1. Specific words Recognition, using MATLAB

A. Pre-emphasis:

	1. smoothing filter

	2. remove silence

B. Hamming Window

C. Feature Extraction

	1. pitch
		split Voice and Unvoice
		(we use Voice Only)
	2. MFCC
		13 first MFCC coefficient

D. Training

	1. standardize
	2. KNN algorithm
	
	use makeNewClassifier.m

E. Test

	use CheckAudio.m

---

2. Open/Close door-lock with Arduino

	use CheckAudioA.m
