A recognition system is a computer application that can be used to recognise things like speech fingerprints and writing.
An OCR system is a normal scanner and some special software. The scanner is used to scan text on a document or piece of paper into the computer. The OCR software then examines the page and changes the letters into a form that can be edited or processed by a normal word processing package.
Speech recognition is a computer application being able to respond to speech. A car entertainment system may respond to simple commands like Radio On or Radio Off because its computer programming includes speech recognition. Speech recognition is still very challenging as a computer finds it difficult to deal with different accents speaking speeds and high background noise.
