Interview in phone.

Today I get a phone from some company HR.The HR is a girl whose voice is nice.

Firstly she introduces herself and her company to me.But in my office,I feel nervouse and can't get her words clearly.

Then she asks me to introduce myself. in English I know the interview in phone is beginning. To be honest, interview in phone is my weakness. Always I can't express myself well in English. Though I have some experience in interiview in phone. When I begin speak English in phone, I am stuttering. I just speak two sentences and she breaks me.She says in her nice voice.It is ok and I just want to know your pronunciation. I strongly understand my pronunciation is not good. I feel  I will lost an opportunity again.

Of course  I am not afraid. I have a job now.But I know I have to improve my oral English.
