ASR (Automatic Speech Recognition) is the transformation of spoken content into its textual representation. Or simply said: Speech-to-Text.

Speech Recognition can be done via a computer program on your own computer (Windows, Linux, OSX) or via a webservice. The advantage of software on your own computer is that you are completely in control. Especially when you have (very) sensitive data that may not leave the building, it make sense to run the ASR on your own computer.
