It's very cool. Some things I noticed: fluency scores are always None for me. If you ask their name they give a different one to the diarised name! Thirdly they come in very strong, above my level so I find it quite hard to use.
Thanks for the feedback - that's all really useful. Do you mind if I ask what language you were using when the fluency score was none? Seems that it's broken for a few languages, so will fix it asap.
