Voice user interface
（重定向自VUI）
A voice-user interface (VUI) makes human interaction with computers possible through a voice/speech platform in order to initiate an automated service or process.
A VUI is the interface to any speech application. Controlling a machine by simply talking to it was science fiction only a short time ago. Until recently, this area was considered to be artificial intelligence. However, with advances in technology, VUIs have become more commonplace, and people are taking advantage of the value that these hands-free, eyes-free interfaces provide in many situations.
