Except he said 2-pin headers, alias jumper pins.

And the SC-01-A is a phoneme speech synthesizer chip,
so this is certainly a speech synth board.

The pot is the volume or pitch control (I'd bet
pitch).
With any luch the EPROM contains a text-to-speech algorithm.
I'd try hooking up a speaker to each of the two-pin headers in turn.
One is the speaker output, and the other is for attaching the Apple speaker
output,
so that a single speaker, like the one in the Apple, can serve for both
outputs.

Then try a PR#s, where the board is in slot s, and type in something and see
what it says!  ;-)
