Now that your script is completed, your teacher will assign roles and tasks (.docx 531kB). The largest speaking parts will be for the host and Charles Bean himself but you'll also need other voice actors. As well you will need a production crew of editors, students to choose appropriate music and background effects and to produce the end credits.
Audacity is one of dozens of audio editing applications that can be used to produce your This is Your Life—Charles Bean radio broadcast. Using your finished script, record all the speaking parts as individual audio files. The production crew will then put together all the audio files, add music and background effects and record a credits section at the end.
Congratulations on a great job!
