HTK-based speech recognition and corpus-based English vocabulary online guiding system
Tóm tắt
With the popularization of computers and the development of modern educational technology, the connection between corpus and foreign language intelligent guiding is getting closer and closer. Corpus was first used in vocabulary guiding in foreign language guiding, and there are many research achievements in this field. However, in practical guiding, English vocabulary teaching is a big problem faced by teachers and students. This thesis mainly studies the English vocabulary online instruction system from the perspective of speech recognition. English vocabulary online guidance system has become an essential tool for English learners to learn vocabulary. Speech recognition technology is the technology that converts speech signals into text. Automatic speech recognition is also known as speech recognition or computer speech recognition, its goal is to let the computer can recognize the continuous speech that different people speak, to achieve the conversion of voice to text. Speech recognition is a comprehensive technology that integrates many subjects, including phonetics, linguistics, computer science and so on. Hence, this paper analyzes the HTK speech recognition technology and the construction of the corpus, and studies the English vocabulary online guidance system. The novel speech analysis technology is considered for the implementations of the novel guiding system. Through the comparison simulations compared with the other state-of-the-art systems, the designed outperformed.
