Problems solved by technology

Because the voice generation of Tacotron2 under the tensorflow development platform is a non-streaming method, and the voice will be output after the overall processing of the text content is completed, so the user experience is reduced

Abstract

The invention relates to a voice synthesis method and device, equipment and a storage medium. The method comprises the following steps: obtaining a text vector after encoding a target text to be subjected to speech synthesis; obtaining a first vector segment obtained by decoding the text vector, and a first attribute feature corresponding to the first vector segment; wherein the first attribute feature at least can represent a word order position feature corresponding to the first vector fragment in the text content of the target text; performing voice synthesis processing on the first vectorsegment to obtain and output a first voice segment; and obtaining a second vector segment at least based on the text vector and the word order position features represented by the first vector segmentand the first attribute features. Thus, the purpose of converting stream output into stream output is achieved, a foundation is laid for reducing the overall output time, and meanwhile a foundation is laid for improving user experience.

Description

technical field [0001] The present application relates to the field of speech synthesis, in particular to a speech synthesis method, device, equipment and storage medium. Background technique [0002] In voice interaction scenarios, when text content needs to be converted into voice, fast and high-quality voice response is required. However, although the existing neural network synthesis solutions are of high quality, the synthesis speed is very slow. Taking the end-to-end neural network synthesis solution Tacotron2 as an example, if the CPU is used to decode it under the tensorflow development platform, it takes about 2.5 seconds to wait for a sentence of 5 seconds. The time can be generated, and the longer the voice time, the longer the waiting time. Because the voice generation of Tacotron2 under the tensorflow development platform is a non-streaming method, the voice will be output after the overall processing of the text content is completed, thus reducing the user exp...
