Abstract

The invention relates to a portable interpretation system based on a WinCE platform, which comprises a voice collector, a voice preprocessing module, a voice feature extraction and modeling module, a model base, a recognition module, a corpus base and an interpretation and voice synthesis module, wherein all the modules are established on an embedded platform; the voice collection module is connected with the voice preprocessing module; the voice preprocessing module is connected with the voice feature extraction and modeling module; the voice feature extraction and modeling module is respectively connected with the model base or the recognition module; when a training state is selected, the voice feature extraction and modeling module is connected with the model base; when a recognition state is selected, the voice feature extraction and modeling module is connected with the recognition module; the recognition module is connected with the interpretation and voice synthesis module; and the interpretation and voice synthesis module is connected with the corpus base. The portable interpretation system has the characteristics of high voice recognition efficiency, high recognition accuracy, high equipment portability and two-way interpretation.

Description

technical field [0001] The invention relates to the technical field of voice recognition, in particular to a portable oral translation system based on the WinCE platform, which is used to recognize voice signals sent by people and convert them into corresponding translation results. The invention also relates to the speech recognition method of the translation system. Background technique [0002] Speech recognition technology is a technology that allows machines to convert voice signals from people into corresponding texts or make setting commands through recognition and understanding. It is gradually becoming the key technology of human-machine interface in information technology. In recent years, with the rapid development of embedded devices, consumer electronics products have penetrated into various fields of our lives, and their characteristics of portability and low cost have been widely used. Therefore, the embedded speech recognition system has great potential cons...
