Human speech is governed by the cranial nerves and the brain. The only cord or nerve function that assists speech outside the skull is the phrenic nerve (C3-5) which make the diaphragm move. Without the phrenic nerve, there is no chance of life (without a ventilator).
You may have a “subluxation” of C1-2 as noted by your chiropractor but this will not affect speech function. Manipulation may help you but the neurology described to you is incorrect.
