select any of the characters on screen, remix the project, and say these lines for the character: "Hello." "How are you?" "What are you doing?" "That's awesome." you can record other lines, but you need to, at the minimum, record the lines above, also, so I know which character you're auditioning for, only show that character and hide all the others. once you've recorded and put the lines into the remix for the collab, share it and I will review the entry's and determine which one is best.
as you can see, I put equal male and female characters. I'll do some voice acting too. EDIT: You need to record your real voice, text-to-speech is not allowed! EDIT 2: Do not modify the characters, if think it's a good idea for character design to look different (e.g different colored clothes), submit the modified design by remixing the other ideas project.
