ABSTRACT:
Upon selection of an expression for pronunciation training, a look-up operation is performed in a speaker database (15) to obtain a predetermined model for comparison with a voice of a user received at an input (11). A speech modeling element models speech of a native speaker. The voice input is applied to the modeling element (102-107) and an analysis is carried out of the comparison, in correlation and in duration, between a phoneme or sub-word of the input and a phoneme or sub-word of the native speaker to provide a score, including a score for the correlation and a score for the duration. The score is analyzed with respect to a score for a predetermined speaker in an analysis element (40). An indicator device (16) coupled to the output of the analysis element indicates the result in a graphical illustration. A tracking tool indicates state of progress of the voice of the speaker.
