Whats the story with SAPI on Windows 2000 systems?
Windows 2000 comes with newer versions of the SAPI 4 OS extensions and MS TTS engine than whats available on the MS IIS website however, Windows 2000 has no a built in Speech Recognition engine. This information is particularly important to those writing application installers and those setting up speech on a system. If the target system is Windows 2000 do not install spchapi.exe. Or if spchapi.exe is run then the questions regarding the replacement of existent files should be answered so the existing files are left alone. This Talking Clock sample project includes code for a custom Install Shield Express DLL that demonstrates how to install SAPI and speech engines. This code checks for the existence of SAPI and speech engines before installing them so it will handle the case of a Windows 2000 target system. Back to Top Revised: October 18, 2005.
