Accent (linguistics) - Non-native Accents

Non-native Accents

Pronunciation is the most difficult part of a non-native language to learn. Most individuals who speak a non-native language fluently speak it with an accent of their native tongue.

The most important factor in predicting the degree to which the accent will be noticeable (or strong) is the age at which the non-native language was learned. The critical period theory states that if learning takes place after the critical period (usually considered around puberty) for acquiring native-like pronunciation, an individual is unlikely to acquire a native-like accent. This theory, however, is quite controversial among researchers. Although many subscribe to some form of the critical period, they either place it earlier than puberty or consider it more of a critical “window,” which may vary from one individual to another and depend on factors other than age, such as length of residence, similarity of the non-native language to the native language, and the frequency with which both languages are used.

Nevertheless, children as young as 6 at the time of moving to another country often speak with a noticeable non-native accent as adults. There are also rare instances of individuals who are able to pass for native speakers even if they learned their non-native language in early adulthood. However, neurological constraints associated with brain development appear to limit most non-native speakers’ ability to sound native-like. Most researchers agree that for adults, acquiring a native-like accent in a non-native language is near impossible.
