Abstract: An analysis system and method for audio data related to a user is provided, so that the user can be classified as one of multiple classes with an assumed probability based on the analysis result. The analysis system comprises an audio transformer (110) adapted to transform the audio data related to the user into spectra data; a pattern recognizer (120) adapted to decompose the spectra data to predetermined eigenvectors to get the decomposition pattern of the spectra data; a scorer (130) adapted to calculate the assumed scores of the multiple classes related to the user based on the decomposition pattern of the spectra data and the attributes of the user using a trained model.
