Putonghua Test System Development And Research

Mandarin test system utilizes the computer to solve the limitation of manual test. It is useful to units?the test standard, overcomes the shortcoming of subjective awareness, makes up the shortage of testers and popularizes the mandarin. The system is developed by Visual C++. It can test the speech level of the speaker by comparing the speaker抯 speech with the speech library and analyzing the data. This system mainly tests the words and phrases. A lot of experiment data, noise and repeated words are analyzed in my paper. These test results show that the recognition rate of words and phrases can reach 70 percent and more than 85 percent. So we can say it is possible to test mandarin by utilizing speech recognition technique. At the same time, some detailed schemes to eliminate the noise, repeated words are brought forward in the paper. In this system, I utilize the powerful c plus to encapsulate the speech interface. It can be used by anyone and is a good way for last development. It has realized the communication between application with engine including open, connection, close, engine management, speech library management, and grammar management. It is still a long term that Mandarin test system can be applied. But with the development of artificial intelligence, it will be more intelligent.
