- English: In the United States, the Dictionary of American English is considered the standard, while in the United Kingdom, the Oxford English Dictionary is the go-to resource.
- Spanish: Two main standardized variants of pronunciation exist: Latin American Spanish (based mainly on the pronunciation of the educated people of Mexico City) and Iberian Spanish (based mainly on the pronunciation of the educated people of Madrid and other central regions of Spain).
- French: Academie Francaise is the governing body that oversees the French language and its pronunciation. They publish the official French dictionary and issue guidance on pronunciation changes.
- Mandarin Chinese: The standard pronunciation is based on the standard accent of Mandarin spoken in Beijing. The Ministry of Education of the People's Republic of China is the official body responsible for determining and maintaining the pronunciation of Mandarin.
These bodies work with linguists, scholars, and language experts to ensure that pronunciations are accurate and consistent. They consider various factors such as historical usage, regional variations, and the evolution of the language.
