STATISTICAL PARAMETER MODEL ESTABLISHMENT METHOD, SPEECH SYNTHESIS METHOD, SERVER AND STORAGE MEDIUM

摘要

A statistical parameter modeling method is disclosed, including: obtaining, by a server, model training data, the model training data including a text feature sequence and a corresponding original speech sample sequence; inputting, by the server, an original vector matrix formed by matching a text feature sample point in the text feature sample sequence with a speech sample point in the original speech sample sequence into a statistical parameter model for training; performing, by the server, non-linear mapping calculation on the original vector matrix in a hidden layer, to output a corresponding prediction speech sample point; and determining, by the server, a model parameter of the statistical parameter model according to the prediction speech sample point and a corresponding original speech sample point by using a smallest difference principle, to obtain a corresponding target statistical parameter model.
