Looking for Doos

Decades ago, when I was still using Windows, I recorded a cute little track with a MIDI vocal sound as the lead instrument.
It was a “Doo” sound like this;

Since the time I recorded it, I’ve moved to Windows and 25 years have elapsed.
I’ve lost the sound module that provided the vocals.
Everything I have now just gives me oohs and aahs.
Does anyone know where I can get my dooh back again?
