Psc Word, The Word Computer, Automatic Contrast System Design Studies

As our great motherland is developing, the application of our standard language - Putonghua is showing higher and higher status and becoming one of the state language policies. Going with the language tide of standardization and normalization, and based on "the Phonetic distinctive feature database system of grade-rule for Putonghua-standard-examination", the paper, appreciating the experimental data and relevant theories of experimental phonetics and computer phonetic processing technology, designs a set of software system which is operable, extendable and applicable (operational, extensive and practical), with the goal of increasing the justice level of the examiner and the language level of the examinee. The paper also supplies an examine rule for the examiner and the examinee to make a precise understand about the Sandra language examination. The paper mainly discusses the software system about the design precondition, theoretical foundation and the detailed design-stages. After making a full thought on the previous computer phonetic processing and recognition technology, the author devotes the paper to the designation of phonetic samples, phonetic boundary detection, phonetic auto-segmentation, the design of phonetic distinctive feature database, the memory ways for store phonetic data, the contrastive contents about words and phrases on PSC examine papers and the design of the system window. The author also offers a typical flow diagram and a program about using the Visual Studio software to draw procedures which plays an important role on the realization about the final success of the software system discussed on this paper.
