Hi Melinda,
You may just need formula field using a concatenate formula, which would be something like:
concatenate({Speaker 1 - Name},", ",{Speaker 2 - Name},", ",{Speaker 3 - Name})
The field names are in curly brackets {} and then I've added ", " to add a comma and space between each speaker.
Do the same for the email fields.
When you create a linked record in your other table, you can then add a lookup to these new formula fields.
I hope that helps!
