Campto Voice Call Change

It seems camptos vocals have changed and Im not sure if its intentional/alluding to the next tlc, but I found it odd.
Adult camptos generic/chat call sounds like baby camptos heart call (or somewhat baby-ish) which also makes baby camptos call very high pitched.

Just odd sounding, like I said. And makes baby campto very high pitched

That it was not supposed to be changed, if at all or not yet. (or if it was, Im not sure)
