13. The method of prosody parsing according to claim 11 , wherein said prosody statistic model includes a plurality of token pairs and pause probabilities at associated positions of each of said plurality of token pairs, said step of calculating a pause weight for each pause position in said token sequence comprises: calculating a pause weight for each pause position in said token sequence according to the pause probabilities at associated positions of corresponding token pairs in the prosody statistic model.
14. The method of prosody parsing according to claim 13 , wherein the associated positions of each token pair includes before, after and amid said token pair, said step of calculating a pause weight for each pause position in said token sequence comprises: calculating the pause weight for each pause position with 
 weight=−log(Prob ttp ×Prob tpt ×Prob ptt ) wherein Prob ttp represents the pause probability after the token pair that is located before said pause position, Prob ptt represents the pause probability before the token pair that is located after said pause position, and Prob tpt represents the pause probability amid the token pair that is located across said pause position.
