![]() This fundamental frequency is typically known as f0. Expressive speech depends a lot on correct modulation of pitch. The overall pitch or fundamental frequency of speech comes from oscillations of the vocal cords: the buzzer in this model. The ratio on f1 to f2 define the sound of various vowels. The mouth formant ( f1) and throat format ( f2) are critical to creating sounds that are recognizable as speech. The human vocal tract has lots of potential for complicated resonances in the mouth, throat, nasal cavities etc. These resonance frequencies are known as formants. I would love to see someone recreate this and learn how to play it. By varying the capacitance, resistance and inductance of the circuit he could produce a series of vowel-like sounds probably the very first example of circuit bending. His circuit consisted of a buzzer to simulate the vocal cords and a pair of oscillators to simulate the resonance of the mouth and throat. It was capable of saying such interesting things as mama, anna, wow-wow, and yi-yi. While mechanical speech synthesis dates back to the 18th century, the first successful attempt based on electronics was ‘An Electrical Analogue of the Vocal Organs’ by John Q.
