Research On The Design Of Ancient Poetry Recitation Game Based On Voice Evaluation Technology

Ancient poetry is an important part of Chinese culture."No poetry,no words." Reading and reciting ancient poetry has far-reaching significance for primary school students: it can not only exercise language ability,promote the learning and understanding of Chinese course,but also expand cultural horizons and enrich the spiritual world.However,the problem of ignoring reading ability and situational understanding is common in the education of ancient poetry.Primary school students have limited cognition of ancient poetry.Digital technology has brought new modes and methods to ancient poetry education:educational game is a kind of education mode which includes teaching and pleasure.Voice evaluation technology makes ancient poetry recitation practice have intuitive and clear feedback,and augmented reality technology makes ancient poetry situation display three-dimensional and vivid.Therefore,the organic combination of digital technology and ancient poetry recitation education will bring new vitality to ancient poetry education,which is a topic worthy of study.The voice evaluation system is a part of the ancient poetry recitation game.According to the characteristics of the ancient poetry recitation,the voice evaluation system is analyzed and the system architecture is determined.Speech signal preprocessing,feature extraction and pattern matching are performed in turn.In the feature extraction part,the pitch rate and short-term energy are added to reflect the prosodic features of the speech signal.Based on the characteristics of the target user group,the demand analysis and function design of the ancient poetry recitation game are carried out,and the design principles,interface and interaction design criteria of the game are determined.The interactive experience flow of the system is designed by combining the functions of introducing ancient poems,reciting exercises and augmented reality games.Unity 3D and Vuforia SDK are used for function development.Using the heuristic evaluation method,analyses the usability of the ancient poetry recitation game from the aspects of interface display,interactive experience and function perfection,finds out the problems and puts forward the improvement plan.By using the method of comparative experiment,the effect of ancient poetry recitation game on the improvement of recitation ability was verified.User interviews were used to understand the experience of pupils andprimary school teachers on ancient poetry recitation games.By using the comparative experiment method,the speech evaluation effect of different feature parameters is compared,and the better feature parameters are selected to achieve the function of recitation scoring.To sum up,the ancient poetry recitation game based on voice evaluation technology tries to use the form of educational games to assist the ancient poetry education,use voice evaluation technology and augmented reality technology to train users' recitation ability,help users understand the situation of ancient poetry,and provide new ideas for the application of digital technology in the field of education.
