Description: This script measures Pitch (Fundamental Frequency or F0), the standard deviation thereof, jitter, shimmer, and harmonics to noise ratio (HNR). The analysis parameters are set for human female voices as a default, so if you need to run this on human males, make sure you replace the pitch floor to 60 Hz or 75 Hz, depending how low you sample goes, and the pitch ceiling with 300 Hz. I use 60 especially when I've manipulated pitch to be close to 80 Hz because it needs some breathing room. Remember if you're measuring a central tendancy of pitch, that individual values could be quite low. Leave some space, but not too much space. The script will measure the aforementioned acoustic characteristics on all of the wav files in a directory (not subdirectories). The script will ask you for a path. Make sure you put a slash at the end of the path. Don't put spaces in your filenames. Get Praat at http://www.praat.org
