Audio and Speech Analysis
Homomorphic filtering is used in the log-spectral domain to separate filter effects from excitation effects, for example in the computation of the cepstrum as a sound representation; enhancements in the log spectral domain can improve sound intelligibility, for example in hearing aids.

Famous quotes containing the words speech and/or analysis:
“What is this conversation, now secular,
A speech not mine yet speaking for me in
The heaving jelly of my tribal air?
It rises in the throat, it climbs the tongue,
It perches there for secret tutelage....”
—Allen Tate (1899–1979)
“The spider-mind acquires a faculty of memory, and, with it, a singular skill of analysis and synthesis, taking apart and putting together in different relations the meshes of its trap. Man had in the beginning no power of analysis or synthesis approaching that of the spider, or even of the honey-bee; but he had acute sensibility to the higher forces.”
—Henry Brooks Adams (1838–1918)
