I need some people to help me with my voice (the voice as in sound prodiced by the vocal cords)

I'm applying for a callcenter/collective agent position and I would really appreciate it if any of you could help me. Here's my YM name :eric_jca09. Just leave a message so we could set a time to chat or something. I need your feedback regarding my voice. Rubah said I should try this.

Note: I do not own a webcam sorry.
