iOS app creation

I want an iOS app created. It will require very simple speech identification (one of three different consonant and vowel sounds detected) and show an image and text of one of three answers for the user. (Hungry, Tired, Burp) This will be depending on what was said, will show an image and txt. It will detect the main sound in a babies cry and then tell the user what the baby wants. Is the baby Hungry, Tired, or need to be Burped? ** This will be an accurate app, not a prank app as there are three base consonants and vowel sound combinations that babys say in their crying. (Although the possibility of a prank app as well is possible. i.e baby wants a beer!)
