No, that was the Sonovox.
The Sonovox applied a vibrator to the throat in order to excite the vocal cords without the use of the lungs. Speech or singing was done by using the mouth, teeth, and tongue as usual. It goes back to Alvino Rey, who was also a ham radio operator, you can find videos of it with his wife who was one of the King Sisters.
Bob’s talk-box was actually invented by Pete Drake, who was a studio musician at RCA’s famed Nashville studio B. Hie played his “talking steel guitar” into a speaker that conducted sound into the mouth via a tube. Bob Heil improved on it and made it louder for use with rock music.
PAMS of Dallas created many jingles using the Sonvox and even recorded a long piece of instrumental music for use as a bed named the “Sonowaltz”.
