My throat was so dry/inflamed that I talked in a hoarse voice.
It´s not that cracked and inflamed would be the same thing, it´s there is an overlap of the said symptom (hoarse voice). And hoarse here is to be thought as the weakened voice, given the vocal strain. Not the grave voice (that can also be thought as hoarse).
Indeed it could be described with the two words "hoarse, thin voice", for example. Somehow croaky, raspy.
