In various application management systems under development, various query functions are generally realized. How to find qualified records accurately and quickly is the key to realize various query functions.

In the actual development process of the system, the query function is generally realized by comparing and judging characters.

The query mode of personnel management system is that as long as you know the pronunciation of a person's name, but don't know the specific spelling of each word, you can display all records that meet this pronunciation by searching the database. Because there are a large number of homophones in Chinese characters, using common character matching methods, such as looking for a person named Wang Xiaowu, can't find the data named Wang Xiaowu in the database, and using common query methods can't realize the query function of homophones. In order to solve the fuzzy query problem of homophones, the input method generator under Win-dows system is borrowed to generate the pinyin input method dictionary library in the system as the pinyin query dictionary library. Using this pinyin query dictionary library, it is easy to realize the function of voice fuzzy query in the personnel management system written by VFP database management system.
