gTTS — Python library and CLI that turns text into spoken mp3 via Google Translate's speech API
Decide the text, language and output: an mp3 file, bytes for further audio processing, or stdout in a pipeline.
pip install gTTS — no credentials or project setup needed.
In code, pass the text and language to gTTS(...); optionally add pre-processors for pronunciation fixes.
Save your first mp3 with tts.save(...) or the gtts-cli command, and play it back.
Use the gTTS class in Python or the gtts-cli command for one-off conversions.
A customizable speech-specific sentence tokenizer allows unlimited text lengths while preserving intonation, abbreviations and decimals.
Customizable pre-processing hooks can, for example, provide pronunciation corrections.
Write spoken mp3 to a file, a file-like object (bytestring) for further manipulation, or stdout.
Language selection follows Google Translate's TTS voices (pass the language code to gTTS).
No API key or cloud project — it calls the public Google Translate speech endpoint (internet required).
Clone gTTS if you want the source; users install from PyPI in step 2.
git clone https://github.com/pndurette/gTTS.git
cd gTTSInstall gTTS from PyPI.
pip install gTTSUse the CLI quickstart, or the three-line Python module example.
gtts-cli 'hello' --output hello.mp3
# Python: from gtts import gTTS; gTTS('hello').save('hello.mp3')pndurette (Pierre Nicolas Durette) and contributors maintain it; documentation is at gtts.readthedocs.org.
Yes, MIT-licensed, and the endpoint it uses needs no key. The README warns it relies on an undocumented Google Translate feature, so upstream breaking changes can occur without notice.
No key at all — but it does need internet access to reach Google Translate's speech service.
pyttsx3 works fully offline with system voices; Google Cloud TTS is the official paid API with more voices and an SLA. gTTS sits in between: free and simple, but online and unofficial.
pip install gTTS, then gtts-cli 'hello' --output hello.mp3.
