On a side project, I'm looking at the best interface to facilitate further edition (correction) of the recognized text. Target is local councils and regional parliament, where sessions are usually recorded but without transcripts. If xx% accuracy is enough to identify keywords, manual edition is still required to not distort precise meaning.
Nothing special in the interface, but two features seems interesting: 1. Be able to collaborate in real-time. Maybe using Etherpad API to merge multiple editions. 2. Easily validate text and label speakers so as to generate new training data.
Pointers to similar existing solutions would be very appreciated.
