In a recent "Electronic Design" magazine,

was an article about IBM and digitized speech. It is an interesting column,
as well as Bob Pease's.
Can you summarize the article? I can imagine a lot of ways to digitize
speech without a lot of RAM, but I'm curious about what they were doing in
the 50's with the data. I seem to remember things like "formant"
decomposition and analysis to be reasearch topics in the 70's. Come to
think of it, I don't even know when things like the FFT were invented, but
I thought even that was not until the 60's or so.
