Abstract: A system and method for using pinyin and a dynamic memory state for modifying a Hanyu vocabulary test are provided. The system uses a Chinese input method for conducting the Hanyu vocabulary test, and includes an input device, an output device, a computing processing device, and a word database. The computing processing device includes a user login verification unit, a screening and sampling unit, a grading and timing unit, and a recording and analyzing unit. The user uses the input device and output device to operate the system. After the user is verified by the user login verification unit, the screening and sampling unit samples a test bank from the word database based on the test record of the user. The grading and timing unit calculates the answering time and determines if the user has answered the questions correctly. The recording and analyzing unit records and analyzes a test result of the user, and then stores the test result to the word database.
