Microsoft Speech Recognizer 6.1 Training Files

Question

I am developing a Speech Application in C#. The speech recognition stuff is working fine with SAPI 5.1 on Windows XP. But I now have Microsoft Speech Recognizer v 6.1 on my machine that came with Office 2003. No matter how much training I do, I see that the speech files (the .dat files under MSASR) are not getting updated ( at least from the last modified time stamp) . Can someone please let me know if there is any major change in how speech training works in Speech Recognizer v 6.1 when compared to v 5.1 ?

Thanks in advance.

UPDATE: Someone answered the question in the Microsoft Speech Forums. Here is the link to the reply. http://www.microsoft.com/communities/newsgroups/en-us/default.aspx?dg=microsoft.public.speech_tech.sdk&mid=53f6b970-3252-4ef5-91da-eaf20367c023&sloc=en-us

Answer 1

Are you sure you are looking in the right place? Check the registry under HKEY_CURRENT_USER\Software\Microsoft\Speech\RecoProfiles for info about user profiles and training data. I'm on Vista, control panel indicates that it is version 8.0. I see the training files updating.

This MSDN reference has details of registry settings http://msdn.microsoft.com/en-us/library/ms717036(VS.85).aspx

Answer 2

Thanks for your reply. I am actually looking at the files under HKEY_CURRENT_USER\Software\Microsoft\Speech\RecoProfiles\Tokens\{UUID}{EngineCLSID}\Files. The file update process seems to be extremely random and the file count is different on different PC's.(File Count: 4 on my PC vs 3 on my colleagues PC). I was just wondering if there is any change in the location of the files that get updated in XP with 6.1 Recognizer.
