In Mavericks, is it possible to use Enhanced Dictation from the command line? A use case is: I have a recording in AIFF or MP3 format, and I'd like a text version of it as Enhanced Dictation would have recognized it if I had spoken it myself.
Copy the MP3 file to an iPod &amp; play it into Dictation via line in source (or the mic?)... Not the answer to your question, but it might work for your task :)
