I spend a LOT of my time typing comments on documents: I supervise postgraduate students. I've explored a number of speech-to-text systems. Most of them fail when you use technical language in my field and generally become unusable for anything except generic colloquial language. Mote is the best I have found so far that does a good job of transcribing that manages the technical jargon of my field. It has really improved my productivity on providing detailed notes on documents.

The main reason I recommend the mote extension is that it is very easy to use. Another reason is that quick communication with students and feedback are very valuable for education.

It has been wonderful to put in those messages to students while correcting or posting work out to them. I appreciate this uncomplicated method of reaching my students and I know that they have appreciated it as well.
