Thank you, I think I understand partially, but not fully, as I'm not very well versed in speech recognition software.

Basically, my question (and I assume many other users') is "I run <Linux/Windows/Mac OS>, what are my options and how good will my recognition be with each?". Your answer above helps, but it doesn't entirely satisfy me, as I'm not sure if a model is the recognition engine, or if the engine uses the model, or how I can use it, etc.
