WSR is a locally processed speech recognition platform; it does not rely on [[cloud computing]] for accuracy, dictation, or recognition, but adapts based on contexts, grammars, speech samples, training sessions, and vocabularies. It provides a personal dictionary that allows users to include or exclude words or expressions from dictation and to record pronunciations to increase recognition accuracy. Custom language models are also supported.

With Windows Vista, WSR was developed to be integratedpart intoof Windows, as speech recognition was previously exclusive to applications such as [[Windows Media Player]]. It is present in [[Windows 7]], [[Windows 8]], [[Windows 8.1]], [[Windows RT]], and [[Windows 10]].

==History==

Microsoft was involved in speech recognition and [[speech synthesis]] research for many years before WSR. In 1993, Microsoft hired [[Xuedong Huang]] from [[Carnegie Mellon University]] to lead its speech development efforts; the company's research led to the development of the [[Speech Application Programming Interface|Speech API]] introduced in 1994.<ref name="TalkingWindowsVista">{{cite web |url=http://msdn2.microsoft.com/en-us/magazine/cc163663.aspx |title=Exploring New Speech Recognition And Synthesis APIs In Windows Vista |last=Brown |first=Robert |publisher=[[Microsoft]] |work=MSDN Magazine |archiveurl=https://web.archive.org/web/20080307054756/http://msdn2.microsoft.com/en-us/magazine/cc163663.aspx |archivedate=March 7, 2008 |accessdate=June 26, 2015}}</ref> Speech recognition had also been used in previous Microsoft products.
