For more detail, c.f. the article: "Ciarcia's Circuit Cellar: The
Lis'ner 1000" by Steve Ciarcia in Byte, Nov., 1984.

The following is a description quoted from this article:

"The SP1000 is a 5-volt 28-pin NMOS microprocessor peripheral
chip that can be used for both speech recognition and LPC speech synthesis.
Using a bidirectional data bus and control lines, the SP1000 interfaces
to most 8-bit processors as a memory mapped peripheral device.
The unique aspect of the SP1000 is its ability to do LPC analysis in real
time........"
