AI Technical Summary

Technical Problem

Existing technologies for predicting Tibetan prosodic structure lack effective modeling of the dynamic relationship between grammatical information and prosody, leading to confusion about pauses and increased comprehension burden.

Method used

By using a grammatical information-based method, Tibetan text parsing and function word continuation quantification are completed. Grammatical probabilities, hierarchical focus and pause differences are extracted, boundary discrimination and entropy feature analysis are performed, function word anchor point marking, clause skeleton adjustment and pause compression are executed, a three-layer prosodic boundary type sequence is generated and excessively dense pauses are suppressed.

Benefits of technology

It achieves accurate identification of prosodic boundaries, stable anchoring of grammatical functions, dynamic adjustment of phrase hierarchy subdivision and rhythm alignment, optimizes the reasonable allocation and rhythm coordination of Tibetan prosodic structure, and solves the problems of inaccurate boundary determination, unstable grammatical functions and unnatural rhythm in existing technologies.

Abstract

The application discloses a Tibetan prosody structure prediction method based on syntax information, relates to the technical field of speech synthesis, and is applied to the prosody structure prediction field in Tibetan speech synthesis. The Tibetan prosody structure prediction method based on syntax information comprises the following steps: S1, Tibetan text analysis and virtual word connection quantization are completed, syntax probability, hierarchical focus and pause difference are extracted, and a Tibetan prosody prediction database is stored and constructed after preprocessing; S2, boundary discrimination is performed based on virtual word connection relationship strength, influence range hit marking and word sequence distance; S3, entropy feature analysis is performed through syntax role probability data and boundary determination data; S4, three-layer prosody boundary type sequences are generated according to boundary assignment, and over-dense pauses are inhibited; and S5, rhythm intensity evaluation is performed through pause duration difference and syntax information entropy data. The problems of pause confusion and increased understanding burden caused by the misplacement of prosody and semantic hierarchy in Tibetan long speech synthesis are solved.
