Embodiment Construction

[0038] It should be understood that the specific embodiments described here are only used to explain the present application, not to limit the present application.

[0039] The embodiment of the present application provides a language model fusion method. In the first embodiment of the language model fusion method of the present application, refer to figure 1 , the language model fusion method is applied to a language model fusion device, and the language model fusion method includes:

[0040] Step S10, acquiring the speech data of the target language scene, and extracting the speech-to-text scoring data for converting the speech data into text data and the word error rate data corresponding to the text data;

[0041]In this embodiment, it should be noted that the target language scene is a language scene that requires speech recognition based on a fusion language model, for example, a meeting scene, a news scene, a chat scene, etc., and the text data includes at least one tex...

Abstract

The invention discloses a language model fusion method and device, a medium and a computer program product, and the method comprises the steps: obtaining voice data of a target language scene, and extracting voice-to-text scoring data for converting the voice data into text data, and word error rate data corresponding to the text data; acquiring confusion score data of a to-be-fused language model corresponding to each preset language scene on the text data, and combining each confusion score data, the voice-to-text score data and the word error rate data to obtain combined training data; based on the combined training data, constructing a classification sorting model; and based on the model weight parameters of the classification sorting model, performing weighted fusion on the to-be-fused language models to obtain a fused language model. The technical problem that the language model fusion effect is poor is solved.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence in financial technology (Fintech), and in particular to a language model fusion method, device, medium and computer program product. Background technique [0002] With the continuous development of financial technology, especially Internet technology finance, more and more technologies (such as distributed, artificial intelligence, etc.) The industry also has higher requirements for the distribution of to-do items. [0003] With the continuous development of computer technology, the application of artificial intelligence is becoming more and more extensive. At present, when performing speech recognition in a new language scene, due to the lack of data in the new language scene, the data of each language scene is usually The language model is fused to obtain a fusion language model adapted to the new language scene. At present, based on the corpus correlation correspondin...
