Of course! The telephone is a wonderful tool for language-learning. First of all, you are naturally in a state of full concentration. With oral communication you have to focus on what you hear. There is no body language which usually conveys a large part of the message.
Secondly, on the telephone, you don’t have any choice – you have to speak!! Gestures are useless and this forces you to find other means of communication using words, either those locked away in your passive memory, or newly acquired. The barriers (fear, mental blocks, etc.), often present when you have to speak in a foreign language, are quickly overcome.
In addition, you don’t need to leave your desk, reserve a meeting room for group lessons etc. Therefore, no time is wasted. What could be simpler? A fixed line number and/or the internet, and you’re off!
Finally, one to three 30- minute lessons per week, on average, are easy to accommodate, even in a busy schedule.
So what are you waiting for to try?
