Problems solved by technology

[0003] In the existing technology, whether it is dictionary generation or corpus generation, it must rely on manual screening and token segmentation, so the update cycle is long and the existing tokenizer is too dependent, and unregistered entries or corpus cannot be recognized

Abstract

The invention provides a generation method and device for a word segmentation dictionary and a word segmentation processing method and device. The generation method for the word segmentation dictionary comprises the following steps: acquiring an original sentence and language material; segmenting the original sentence and language material to obtain segments, and filtering the segments to obtain a filter result, wherein the filtering step comprises at least one of the following steps: carrying out filtering based on word frequency and inverse frequency; carrying out filtering based on boundary; and carrying out filtering based on splicing; and generating the word segmentation dictionary according to the filter result. The method, which is independent of manual screening and a word segmentation apparatus, can be used for recognizing entries which are not logged in, so that the generation speed and effect of the word segmentation dictionary are improved.

Description

technical field [0001] The invention relates to the technical field of speech processing, in particular to a method and device for generating a word segmentation dictionary and a method and device for word segmentation processing. Background technique [0002] Speech synthesis, also known as text to speech (Text to Speech), can convert text information into speech and read it out in real time, which is equivalent to installing an artificial mouth on a machine. For speech synthesis systems, the input text needs to be processed first, including word segmentation. There are two main types of word segmentation algorithms, one is an algorithm based on dictionary matching, and the other is a learning algorithm based on training corpus. The dictionary and the training corpus are the necessary data for the matching algorithm based on the dictionary and the learning algorithm based on the training corpus respectively. [0003] In the existing technology, both dictionary generation ...
