A spectrogram analysis method (100), apparatus (600) and device (700), and a computer readable storage medium. The spectrogram analysis method comprises: acquiring a Doppler spectrogram to be analyzed (S110) recognizing, from the Doppler spectrogram to be analyzed, spectrogram features to be analyzed (S120) and analyzing the spectrogram features to be analyzed by means of a trained classifier to obtain abnormal information, the abnormal information comprising abnormal spectral information about whether abnormal spectrum features exist, and the abnormal spectrum features comprising one or more of the following: stealing, vortex, turbulence and short dash (S130). The spectrogram analysis method (100), apparatus (600) and device (700) and the computer readable storage medium automatically recognize the abnormal spectrum features on the basis of the spectrogram features of the transcranial Doppler spectrogram, such that labor costs can be saved, the efficiency and accuracy of characteristic recognition can be improved, thereby facilitating the improvement of disease diagnosis correctness, and having great application value and wide market prospect.Linvention concerne un procédé (100), un appareil (600) et un dispositif (700) danalyse de spectrogramme, et un support dinformations lisible par ordinateur. Le procédé danalyse de spectrogramme comprend les étapes consistant : à acquérir un spectrogramme Doppler à analyser (S110) à reconnaître, à partir du spectrogramme Doppler à analyser, des caractéristiques de spectrogramme à analyser (S120) et à analyser les caractéristiques de spectrogramme à analyser au moyen dun classificateur formé en vue dobtenir des informations anormales, les informations anormales comprenant des informations spectrales anormales permettant de savoir si des caractéristiques de spectre anormal existent, et les caractéristiques de spectre anormal comprenant un ou plusieurs des éléments suivants : vol, vortex, turbulence et course rapide (S130).
