Method for selecting primitives for synthesizing Chinese voice based on characters of rhythm

A prosodic feature and speech synthesis technology, applied in speech synthesis, speech analysis, instruments, etc., can solve the problems of complex prosody model and prosody control, unable to meet the requirements of prosody features and prosody control of speech synthesis, and meet the requirements of prosody change Complex and changeable effects that reduce difficulty

Embodiment Construction

[0045] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0046] In this embodiment, the input target sequence is the phonetic code string marked with prosodic information after the text analysis processing module has processed it, i.e. the prosodic tagging sequence. The present invention adopts the primitive selection method based on the prosodic feature from The appropriate speech primitives are selected from the speech database for further speech synthesis processing by the speech synthesis program.

[0047] This embodiment includes the following computer-implementable steps:

[0048] input target primitive sequence;

[0049] In the step of determining primitives, the input target primitive sequence is sent to the statistical module for processing, and the candidate primitive sequence corresponding to the target primitive sequence is selected from the speech database according to the index by stati...

Abstract

A method for selecting voice synthetic primitive of Chinese based on rhythm character includes outputting object primitive sequence, outputting primitive sequence to matching process, outputting candidate primitive sequence with matched rhythm character to pasting-up step, judging and selecting candidate primitive sequence to optimization-screening step according to pasting-up cost and optimization screening out primitive sequence for voice synthetic program.

Description

(1) Technical field [0001] The invention relates to the technical field of speech signal processing, in particular to a method for selecting Chinese speech synthesis primitives based on prosodic features. (2) Background technology [0002] The relevant primitive selection method in the existing speech synthesis technology generally adopts a statistical primitive selection method or a regular primitive selection method. The statistical primitive selection method is suitable for large-scale primitive selection, while the regular primitive selection method is suitable for primitive selection in some special cases. In practice, it is found that the prosodic model and prosodic control of Chinese are extremely complex, and the primitive selection method based on one method cannot meet the requirements of speech synthesis for prosodic features and prosodic control in the current situation. Because Chinese prosody is changeable, even the same sentence will produce different prosodi...
