Many Mac (s aapl) users, especially bloggers like me who suffer from repetitive injury syndrome, have become fans of MacSpeech Dictate, a dictation software made by the Salem, N.H.-based company MacSpeech. The company used Nuance Communications’ (s NUAN) core technology to offer this service. Today, Nuance, which owns Dragon NaturallySpeaking software, said it’s buying MacSpeech for an undisclosed amount. With sales of Apple’s computers on an upswing, it makes sense for Nuance to add the top speech recognition product to its portfolio. I, for one, am happy to see that MacSpeech is going to be around for awhile.
