Speaking is one of the most challenging English language skills for many TOEIC test takers to master. Even native speakers are often terrified when they first have to give a formal presentation to an audience: the fear of public speaking is in fact our most common phobia, with many saying that this fear is worse for them than even fear of death.
If you are preparing for TOEIC, however, giving a public speech is not what you have to master. You will be speaking privately and simply into the “ears” of a computer and being scored by expert raters who score international English anonymously and objectively, with no judgments based on accent or knowledge of who you are.
Speaking “to a computer” of course can generate its own fears (though in today’s VOIP- and DVC-connected business world you may be doing it every day). Fortunately there are many learner-friendly forums that will develop your skills and your confidence.
It’s amazing how many free, useful sites there are for teachers and learners of English. Or maybe not—successful teachers by nature love both to learn and to share their knowledge.
