Problems solved by technology

In fact, human perception of emotional intensity is continuous, and it is difficult to define or it can be said that there is no boundary between different emotional intensities. Therefore, the speech synthesized by the existing speech synthesis system expressing emotional intensity is difficult to reflect the actual emotional speech. continuity in emotional intensity

Embodiment Construction

[0090] Although existing speech synthesis technologies have been able to generate highly realistic and natural emotional speech, the data-driven approach adopted by these emotional speech synthesis technologies, that is, to synthesize "happy" speech, collect "happy" corpus and construct a representation The acoustic model or splicing database of the "happy" emotional label, and then use this model (or database) to synthesize the "happy" speech. However, how to synthesize speech with different emotional intensities is still a major technical problem in the field of speech synthesis. The specific embodiments of the present invention are mainly used to solve the problem of emotional speech synthesis with adjustable emotional strength, so that the emotional strength of the synthesized speech is continuously adjustable, and can be adjusted independently according to the needs of users, or can be selected through machine analysis. Emotional intensity feature vectors for emotional sp...

Abstract

The invention provides an emotional speech synthesis method and equipment thereof. The method comprises the steps: setting an emotional intensity feature vector for a target synthesis text, enabling the emotional intensity feature vector to generate an acoustic feature vector corresponding to emotional intensity through an acoustic model, and synthesizing speech corresponding to the emotional intensity based on the acoustic feature vector. The emotional intensity feature vector is continuously adjustable, and emotional speeches with different intensities can be generated according to the values of different emotional intensity feature vectors, so that the emotional types of the synthesized speeches are richer. The emotional speech synthesis method and the equipment can be applied to the man-machine interaction process in the field of artificial intelligence (AI) to perform intelligent emotional speech synthesis.

Description

technical field [0001] The invention relates to the field of voice processing, in particular to a voice synthesis method and equipment. Background technique [0002] Artificial Intelligence (AI) is a theory, method, technology and application system that uses digital computers or machines controlled by digital computers to simulate, extend and expand human intelligence, perceive the environment, acquire knowledge and use knowledge to obtain the best results. In other words, artificial intelligence is the branch of computer science that attempts to understand the nature of intelligence and produce a new class of intelligent machines that respond in ways similar to human intelligence. Artificial intelligence is to study the design principles and implementation methods of various intelligent machines, so that the machines have the functions of perception, reasoning and decision-making [0003] With the continuous development of artificial intelligence technology, the natural l...
