What is one of the purposes of this speech?

Welcome, everybody. I’m here to talk about our telephone helpline. The helpline is a free service for anyone who needs help with looking after a child. We have hundreds of trained volunteers. Our operators lend support to over 400,000 parents and families each year by providing information for anyone in a parenting role. We’re always looking for additional helpline operators and new volunteers are always welcome. So how does one go about becoming a volunteer? Well, it’s really quite simple. After an interview, all volunteers will take a ten-week training course. Upon successfully completing this course, volunteers will be asked to go to a particular call center. It is necessary for volunteers to be a-ble and willing to visit their call centers at least once a week. Volunteers are expected to give a minimum of four hours of their time a week dealing with calls. Currently, there are two call centers operating in London and another half a dozen centers in other places of England. Well,  that’s all I wanted to say. If you have any other questions, please don’t hesitate to ask me. And for any of you who are seriously considering becoming volunteers, there are application forms on the table in front of the stage.
