Comparison of Farsi Vowel Intonation with Different Languages for Teaching and Preserving Original Accent

Voice intonation is one of criteria of appropriately expression of phonemes and words, especially in teaching language exert appropriately intonation by person on phonemes and words, regardless of type such as: interrogative, affirmative and etc, are depends on learning. Comparison and reconstruction of voice intonation are two important challenges in Computer Assisted Language Learning. In this paper a method based on discrete signal processing has been presented. By using this method user can see similarity value of own voice intonation with source voice. In addition duration of voice and silent of user sound intervals, reconstruct according to source voice, and the user will be able to hear reconstructed phoneme by own voice. Applications of this method are: teaching standard Farsi pronunciation to the non-Farsi speakers, speech therapy, animation, and E-learning.
