Text speech synthesis method after speaker emotion simulated optimization translation

Abstract

The invention discloses a text speech synthesis method after speaker emotion simulated optimization translation. Voice information of a user is obtained; The background analyzes an audio file to obtain frequency and speech speed parameters; the background is introduced to a voiceprint identification system to obtain gender and age parameters; speech is recognized to obtain text information; an emotion parameter is obtained from the text via analysis on grammar, vocabulary and sentences of the text; frequency, speech speed, gender, age and emotion features are combined, and a characteristic value is set for each feature; and the characteristic values are combined with a speech synthesis SSML grammar to set the broadcast speed, volume and word pause in the speech synthesis SSML grammar. Thus, synthesized speech broadcast of another language can reflect the emotion feature of a native language of a speaker. The mood, tone, vocabulary and grammar features of the speaker are identified, sothat the speech translated synthesis broadcast reflect the emotion of the speaker at present.

Description

technical field [0001] The invention relates to a method for speech synthesis, in particular to a method for simulating a speaker's emotion to optimize translated text and speech synthesis, and belongs to the technical field of speech translation. Background technique [0002] The current speech synthesis technology converts text into speech, but simply broadcasts the text mechanically, and cannot accurately express the speaker's emotions. The present invention recognizes the speaker's tone, intonation, words, grammar and other sound and language features, and dynamically adjusts the speech synthesis rules when the speaker's language is translated into other languages, so that the final speech synthesis report faithfully reflects the current speech the emotions of the recipient. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defect that the current speech synthesis technology converts text into speech, whi...
