Abstract

An embodiment of the invention discloses a speech synthesis method and a speech synthesis device. When acquiring a speech synthesis request, corresponding neutral speech acoustic parameters can be determined according to at least one semantic unit contained in a language segment of a speech to be synthesized and by means of a statistical model established based on neutral speech acoustic parameters, and the determined neutral speech acoustic parameters are processed correspondingly according to mood characteristics of a specific mood to obtain a specific mood segment in the specific mood. Therefore, the speech synthesis method and the speech synthesis device can synthesize the specific mood segment according to the statistical model established based on the neutral speech acoustic parameters and the mood characteristics without recording speeches in a large amount of specific moods in advance, thus the cost of speech synthesis is reduced; and the speech segment in the required mood canbe synthesized for any mood by adopting the statistical model and the corresponding mood characteristics, thereby greatly enlarging the application range of the speech synthesis scheme.

Description

technical field

[0001] The invention relates to the field of data processing, in particular to a speech synthesis method and device. Background technique

[0002] With the development of computer technology, many interactive scenarios require data processing equipment to directly or indirectly perform voice interaction with users, such as voice prompts in electronic navigation, rush answers and voice answers in robot answering sessions, etc.

[0003] Since the voices emitted by the machine are basically synthesized by the machine and used to simulate human language, the pronunciation of this type of voice is cold and has no emotional color, so this type of voice does not bring users a good feeling. In order to improve the user experience during the interaction process, the voice produced by the machine needs to reflect the proper tone according to the context.

[0004] The traditional method is to collect a large amount of corpus with this tone in advance for a certain tone...
