Embodiment Construction

[0028] In order to enable those skilled in the art to better understand the solutions of the embodiments of the present invention, the embodiments of the present invention will be further described in detail below in conjunction with the drawings and implementations.

[0029] The embodiment of the present invention realizes the method and system for automatically adding punctuation marks in speech recognition, by performing speech recognition on the collected user voice signal, generating a text sequence containing a plurality of sentences; and sequentially calculating the duration of pause positions between sentences in the text sequence ; If the duration is less than the preset threshold value, then add a comma at the pause position; if the duration is greater than or equal to the threshold value, then determine the tone type of the sentence before the pause position, and according to the determined sentence type Add punctuation at that pause. Therefore, the automatic additi...

Abstract

The invention relates to the technical field of speech recognition and discloses a method and system for realizing automatic addition of punctuation marks in the speech recognition. The method comprises the steps of: collecting user speech signals; carrying out the speech recognition on the user speech signals so as to generate a character sequence containing a plurality of sentences; sequentially calculating duration of pause positions between the sentences in the character sequence; if the duration is less than a preset threshold value, adding commas at the pause positions; and if the duration is greater than or equal to the preset threshold value, confirming the mood types of the sentences in front of the pause positions by utilizing a pre-generated classifier and adding punctuation marks at the pause positions according to the types. By utilizing the method and system which are provided by the invention, the automatic addition of the punctuation marks can be simply and conveniently realized and the accuracy and the flexibility of adding the punctuation marks are increased.

Description

technical field [0001] The invention relates to the technical field of speech recognition, in particular to a method and system for automatically adding punctuation marks in speech recognition. Background technique [0002] At present, most speech recognition systems use methods based on statistical pattern recognition. First, the time-domain sound waves of speech input are converted into a digital vector feature to describe and distinguish different pronunciations, and an acoustic model is established for all pronunciations based on the sound features; At the same time, for the continuous speech recognition system with a large vocabulary, a language model is needed, which includes the usage methods of commonly used words in the recognized language. The working process of a general continuous speech recognition system can be described as, in a huge space of words, words, phrases or sentences, find the word, word, phrase or sentence that matches the given input sound feature ...
