Speech synthesis method and device, electronic equipment and storage medium

The invention provides a speech synthesis method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining a to-be-synthesized text, and controlling the target emotion intensity of speech synthesis; determining a global emotion feature under the target emotion intensity based on the gear emotion feature of each preset emotion gear; speech synthesis is carried out based on the text and the global emotion characteristics, the defect that the emotion expression effect of the synthesized speech is poor due to the fact that the synthesized speech lacks emotions or is single in emotion expression and lacks conversion between emotions in a traditional scheme is overcome, speech synthesis is controlled through the global emotion characteristics, and the speech synthesis efficiency is improved. According to the method, the emotion direction and the emotion intensity can be positioned in the emotion space, information expression of the synthesized speech on different emotions
