I think my solution below does NOT work in Vista Business. I just installed that on my machine and had to change up the fix to get it to work.
Here is the Vista Business fix:
Installation of TrueSpeech Codec for WMP 11 – Windows Vista Professional
Option 1
The DSP codec can be installed on Vista using the following procedure:
1. Acquire tssoft32.acm and tsd32.dll (can be easily found by searching for them online)
a. I found tssoft32.acm here:
http://members.driverguide.com/driver/detail.php?driverid=7020
i. NOTE: just do the free sign-up, because the “series of ads” never ends!...use an alias
b. I found tsd32.dll here:
http://www.driverskit.com/dll/tsd32.dll/3632.html
i. NOTE: they make you wait for 100 seconds hoping you’ll click on some ads while you wait…click a couple and they’ll make some $$$
2. Copy both files to the “C:\Windows\System32” folder
a. Note: If tssoft32.acm is present, rename it tssoft32_old.acm before you copy the new version to the folder
3. Place tssoft32.acm and tsd32.dll into the Windows\System32 directory
4. Create the following registry entry:
a. Navigate to the following folder:
KEY_LOCAL_MACHINE>Software\Microsoft\Windows NT\CurrentVersion\Drivers32
b. When inside the Drivers 32 folder, right-click and select New > String Value
c. Name it “msacm.trspch”
d. Right-click the new “msacm.trspch” and click “Modify”
e. Set REG_SZ value to: “tssoft32.acm”
f. No need to reboot, just close regedit
g. The registry setting should look like this:

5. You can verify that it is installed by opening WMP 11 and under the Help menu, clicking on “About Windows Media Player” and then “Technical Support Information”. A webpage will open listing all the codecs installed. If tssoft32.acm is listed, you’re set! If not, I am sorry, but I cannot help you :-(
where to get DSP True Speech Audio CODEC?
