The study of acoustic phonetics was greatly enhanced in the late 19th century by the invention of the Edison Phonograph . The phonograph allowed the speech signal to be recorded and then later processed and analyzed. By replaying the same speech signal from the phonograph several times, filtering it each time with a different Band-pass Filter , a Spectrogram of the speech utterance could be built up. A series of papers by Ludimar Hermann published in Pflüger's Archiv in the last two decades of the 19th century investigated the spectral properties of vowels and consonants using the Edison phonograph, and it was in these papers that the term '' Formant '' was first introduced. Hermann also played back vowel recordings made with the Edison phonograph at different speeds in an effort to distinguish between Willis' and Wheatstone's theories of vowel production.

Further advances in acoustic phonetics were made possible by the development of the Telephone industry. (Incidentally, Alexander Graham Bell 's father, Alexander Melville Bell , was a phonetician.) During World War II , work at the Bell Telephone Laboratories (which invented the Spectrograph ) greatly facilitated the systematic study of the spectral properties of Periodic and aperiodic speech sounds, vocal tract Resonances and vowel Formant s, Voice Quality , Prosody , etc.

On a theoretical level, acoustic phonetics really took off when it became clear that speech acoustic could be modeled in a way analogous to , Gunnar Fant , and Morris Halle wrote "Preliminaries to Speech Analysis", a seminal work tying acoustic phonetics and phonological theory together. This little book was followed in 1960 by Fant "Acoustic Theory of Speech Production", which has remained the major theoretical foundation for speech acoustic research in both the academy and industry. (Fant was himself very involved in the telephone industry.) Other important framers of the field include Kenneth N. Stevens , Osamu Fujimura , and Peter Ladefoged .
