Abstract

The embodiment of the invention provides a voice synthesis method and device. The voice synthesis method includes the steps that phoneme characteristics and rhythm and affective characteristics of a to-be-processed text are obtained; according to the phoneme characteristics and the rhythm and affective characteristics, the voice duration of the to-be-processed text is determined through a pre-trained duration model, wherein the duration model is obtained based on convolutional neural network training; according to the phoneme characteristics, the rhythm and affective characteristics and the voice duration, acoustic characteristic parameters of the to-be-processed text are determined through a pre-trained acoustic parameter model, wherein the acoustic parameter model is obtained based on convolutional neural network training; according to the acoustic characteristic parameters, a voice of the to-be-processed text is synthesized. By means of the voice synthesis method in the embodiment,on the premise that the real-time requirement can be met, the synthesized voice which is higher in voice quality, better in emotion expressiveness and more natural and smoother can be provided.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of Text To Speech (TTS for short), and in particular, to a method and apparatus for speech synthesis. Background technique [0002] With the continuous development of multimedia communication technology, speech synthesis technology, which is one of the important ways of human-computer interaction, has attracted extensive attention of researchers because of its convenience and speed. Speech synthesis is a technology that generates artificial speech by mechanical and electronic methods. It is a technology that converts text information generated by a computer or input from external sources into comprehensible and fluent spoken language output. The purpose of speech synthesis is to convert text into speech and play it to the user, and the goal is to achieve the effect of real text broadcasting. [0003] Speech synthesis technology has been widely used, for example, speech synthesis techno...
