摘要:PROBLEM TO BE SOLVED: To convert whispering voice to normal voices. SOLUTION: A whispering voice analyzing means 12 performs an analysis of whispering voices in the large amount of learning data and extracts whispering spectrum information. Moreover, a normal voice analyzing means 13 performs an analysis of normal voices in the data and extracts normal spectrum information. A mapping function estimating means 14 estimates a mapping function from the pair of large amount of the whispering spectrum information and the normal spectrum information and stores them. When whispering voice are inputted, an input voice analyzing means 11 performs a voice analysis and extracts input spectrum information. A spectrum converting means 15 converts the information to converted spectrum information by the mapping function. A voice synthesizing means 16 synthesizes normal voices from the information and outputs them.
