HI, anybody have information or datasheet of the very old chip "SP1000" voice sinthetizer make by General Instruments (actualy Michochip)?
Like I said, I have the article but no scanner. What are you looking for?
So, to summarize, a sample circuit would be a good start for me. Ideally, I'd have a sample circuit for the voice recognition hookup...
Okay, here you go, I drew it up for you. The microphone low pass filter cuts out everything below 250Hz; the AGC monitors and adjusts the incoming signal amplitude so it always stays within the range of the ADC (it can adjust the gain from 0 to 42dB, in 6dB steps); the antialiasing filter cuts out all the high frequency clickity-clack from the analog switches; and the ADC converts the resulting audio to an 8bit serial data stream. The remaining logic inputs are for you to decide how best to address (from a micro or equiv.), and software, well, that's altogether something else! I don't know where you're going to find that.
Also, regarding speech synthesis, the Lis'Ner 1000 used an SSI-263 phonetic speech chip in conjunction with the circuit below. I have not added it as it requires that particular chip:
I had a dude on this forum help me with an ancient datasheet, so I thought I could reciprocate here. If you have access to the Byte Magazine archives, you'll find an article by Steve Ciarcia (Circuit Cellar) in the NOV84 issue that uses the SP1000, called "The Lis'Ner 1000." I have the article here in front of me but no way to scan it...
What precisely are you looking for?
Hi, I'd like to attach this device to an FPGA design I have for a robotics project. Can you tell me if the Byte article covers any of the information that I can use to do this? Like SP-1000 registers and timing information? Or does the article just direct you to the datasheets?
