Self-correction is vital in being able to speak a language fluently, especially if the learner is self studying rather than taking part in group classes. By listening to one's self, the individual is able to focus on the production of sounds and tones that they need to improve or correct. This method comes in handy when a person is learning tonal languages, such as Mandarin Chinese or Thai. These languages are reliant on the use of pitch in language to distinguish different meanings of words.
Thus, practice and self-correction are vital in being able to speak these kinds of languages. One trick to adopting this method into a learner's study habits is to mimic native speakers. The learner can get a hold of audio recordings of native fluent speakers with which they can compare their recordings to. This method is effective as it is a convenient and cheap way to improve one's speaking skills.
