People need to hear language to know how to speak

If a person was born 100 percent deaf they won’t know how to speak at all because they have never heard any words

If a person was born not fully deaf like but partially 40 percent, 60 percent of 70 percent they can still speak. Even though their hearing is not at 100 percent they still know how to speak because they have some hearing to know how to pronounce words.
