A Method for Studying Speech Communication Systems
Edith L. R. Corliss · The Journal of the Acoustical Society of America · 1952
Because of the statistical nature of speech sounds, time-exposure photographs of the display on a Panoramic Analyzer can be used as high speed acoustic spectrograms of impulsive sounds. For speech systems, the analyzer is modified to sweep at the syllable articulation rate. The photographs can be interpreted to show quantitatively a number of characteristics of speech communication systems. So far, this process has been applied to the study of the characteristics of speech recordings and in the calibration of speech audiometers.
