Quote: Radio Rex- Speech recognition has a long and spotty history in the toy industry. Radio Rex was the first commercial toy to respond to voice commands. Produced in 1922 by the Elmwood Button Co., Radio Rex predates computers by more than 20 years. Rex is a brown bulldog made of celluloid and metal that responds to its name by leaping out of its house. The dog is controlled by a spring that is held in check by an electromagnet. The electromagnet is sensitive to sound patterns containing acoustic energy around 500 Hz, such as the vowel in "Rex." The acoustic trigger interrupts the current to the electromagnet allowing the spring to propel Rex out of its house.

I did, but only by a hand clap.
Mine was made by the John Hugo Mfg. Co. in New Haven and the label lists several patents to H.C. Berger in 1913, 1916 and 1918. There were many versions.

We had a voice operated Dancing Dan in the early 60's. (made around '57) You shouted into the mic and press the button, he would tap dance.

Maybe not so much of a voice recognition than a voice activated device.
Never seen a Radio Rex, but if I do, I will know what it is.

My brother used to have a huge food dish in his breezeway, marked "REX". It was for his cat.

My older brother, a lingustics professor, explains why Rex is so stubborn-
Quote: Hi John, That's clever, but the crudest possible voice recognition. I study sound spectrograms all the time in my phonetics course, and it is true that the first formant in the vowel [e] is at about 500 hz, but only in the adult male voice, so Rex would not respond to women or children unless they used a different vowel, like [i] or [I], or even [u] or [U]. They would have to call him "Reeks" or "Riks" or "Rooks" or "Ruks" in order to get the first formant low enough. I bet you have to say it really loud, too.
