Abstract:
     This invention relates to method for identifying and confirming an identity by the soundwave information of mankind including a model training method and a soundwave identification method characterizing in that every speaking person makes up of soundwave model: M=***, the character vector sequence to be identified x'={X1,...XT} matching with the speaking person soundwave model M=*** gets marks (log likelihood) as 1:s(x'/M)=***. This invention can adjust threshold value of an operation point according to different requirements to reach the highest accurate rate.
