The accent used in a foreign language is just as important as grammar and vocabulary. This is especially true for tonal languages. One wrong pronunciation can modify the entire tone and message of a sentence. While it is not important to be too strict on the accent, it is still something to keep in mind. After all, the essence of language is communication. A terrible accent can be a barrier to effective discourse. Aside from the previous methods mentioned, a learner can also observe how natives speak.
A learner can observe the placement of their tongue or shape of their mouths as they speak. This is especially useful for languages like Korean. The placement of the tongue inspired the characters used in the Korean alphabet known as Hangeul. The learner should also take note of the various intonations that a native speaker uses in different settings. When they are formal, speaking to their friends, angry, or happy. These help in ensuring that speaking comes out as natural as possible.
