There were several manufacturers who made external sound boxes for PCs 
back in the late 80s to early 90s. They were pretty simple, consisting 
of an analogue to digital converter connected directly to the parallel 
printer port, with a small amplifier and a speaker. There were even 
articles in the electronics magazines on making your own. A lot of 
eductional software used them, and I even remember seeing one sold under 
the Disney name.

Looking at your picture though, there is no way that what you have is 
one of those! They would have only had two or three chips in them, not 
the 10 chips you have.

The picture which goes with the page is missing, but this description 
fits:

The DigiSpeech Plus audio adapter works with both DOS and Windows 3.1/95/
NT software on the same computer. The unit -- which combines a sound 
card, speaker and  microphone -- plugs into the back of the  PC.

Specifically designed for classrooms, DigiSpeech Plus boasts a sturdy 
shell that stands up to frequent use. The volume control, headset and 
microphone jacks are all located on the front of the unit, so no one 
fumbles behind the computer to make adjustments. Each adapter has two 1/
4" headphone jacks, allowing students to share the same machine.

Bundled software dictates any text file or typed sentences and 
pronounces words from a Dictionary Editor. Another package lets users 
play, record and edit audio files. DSP Solutions, Stony Brook, NY, (800)

It sounds like a fully functional PC sound card, but running off a 
parallel port.
