Embodiment Construction

[0048] Exemplary embodiments of the present invention will now be described in detail, examples of which are shown in the drawings, in which the same reference numerals always refer to the same elements. The embodiments are described below to explain the present disclosure by referring to the figures.

[0049] In this application, the mobile device uses a mobile phone as an example, but it is not limited to this. For example, the mobile device may also be a portable multimedia player (PMP), a digital broadcast player, a personal digital assistant (PDA), a portable game terminal, a smart phone, and so on.

[0050] figure 1 Is a diagram showing the structure of a system for updating an LM according to an exemplary embodiment of the present invention.

[0051] The mobile phone purchased by the user is pre-installed with a general purpose LM, which is called the initial LM and will be modified to obtain the user's personal language habits and conduct training.

[0052] The system include...

Abstract

The invention provides a system and method for updating a language model (LM). The system comprises a local text set generation unit and an LM updating unit, wherein the local text set generation unit is used for generating a local text set by using text data input to a mobile device and the text data received by the mobile device; and the LM updating unit is used for updating a previously installed initial LM in the mobile device based on the local text set. According to the system and the method, the problem of mismatching between the LM and application requirements in the prior art is solved; and according to the system and method for updating the LM, the LM can be dynamically and frequently updated according to codes of language and concerned topics of a specific user and occurring language phenomenon.

Description

Technical field [0001] The present invention relates to a system and method for updating a language model, and more specifically, to a system and method for updating a language model using local resources and network resources in a mobile device. Background technique [0002] The Language Model (LM) uses statistical methods to describe and model human spoken or written language. The quality of the language model or the degree of conformity between the language model and application requirements greatly affects the performance of application systems (for example, automatic speech recognition (ASR) systems, text input systems, and machine translation systems). [0003] Taking the ASR system as an example, if the tourism field LM is used to recognize spoken sentences in the tourism field, the recognized character error rate (CER) is about 10%. However, if the same LM is used for spoken sentences in the news newspaper field without any other modifications in the experiment, the CER ri...
