Today in 1978, Texas Instruments announced Speak & Spell.
A talking learning aid for ages 7 and up, it marked
the first time the human vocal tract had been electronically duplicated on a single chip of silicon with signal processing applications… The speak and Spell digital signal processing (DSP) innovation in audio processing is the starting milestone for the huge digital signal processing industry…
Digital signal processing has become the most significant innovation that includes integrated circuits and systems design and signal processing algorithms and applications. This has been influencing human kind from the initial audio and speech processing to video and graphics processing, to machine control and automation, and to communications and image processing. Modern wireless communications is the best embodiment of digital signal processing technology that made clear audio, clear video transmissions a reality.
Digital signal processing has connected the analog world with the digital world much tighter and closer for the world we live in.
Also today, on June 11, 1949, The London Times quoted the mathematician Alan Turing: “I do not see why it (the machine) should not enter any one of the fields normally covered by the human intellect, and eventually compete on equal terms. I do not think you even draw the line about sonnets, though the comparison is perhaps a little bit unfair because a sonnet written by a machine will be better appreciated by another machine.”
