The Speaking section of TOEFL iBT involves recording spoken responses to questions. TOEFL PBT includes face-to-face oral interviews.
In the TOEFL iBT Speaking section, test takers are required to orally respond to a series of prompts or questions using a computer microphone. They are presented with various tasks such as expressing an opinion, summarizing information, and providing solutions to problems. Each response is recorded and sent to ETS for evaluation.
On the other hand, the Speaking section of the TOEFL PBT (Paper-Based Test) involves a face-to-face oral interview with an examiner. Test takers are given similar tasks as in the iBT, but they respond directly to the examiner instead of recording their responses on a computer. The examiner evaluates their spoken English proficiency based on factors such as pronunciation, fluency, grammar, vocabulary, and coherence.
