5 Speech Functions Behind a High TOEFL Speaking Score

Many students preparing for the TOEFL test focus heavily on vocabulary, pronunciation, and grammar. While these skills are important, high-scoring candidates in the TOEFL Speaking section also demonstrate something equally valuable: the ability to use different speech functions effectively.

Speech functions are the ways we use language to communicate ideas, opinions, explanations, and solutions. In the Speaking Section of the TOEFL test, examiners evaluate not only what you say but also how effectively you communicate your message.

Understanding these speech functions can significantly improve your TOEFL Preparation and help you respond more naturally and confidently during the exam.
