How do you find the LPC coefficient in Matlab?

[ a , g ] = lpc( x , p ) finds the coefficients of a p th-order linear predictor, an FIR filter that predicts the current value of the real-valued time series x based on past samples. The function also returns g , the variance of the prediction error.

What does F2 formant mean?

F2: The second formant (F2) in vowels is somewhat related to degree of backness, i.e. the more front the vowel, the higher the second formant (but affected by lip-rounding).
