An analysis of the features of the audio signal is considered to be an important part in identifying the types of coughing in dogs. By using a key feature analysis method based on spectrum (Spectral Feature Based) over the estimated coefficient linear bond techniques (Linear prediction coding: LPC) which is a popular technique used to analyse the physical properties of an audio signal in animals and are used to separate the audio output of the redundant by lpc command to use and apply the results from wave conversion process used in the calculation of the pallet, the result is the estimated coefficient linear bond that resembles a metric, which is used in the classification process, the information in the following sequence.
