From The Free On-line Dictionary of Computing (18 March 2015) :

  speech recognition
  voice recognition
  
      (Or voice recognition) The identification of
     spoken words by a machine.  The spoken words are digitised
     (turned into sequence of numbers) and matched against coded
     dictionaries in order to identify the words.
  
     Most systems must be "trained," requiring samples of all the
     actual words that will be spoken by the user of the system.
     The sample words are digitised, stored in the computer and
     used to match against future words.  More sophisticated
     systems require voice samples, but not of every word.  The
     system uses the voice samples in conjunction with dictionaries
     of larger vocabularies to match the incoming words.  Yet other
     systems aim to be "speaker-independent", i.e. they will
     recognise words in their vocabulary from any speaker without
     training.
  
     Another variation is the degree with which systems can cope
     with connected speech.  People tend to run words together,
     e.g. "next week" becomes "neksweek" (the "t" is dropped).  For
     a voice recognition system to identify words in connected
     speech it must take into account the way words are modified by
     the preceding and following words.
  
     It has been said (in 1994) that computers will need to be
     something like 1000 times faster before large vocabulary (a
     few thousand words), speaker-independent, connected speech
     voice recognition will be feasible.
