基于MFCC的語音情感特征提取研究
[Abstract]:In order to study the audio classification of the classic ancient books of the "World Memory Heritage" of Dongba, the audio classification of Dongba was identified by the method of speech emotion feature extraction, and the emotional state recognition of the classic voice of Dongba was realized and the human computer interaction performance was improved. The Mel frequency cepstrum coefficient (MFCC) was used to extract the emotion feature of the speech. After introducing the first order difference of MFCC, the two order difference describes the dynamic characteristics of the speech feature, and integrates the short time energy characteristics, and finally forms the feature parameters of the speech signal which is superimposed by the MFCC and the short-time energy, and achieves the purpose of extracting the emotional characteristics of the speech. The experimental verification shows that the speech signal feature extraction method can be more clearly divided in the region. The emotion information contained in speech provides a theoretical basis for the recognition of speech emotion characteristics and the audio classification and identification of Dongba ancient books.
