Abstract

The invention provides a voice synthesis method and device, electronic equipment and a computer readable storage medium. The method comprises the steps of decomposing a target text into a plurality ofphonemes, and determining a context feature of each phoneme; performing duration prediction processing on the context feature of each phoneme to obtain a prediction duration of each phoneme; performing extension processing on the context feature of each phoneme based on the prediction duration of each phoneme to obtain an extension feature of each phoneme; performing acoustic feature prediction processing on the extended features of each phoneme to obtain acoustic features of each phoneme, and synthesizing the acoustic features of each phoneme into text acoustic features; and converting the text acoustic features into voice signals. According to the invention, the voice synthesis efficiency can be improved.

Description

technical field [0001] The present application relates to artificial intelligence technology, and in particular to a speech synthesis method, device, electronic equipment and computer-readable storage medium. Background technique [0002] Artificial Intelligence (AI) is a comprehensive technology of computer science. By studying the design principles and implementation methods of various intelligent machines, the machines have the functions of perception, reasoning and decision-making. Artificial intelligence technology is a comprehensive subject that involves a wide range of fields, such as natural language processing technology and machine learning / deep learning. With the development of technology, artificial intelligence technology will be applied in more fields and play an increasingly important role. increasingly important value. [0003] Among them, speech synthesis, as an important branch of natural language processing technology, has also entered a new stage of deve...
