Embodiment Construction

[0021] In order to make the purposes, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments These are some embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] like figure 1 Shown is a flowchart of an inverse text standardization method provided by an embodiment of the present invention, including the following steps:

[0023] S11: Extract keywords in multiple original speech recognition results concurrently output by the recognition module;

[0024] S12: Perform scene division on...

Abstract

The embodiment of the present invention provides an inverse text normalization method. The method includes: extracting keywords in multiple original speech recognition results concurrently output by a recognition module; dividing the multiple original speech recognition results into scenes based on the keywords to determine the scenes of the multiple original speech recognition results; The speech recognition results are input into the ITN resources corresponding to the respective scenarios, and a plurality of inverse text-standardized speech recognition results are output. The embodiment of the present invention also provides an inverse text normalization system. It can be seen from the implementation manner of the embodiment of the present invention that in the divide and conquer computing mode, the occupation of computing resources of the online ITN is greatly reduced, and higher service capability is provided at a lower cost. More flexible support for standardized conversion of user-specific words. For scenarios that cannot be efficiently supported by some scenario rules, perform in-depth model optimization, and you can also avoid problems that cannot be solved by the model by adding bad cases to the rules of other scenarios.

Description

technical field [0001] The invention relates to the field of intelligent speech, in particular to a method and system for inverse text standardization. Background technique [0002] ITN (Inverse Text Normalization, Inverse Text Normalization) is a necessary processing process after intelligent speech recognition. Taking Chinese and English recognition as an example, the recognized texts are all Chinese and English words without numbers and symbols. But from the perspective of our writing habits, some expressions in standardized formats will conform to reading habits, such as dates, percentages, phone numbers, etc. ITN is used to perform this layer of standardized transformation on the recognition results. [0003] In the process of realizing the present invention, the inventor found that there are at least the following problems in the related art: [0004] When the ITN function is turned on, the recognition results obtained each time will be used as the input of the ITN ...
