“The Art of Memoir” by Mary Karr (post 3): Did “cobbling together a voice” mean assembling a group of voices, working together, under a single name?

If Mary Karr meant what the phrase “cobbling together” might imply, then her narrative voice might actually have been a group of voices, working in combination.

I compared the narrative voice to the host personality in multiple personality, and the host is usually one personality, but in some cases it is a group of personalities, working together and coordinating their efforts under a single name.
