The ex-Wales captain, 36, has expressed an interest in a managerial future and - having completed his Uefa A coaching licence - this is a first step.
"I'm not sure if I want to be a coach or a manager, so I've agreed to this part-time role to dip my toe in the water," Speed told the Wales on Sunday.
"It's only one night a week and I live in Chester so it's not far for me to travel, I've got some ideas to try."
