do what other games do then, use a proper title. ie Adventurer would fit in 80% of cutscenes in place of our name; keep our name in text, but spoken would be adventurer. Friend/companion could also be used in most. between the three, I doubt there are many cutscenes that would be forced to just skip it altogether where it would be like "Thank you for getting here so promptly, (name)." and you just would hear the first.
