In a forthcoming article I will be describing a DirectSound based Wave Player-Recorder, with some unusual features.

The GUI will include a simple volume control for playback. Since I wanted that control to be synchronized with the system Volume Control utility, I needed to use WinMM.DLL functions and I thought this interim article outlining how those functions are used, and showing in particular how such a control can be synchronized with the system Volume Control, might be of general interest.

Online Article: Building Speech-Enabled Applications with ASP.NET

While sleepless the other night, I was channel surfing and ran across a rerun of the 1968 science fiction classic "2001: A Space Odyssey."If you haven't seen this movie, it's definitely a must see. HAL, one of the main characters of the movie, is a slightly psychotic speech-enabled super computer. HAL is responsible for steering the Discovery spacecraft on its ill-fated Jupiter mission. As I watched the movie I was completely amazed at HAL's abilities. HAL handled press interviews, played a wicked game of chess, has varied opinions on art, controls life support, and can read lips. Not to completely destroy the movie if you haven't seen it, but I have to say that I am grateful that most of the movie's predictions aren't true. However, like the HAL of 1968, speech-enabled applications have become a core requirement for both corporate and commercial developers. In this article, I'll help you explore the Microsoft Speech Platform that comprises the Speech Application Software Development Kit (SASDK) and Microsoft Speech Server 2004. I'll also show you how you can use these technologies with Visual Studio 2003 to both build and deploy speech-enabled applications.
