Vocoder history ...
The voice as spectrum.
Invention of Vocoder (1928): Dudley
In the mid-1930s, work on speech and hearing was expanded to include
analysis and synthesis techniques for speech transmission. Initial
efforts culminated in the development of a speech analyzer called
"vocoder" and an electrical speech synthesizer, named "voder," and
led to the concepts of formant coding for speech transmission over
Vocoder :In conceiving the vocoder, Dudley recognized the carrier
nature of speech. He observed that the speech signal is formed by
modulating (with the slowly changing vocal resonances) the spectral
shape of the sound produced by vocal sources. The vocal sound sources
may be periodic, as produced by vocal cord vibration, or aperiodic,
as produced by turbulent airflow at a constriction.
