operating system, so there is no account, no upload, and no waiting for a server. The surprise for most people is the voice list itself: it is whatever your OS and browser happen to offer, not a curated studio roster, and the same text sounds different on every machine.

Worked example

A concrete input and expected output from the current implementation.

Input

The quick brown fox jumps over the lazy dog.

Expected output

The sentence is spoken aloud in the selected voice at the chosen speed, with a brief pause where the period sits. No text is returned; the result is the audio itself.

The synthesizer speaks the words exactly as typed, so the output is the input's audible form: same words, same order. The period is not spoken itself, though engines usually pause briefly at a sentence boundary.

How the result is produced

Where the voices come from

The voice dropdown is populated from the speech engines the browser discovers on your device. Each entry pairs a language with a persona, so one entry might read American English and another might read Japanese. The selection is applied to the whole text when you trigger playback, and a different browser or operating system offers a different list.

How the speed control works

The speed control scales the voice's rate of speech around its natural default. Values below 1 slow the reading down, values above 1 speed it up, and doubling the rate cuts the reading time in half. The setting applies to the entire text at once, and playback begins immediately through the device's current audio output, so system volume is part of the result.

Good uses

Hearing how an unfamiliar name, word, or phrase is pronounced, especially in another language: pick a voice for that language and listen.
Proofreading by ear: paste a drafted email, announcement, or article and listen for typos and awkward rhythm that silent reading skips.
Previewing a narration script or voice-over before recording, to check its timing and length without opening a separate audio tool.

Limits and checks

Voices vary by device and browser. The same text with the same settings sounds different on another computer, because the voice list comes from the operating system and browser, not from this page.
You hear a live rendering, not a stored file. Browser synthesis does not produce an MP3 on its own; if this page has no download control, the audio exists only while the page plays it.
The engine reads what you typed, literally. Numbers, abbreviations, and unusual spellings are interpreted by the voice, so 'St.' or 'Dr.' may be expanded or read oddly depending on the engine, and a typo is spoken exactly as written.

Common questions

Can I download the result as an MP3?

Only if the page offers an export or download control. The browser's speech synthesis speaks through your speakers in real time and does not create an audio file by itself. If you need a file for a video or podcast, look for a download button on the page, or record the playback.

Why does it read in the wrong accent or language?

The selected voice determines the language and accent, and the tool can only list voices the operating system has installed. If no voice for your language appears, add one in the system's speech settings (System Settings on macOS, Time and Language on Windows) and reload the page.
