3.5.2 analysis features (Feature Extraction)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.ช้ใน redundant fragments of sound output by lpc command to use and apply the results from wave pallet, the conversion process used in the calculation and analysis of audio signal to pass through in order to find the predicted coefficient is compared with the actual signal. Error value to bring it to him along with the encoding process the batch analysis of the coefficient and then encoding to export to. The result is the estimated coefficient linear bond series has a metric, which is used in the classification process, the information in the following sequence.
