ClassTranscribe provides accessible, searchable lecture videos with captions using automated Speech-to-text and crowdsourcing techniques

ClassTranscribe is an open-source, web-based platform that leverages crowdsourcing to address the problem of accurate, reliable and fast transcriptions of college lectures. Completed transcriptions provide search functionality that augments existing lecture recordings and enable enhanced educational features including closed captioning.
