Problems solved by technology

Because there are still many unavoidable problems in text analysis and prosody prediction, the traditional speech synthesis system cannot accurately grasp the content of the text and the prediction of prosody parameters, and cannot well control the connection between various speech synthesis units. Well control the cadence of synthesized speech, which ultimately leads to the user's unsatisfactory speech

Abstract

The invention provides a voice synthesizing apparatus and a method based on rhythm reference. The voice synthesizing apparatus comprises a rhythm parameter acquiring part and a sound composing part, wherein the rhythm parameter acquiring part acquires natural rhythm parameters or proximate natural rhythm parameters by analyzing voice record files acquired by ways including the way that natural person reads texts to be synthesized or analyzing rhythm parameter label files acquired by labeling rhythm parameter for texts to be synthesized with a predetermined label standard; and the sound composing part uses the natural rhythm parameters or proximate natural rhythm parameters as references, selects corresponding voice synthesizing units from a pre-record voice library aiming at the texts to be synthesized and splices to synthesize the voice synthesizing units to generate synthesized voice files corresponding to the texts to be synthesized. Highly natural, motional synthesized voices having cadence extremely close to natural voices are generated according to requirements of users according to the synthesizing apparatus and method.

Description

technical field [0001] The present invention relates to a device and method for speech synthesis based on prosodic reference. More specifically, the present invention relates to using the prosodic features obtained from natural speech or prosodic feature annotation files based on specific standards as a reference to synthesize speech with A device and method for synthesizing speech with high naturalness. Background technique [0002] Speech synthesis (Text-To-Speech, TTS for short) is a technology for converting text to speech, specifically, a technology for converting arbitrary text information into standard, fluent speech. Speech synthesis involves many cutting-edge high-tech technologies such as natural language processing, prosody, speech signal processing, and sound perception. It spans multiple disciplines such as acoustics, linguistics, and digital signal processing. It is a cutting-edge technology in the field of Chinese information processing. . [0003] Speech sy...
