Pitch-Detection (warm-up project!)

Implementation of Pitch Detection algorithms with Matlab

I recorded the sentence "امروز هوا روشن و آفتابی است" in Persian (you can record any sentence in your language!). And tried to estimate pitch with three different methods.

1: speech pitch detection with the short-time autocorrelation function

    5 pitch candidates have been considered in each frame 
    run main(1).m to see results

autocorrelation result

2: speech pitch detection with average magnitude difference function (short-time amdf)

5 pitch candidates have been considered in each frame
run main(2).m to see results

amdf result

3: speech pitch detection with real cepstrum analysis

5 pitch candidates have been considered in each frame
run main(3).m to see results

real cepstrum result
