Unity3d + IBM Watson + Google Cardboard Q&A system

I need a question and answer system using ibm watson for google cardboard using Unity2018.3.6f1. I want to play an audio clip to ask the user a question and then I want to be able to get feedback of the users spoken response to be able to tell if it is correct answer or not. Workflow-- 1) Play audio clip of a question 2) Listen for user response 3) If the users response is correct, play a "good job!" audio clip, else if user says the wrong answer, play a different "wrong answer" clip In the unity inspector window, I want to be able to drag and drop in the audio clip question, type the expected response string, and drag and drop in a correct and incorrect response audio clip. Example-- 1) **audio plays question to user** "What color is an apple?" *User spoken response* "Red" **Correct audio response clip is played**"That's right!" 2) **audio plays question to user** "What color is this book?" *User spoken response* "purple" **Incorrect audio response clip is played** "Sorry try again!"
