Andrew Neural: Free TTS from Microsoft Edge

Andrew Neural is a text-to-speech voice from Microsoft. It is served through their neural speech model, and the edge-tts Python library exposes it for free — the same voices Microsoft Edge uses for its built-in "Read Aloud" feature. No API key, no account, no subscription.

I use Andrew Neural as my default TTS voice across everything: AI assistant responses, automation scripts, daily briefings. Anything that needs to speak out loud goes through it.

How to use it

Install the library:

pip install edge-tts

Then speak something:

edge-tts --voice en-US-AndrewNeural --text "Hello world" --write-media hello.mp3 && afplay hello.mp3

That is the whole trick. Swap the voice name to try others like en-US-JennyNeural, en-GB-SoniaNeural, or en-AU-NatashaNeural. There are over 400 voices across 140 languages.
