Abstract

The invention relates to speech signal processing and classification technology, and is a classification method and system for poetry recitation style. The method includes: preparing the original audio of poetry recitation, obtaining the start time annotation of each word and each sentence, and obtaining the corresponding start time. Time labeling data, obtain the scoring data and style labeling data of the original audio; extract the audio feature sequence of the original audio, segment the poems and sentences, and form the audio feature sequence into a multi-channel two-dimensional array; use the two-dimensional array and scoring data as The input of the CNN neural network is trained to obtain weights; the parameters of the fully connected layer of the CNN neural network are changed, and the obtained training results are used as the style classification network; the style classification network is used to classify the recitation style of the recitation audio of ancient poems. The invention can quickly and objectively identify the chanting style of the audio data, and is convenient for classifying and evaluating the chanting style of the chanter.
