I'm trying to find a trial version for WSAD 5.1.0 since I would like
to install the trial version of Voice Toolkit V5.0 with it as well.

All I can find on the ibm site is trial version for WSAD 5.1.2 which
is not compatible with the trial version of Voice Toolkit V5.0.

Any idea where I can find this trial version for WSAD 5.1.0? Please
give me links.
