The Design And Implementation Of Intelligent English Pronunciation Training System Based On Android Platform

In recent years, as more and more Chinese people are learning English, many kinds of Englishlearning softwares appear, but most of them are lack of effective evaluation and feedback forpronunciation. However, in the learning of English pronunciation, effective feedback incentive isvery important, especially for non-native speakers of English learners. This question has become abottleneck in the development of intelligent English learning software.With the maturity of voice recognition technology, some people at home and abroad began to dothe research on applying speech recognition technology to pronunciation learning, however, most ofthem stay in the theoretical level, only a small amount of mature application are large systems basedon the computer platform, this provides a big development space for portable and intelligentpronunciation training system based on mobile platform. With the rapid development of mobileinternet technology, the share of intelligent mobile phone is becoming larger. As an outstandingsmartphone operating system, Android system developed rapidly in recent years, the share of theAndroid smartphone has reached up to80%. Android smart phone not only has powerful dataprocessing ability and flowery graphical user interface, but also has rich development componentswhich make it quick and convenient to development applications. Compared to traditional computersoftwares, the software on the Android smartphone is more convenient and practical. So developinga portable and popular English pronunciation learning system with pronunciation feedback functionbased on the Android platform has a strong meaning.This paper is to develop a multi-function English pronunciation training system with thefunction of listening, repeating, and pronunciation assessment based on Android smartphoneplatform, so as to make the learning of English pronunciation popular and covenient.This paper contains the theoretical research and application development. First of all, theresearch studies the theory of speech recognition, and discusses voice ratings and pronunciationcorrection algorithm. In allusion to the question that pronunciation rating is inaccurate and lack ofeffective feedback when speech recognition technology is applied to verbal learning, the researchputs forward an assisted learning system based on the method of AP rating and the technology ofpronunciation resonance peak contrast. Then, according to the characteristics of the Androidplatform the research provides a feasible technical scheme for the development of oral Englishtraining system. Finally, by programming in Java language for the relevant algorithm and software interface in Eclipse integrated environment, the system is realized in the zte V880Android OS2.2mobile platform. This paper introduces specific technical realization of each module, and providesimplementation details and codes for some core modules. This English pronunciation trainingsystem based on the Android smartphone platform has accomplished all the expected functions,includes the reading and repeating, real-time evaluation and pronunciation correction for Englishphonetic symbol and word pronunciation. According to the test, the pronunciation assessment ofthis system has high accuracy. For word and vowel pronunciation, the similitude degree between thesystem assessment and expert evaluation is above90%, and the efficiency of pronunciationCorrection reached to80%, which means to a certain extent the system can improve the learners’pronunciation.
