The Design And Development Of Software For Acoustic Feature Analysis Of Teaching Language

Education is a communication process.As a preacher,teachers must have good teaching language skills.The Ministry of Education puts forward high requirements on the teaching language skills of normal students.However,due to the large student-teacher ratio and limited resources in the teaching language skills training process for normal students,the improvement of the teaching language skills of normal students is slow and the effect is not satisfactory.Existing software of voice editing and analysis is not well suited and helpful to the teaching language skills training.Therefore,in the context of U-learning,in accordance with the waterfall model,this research uses a design-based research paradigm to design and develop an auxiliary software which can provide "ubiquitous training" for teaching language skills training.The software can record,analyze and give feedback on the volume,speed,pause,and emotional to normal students.Through software testing,teacher interviews,student trials,etc.,various functions of the software will be modified and improved.According to the students ’ data recorded by the software,the user’s acceptance and effectiveness of the software will be verified.According to the research process,this thesis is divided into six chapters: the introduction part mainly introduces the research background,research questions,research goals,research content,research methods,technical routes and research significance;the research status part,the research status of the teaching language skills Summarize,define concepts,sort out the functions and characteristics of existing speech analysis software,and explain the theoretical basis of related research;the design part of teaching software introduces demand analysis,architecture design,interface design,interaction and feedback design and functions design;the development part of the teaching software introduces the development methods of the software interface and functions;the trial and improvement part of the teaching software revises and perfects the various functions of the software through voice tests,teacher interviews and student trials,and analyzes according to the trial results Markov chain analyzes the effectiveness of teaching software;the conclusions and suggestions section analyzes the effectiveness of different functions of the software in helping normal students to improve their teaching language skills,and summarizes the methods and suggestions for designing and developing supplementary teaching language skills software,And reflected on the deficiencies of this research.The following conclusions are drawn through the research: The acoustic feature analysis software of the teaching language has played a supporting role in the independent training of the teaching language skills of the normal students;the software has significant training effects in the speed,pause,and emotion of the teaching language skills,and there is still a sound volume.insufficient.Therefore,this research suggests that in the subsequent design and development of instructional language skills assistance software,one can try to shift from single-dimensional analysis to multi-dimensional analysis.The combination of acoustic characteristics of different dimensions can more effectively provide evaluation and evaluation of instructional language skills training.Feedback: From the overall speech analysis to the sentence analysis,the sentence-by-sentence analysis can make the analysis results of the software more accurate and detailed,so that the evaluation and feedback of the software are more credible and effective.Due to time and energy constraints,this research needs to be further improved in the development of software functions in order to optimize the software and provide more effective help for teaching language skills training.
