As far as China is concerned, my country has a vast territory and many dialects.It is impossible to count exactly how many dialects there are.According to the large dialect area, the academic circles generally classify Chinese dialects into seven categories, including northern dialects, Fujian dialects, Wu dialects, Cantonese dialects, Gan dialects, Hakka dialects, and Xiang dialects.Among them, the northern dialect is used by the largest population, accounting for more than 7% of the total Han population.The official language spoken by officials during the Ming and Qing Dynasties was based on the northern dialect, so it was also called the Mandarin dialect.Putonghua is based on Beijing phonetics as the standard tone, northern dialect as the basic dialect, and typical modern vernacular writings as the grammatical norms.At present, most of the languages learned and imitated by the hearing impaired during the speech rehabilitation period are Mandarin. When the hearing impaired hears unfamiliar voices, it is still more difficult to understand the information that is not familiar to them.
Researchers found that even in the same language, when people understand speech in different accents or dialects, foreign accents (dialects) are often more difficult to understand than local accents (dialects), and the language information people obtain is more difficult to remember.
There are many factors that affect the communication of the hearing impaired. In addition to hearing factors, speech rehabilitation degree and time, differences in language understanding and experience can also cause differences in speech discrimination.

The functions of various human organs are used to “use advancement and disuse”, and the same is true for hearing-impaired children. Auditory training is for hearing-impaired children. The auditory organs carry out planned sound stimulation and establish stimulus connections, thereby gradually forming a kind of training for the concept of hearing. When the hearing impaired conducts speech rehabilitation training mainly in Mandarin in the speech rehabilitation school, the teacher is the future of the hearing impaired The objects of contact are those taught by Mandarin speakers as imaginary objects. When the hearing impaired actually faces people with different accents or dialects, the understanding ability will often be slightly worse than that of the hearing person, and this situation will be accompanied by the wearing assistance The listening time on the device is getting longer and better.”
