EUROSPEECH 2001 Scandinavia
The presented research evaluates the quantitative characterization of human cough sounds by estimating the fundamental frequency or pitch. The fundamental frequency was determined by autocorrelation analysis on both the rough time-signal and the linear predicted time-signal. Differences between `spontaneous' and `voluntary' cough sounds are put forward. The experimental cough database was registered in the free acoustical field on respectively 3 pathological and 9 healthy nonsmoking subjects.
