Windows

Windows built-in speech recognition

The Windows Speech Recognition version 8.0 by Microsoft comes built into Windows Vista, Windows 7 and Windows 8. Speech Recognition is available only in English, French, Spanish, German, Japanese, Simplified Chinese, and Traditional Chinese and only in the corresponding version of Windows; meaning you cannot use the speech recognition engine in one language if you use a version of Windows in another language. 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.
