When I was looking for a teacher who can speak fluently with good voice and clear pronunciation, a friend told me the name of Teacher Hans.
He has a charming personality and can dig into the details of everything that I say. As a result he can increase my talking time, so I can enjoy each talk with him.
Recently, I started "TOEIC Speaking" course. In those lessons, he recorded his reading of the subject for my self-training.
While listening to them, I'm inspired by the desire to speak fluently like him.
I think I'm in the intermediate range but I can recommend his lesson for beginner to advanced students.
