A Web server running Microsoft Internet Information Services (IIS) 6.x or later is an integral part of a complete Speech Server deployment.
IIS is included with Windows Server 2003, Windows??XP Professional SP2, and Windows Vista. However, you must explicitly install IIS the first time it is used with Speech Server. For IIS installation instructions, see Speech Server Requirements.
The Web server hosts Web-based voice response applications, including application resources such as prompt databases and grammar files. It generates the application Web pages that contain VoiceXML, HTML, SALT, and scripts. A VoiceXML interpreter and a SALT interpreter, installed with Speech Server, connect to the Web server. For more information about the Speech Server architecture, see Architecture Diagram: Runtime and Operations.
The Web server hosts ASP.NET pages (.aspx) for applications developed using Speech Server Developer Tools or ASP.NET Speech Controls.
