For those who don't know, about 3 weeks ago Unspoken was exhibiting some od behavior: sounds would sometimes, for some inexplicable reason, fail to load. As far as I can tell, this was something to do with NVDA, and seems to have fixed itself. I managed to find the error, but not the cause: Libsndfile sometimes decides that .wav files are actually raw audio files, and gets upset because no one tells it how to interpret them.
Needless to say, this was only happening in NVDA and not once outside of it. Since it's been gone for about 2 weeks now, I'm assuming it's gone permanently. If anyone sees it, let me know. The add-on will throw an exception if it happens.
For now, I'm declaring unspoken useable, but not 1.0. I've bumped the version to 0.1. You can find it here.
