Hi everybody
I have a big problem, maybe a little bit strange. My English is good and I can hold conversation in face to face but when I need to speak on the phone I am terrible. I am afraid from I won't understand what they want say to me. I feel so stupid. What can I do with it? How can I practice? Is it a common trouble or unique?
Dave put it rightly. There is a possibility of misunderstanding during audio conversations as the expressions and gestures are not visible.
Listening to audio conversation of others can help you to an extent but the most important is to practice your own conversation. You might request the other person to speak little slowly and you too can take pauses while speaking. Practicing more and more is the only way to go! All the best!
