Windows

Windows built-in speech recognition

The Windows Speech Recognition by Microsoft is the speech recognition system that comes built into Windows Vista, Windows 7, and Windows 8. Windows Vista, Windows 7, and Windows 8 include version 8.0 of the Microsoft speech recognition engine. Speech Recognition is available only in English, French, Spanish, German, Japanese, Simplified Chinese, and Traditional Chinese and only in the corresponding version of Windows. That means that you can not use the French speech recognition engine if you use an English version of Windows. Windows 7 Ultimate and Windows 8 Pro allow you to change the system language, and therefore change which speech engine is available. Windows Speech Recognition evolved into Cortana (software) a personal assistant found in Windows 10.
