Most people think of voice biometrics as a relatively new technology. However, according to a 2004 article by Lisa Myers (SANS Institute), the history of voice biometrics actually began in 1867. At that time, Alexander Graham Bell’s father began work on developing an early voiceprint. Jumping ahead to World War 2, the same article mentions the pioneering work by Bell Telephone Labs on spectrograms. The concept was to identify a specific enemy’s voice and track their movements by the location of their radio transmissions. Apparently, the technology did not work very well.
Fast forward two decades. According to the National Science and Technology Council, in 1960, a Swedish professor, Gunnar Fant, published a ground-breaking model describing the physiological components of acoustic speech production. Fant’s model was expanded in 1970, by Dr. Joseph Perkell, to include the tongue and jaw. In 1976, Texas Instruments developed a prototype voice biometrics system that was tested by the United States Air Force and Mitre Corporation. Voice biometrics was on its way!
