// como funciona

Como funciona

  1. Clarify your goal

    Pick your language and voice, and decide your route: a packaged install for your OS, or building from source to embed the library.

  2. Get the project

    Clone espeak-ng/espeak-ng from GitHub (or use the install path in the run steps below) and skim its README for the parts relevant to your goal.

  3. Install and configure

    Install eSpeak NG from your platform's package manager or releases, or clone and build the C source following the project documentation.

  4. Run your first task

    Synthesise one sentence to a WAV file in your language, listen to it, then adjust voice characteristics to taste.

// recursos

Por que as pessoas gostam tanto

100+ languages and accents

Supports more than a hundred languages and accents, many unavailable in heavier neural TTS systems.

Tiny footprint

The program and its data, including many languages, total only a few megabytes — practical for embedded and offline use.

WAV, SSML and HTML

Produces speech output as WAV files and accepts SSML (partially) and HTML input, not just plain text.

Adjustable voices

Includes different voices whose characteristics can be altered to change how the speech sounds.

Phoneme front end

Can translate text into phoneme codes with pitch and length, so it can front other synthesis engines such as MBROLA voices.

Written in C, everywhere

A portable C codebase used across desktop, mobile (including Android) and embedded contexts.

Execute você mesmo

  1. Clone the repository

    Get the source from the official GitHub repository for espeak-ng.

    git clone https://github.com/espeak-ng/espeak-ng.git
    cd espeak-ng
  2. Get eSpeak NG

    Install the packaged build for your operating system, or clone the repository to build from source per the documentation.

    git clone https://github.com/espeak-ng/espeak-ng.git
    cd espeak-ng  # then build per the project docs — see README
  3. Synthesise speech

    Run the synthesizer on a sentence and write it to a WAV file to verify your language and voice.

    espeak-ng "Hello world" -w out.wav  # command style per project documentation — see README

Perguntas frequentes

Who maintains espeak-ng?

The espeak-ng community project, through the espeak-ng/espeak-ng repository.

Is espeak-ng free to use?

Yes — the project is open source under the GPL-3.0 license as recorded for this listing. See the license terms for any conditions on redistribution.

Does espeak-ng need a paid API key?

No keys or network are needed — synthesis is fully local and free under GPL-3.0; note the GPL terms if you redistribute it inside a product.

How does eSpeak NG compare to a neural TTS model like VITS?

Neural models sound far more natural but need models, data and compute per language. eSpeak NG sounds robotic by comparison, yet covers 100+ languages in a few megabytes, runs anywhere, and works fully offline — reach for it for coverage and footprint, not studio quality.

How do I get started with espeak-ng?

Clone the repository (or use the documented installer), follow the install and configure steps on this page, and run the smallest real task first — synthesise one sentence to a WAV file in your language, listen to it, then adjust voice characteristics to taste.
