VODER: A Speech Synthesizer from 1939 #MusicMonday
This video from VintageCG shows the workings of the VODER, a speech synthesizer demonstrated at the 1939 New York World’s Fair. Here’s more on the VODER from What Is the Voder:
An operator would select one of two basic sounds by using the wrist bar: a buzz tone and a hissing sound. The buzz tone was the building block for vowel sounds and nasal type sounds. The hissing sound was the building block for those sounds associated with consonants.
These sounds were then passed through a bank of filters that were selected by the user by selecting the appropriate keys on the keyboard. These sounds were combined and sent through a loudspeaker. For sounds not replicable by the buzzing or hissing noises, such as “p”, “d”, “j”, and “ch”, additional filters were selectable
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
