An async Python library to automate solving ReCAPTCHA v2 by audio using Mozilla's DeepSpeech, PocketSphinx, Microsoft Azure’s, and Amazon's Transcribe Speech-to-Text API. Built with Pyppeteer for Chrome automation framework and similarities to Puppeteer, PyDub for easily converting MP3 files into WAV, aiohttp for async minimalistic web-server, and Python’s built-in AsyncIO for convenience.

This script was first featured on Reddit at /r/Python - see here for the thread. I’ve finally decided to release the script.


Check out 1-minute presentation of the script in action, with only 8 threads!

Linux, macOS, and Windows!


Python 3.6.0 - 3.7.0, FFmpeg, a Microsoft Azure account for Bing Speech API access, an Amazon Web Services account for Transcribe and S3 access, and for Pocketsphinx you'll need pulseaudio, swig, libasound2-dev, and libpulse-dev under Ubuntu.


$ pip install nonocaptcha


Please edit nonocaptcha.example.yaml and save as nonocaptcha.yaml

The use of proxies are required for my continuous updates and fixes on nonoCAPTCHA. Any donations would be a great help in allowing me to purchase these proxies, that are clearly expensive. If anyone is willing to share their proxies, I wouldn't hesitate to accept the offer.
