Abstract
Disclosed are an accent detection method, an accent detection device and a non-transitory storage medium. The accent detection method includes: obtaining audio data of a word; extracting a prosodic feature of the audio data to obtain a prosodic feature vector; generating a spectrogram based on the audio data to obtain a speech spectrum feature matrix; performing a concatenate operation on the prosodic feature vector and the speech spectrum feature matrix to obtain a first feature matrix, and performing a redundancy removal operation on the first feature matrix to obtain a second feature matrix; and classifying the second feature matrix by a classifier to obtain an accent detection result of the audio data.
