Audio classification and segmentation processing method based on support vector machine

Abstract

The invention belongs to the technical field of machine learning, and discloses an audio classification and segmentation processing method based on a support vector machine. The audio automatic classification and segmentation are the important means for extracting structural information and semantic content in audio, and are the basis for understanding, analyzing and searching the audio content; the method comprises two aspects including audio classification and audio segmentation, and the classification method based on the support vector machine is adopted as the classification method; the support vector machine SVM is the main achievements of machine learning in recent years; and the SVM can solve the practical problems including small samples, nonlinearity, high dimension and the like and becomes one new hot spot for neural network research. In the segmentation method, the audio segmentation method with the bayesian information criterion is used for carrying out segmentation point confirmation. For the audio segmentation, different audio types are extracted from audio stream of audio classification, namely, the audio stream is divided according to the category of the timer shaft. The experiment proves that the audio classification algorithm based on the SVM has the good classification effect, and the smooth audio segmentation result is more accurate.

Description

technical field [0001] The invention belongs to the technical field of machine learning, and in particular relates to a processing method for audio classification and segmentation based on a support vector machine. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: Today's human society has entered the digital age. With the continuous development of computer technology, network technology, and communication technology, multimedia information such as images, videos, and audios has gradually become the main form of information media in the field of information processing. Among them, audio occupies a very important position. Audio is an important part of multimedia. Compared with images and videos, audio not only has unique characteristics, but also has a small amount of audio data and fast processing speed, which has attracted widespread attention. There are various forms of audio expression, meeting people's n...
