Purpose
Microsoft Windows Text Services Framework (TSF) is a system service included in Windows XP and later versions of the Windows operating system. TSF provides a simple and scalable framework for the delivery of advanced text input and natural language technologies. TSF can be enabled in applications, or as a TSF text service. A TSF text service provides multilingual support and delivers text services such as keyboard processors, handwriting recognition, and speech recognition.
Where Applicable
Text Services Framework is applicable for Windows-based computers using text services and Windows XP or later versions of the operating system.
Developer Audience
Text Services Framework is designed for use by Component Object Model (COM) programmers using the C/C++ programming languages. Programmers should be familiar with text services for Windows-based computers. Knowledge of handwriting recognition, speech recognition, and programming for multilingual support is recommended.
Run-Time Requirements
Text Services Framework runs on the Microsoft Windows XP operating system. It is available as a redistributable for Windows 98, Windows Millennium Edition, Windows NT 4.0, and Windows 2000. For more information about the requirements of specific API elements, see the Requirements section in the reference documentation. To download the latest redistributable, go to Windows Server 2003 SP1 Platform SDK.
