Accent reduction, also called Standard American English pronunciation training, accent neutralization, or accent modification, is a systematic approach to reducing or changing a person’s accent. This is achieved by learning how to pronounce the sounds (consonants and vowels) and the stress, rhythm, and intonation of Standard American English.
Everyone learns the sound system of their native language. A person’s accent is created when they learn a new language and combine the sounds of the second language with their native language. An accent is the “unique way that speech is pronounced by a group of people speaking the same language”, according to the American Speech-Language-Hearing Association.
