Research on Fundamental Frequency of Prosodic Parameters in Emotional Speech Synthesis
Emotional Speech Synthesis is a prevalent trend in current speech synthesis technology research.Among all the factors,appropriate emotional prosody model building and prosodic parameter selecting are the key matter.Whether it describes correct or not,will have a direct impact on the outputting effects of the emotional speech synthesis.In order to overcome the difficulty of improving natural degree in emotional speech,the parameters that affect the prosody of emotional speech synthesis technology are analyzed and an emotional prosody model based on association rules is built.This paper studies the association rules,and through improving data mining Apriori algorithm so as to obtain the fundamental frequency changing rules in prosodic parameters,and thus provide guidance and convenience for selecting sound in emotional speech synthesis.
