The invention concerns a method for assigning at least one sound class to a sound signal, characterized in that it comprises the following steps: dividing the sound signal into temporal segments having a specific duration, extracting the frequency parameters of the sound signal in each of the temporal segments, by determining a series of values of the frequency spectrum in a frequency range between a minimum frequency and a maximum frequency, assembling the parameters in time windows having a specific duration greater than the duration of the temporal segments, extracting from each time window, characteristic components, and on the basis of the extracted characteristic components and using a classifier, identifying the sound class of the time windows of the sound signal. |
