May 16, Current Version - 5. May 16, Disclaimer: This script package, although in production use by the authors and others at the CU Phonetics Lab, the University of Michigan, UC San Diego, and elsewhere, may still have bugs and quirks, alongside the difficulties and provisos which are described throughout the documentation.
By using this script, you acknowledge: That you understand that this script package does not reliably produce camera-ready data, and that all results must be hand-checked for sanity's sake. Thanks for using our script, and we hope it works wonderfully for you!
A Warning on Nasality Data This script has provided meaningful data, used in a variety of publications in our lab, and externally. Please see my JASA paper for a more up-to-date survey of some of the problems inherent in acoustical measurement of nasality. About the Script This script measures a variety of nasality-related values at multiple points, in vowels marked in a TextGrid annotated sound. Input This script uses sound files with associated TextGrids TextGrids should have at least interval 2 tiers: one for vowels and one for words.
Relevant and word vowel intervals must be labeled. As currently written, each word must contain exactly 1 vowel interval. Important Note! Output A log file. Process: The script looks for soundfiles with a specified extension in a specified folder. If not, the user can manually enter the requested vales in a pause form.
Accompanying Files NasalityAutomeasure. Installation: This script package doesn't really need to be installed, just drag the whole folder to a safe place on your computer. Data format: Your data will need to be in soundfile.
Modes of Running: There are three ways to run this script, in two-pass automation mode, manual mode, or full-auto. How does this script work? Simply put, for each timepoint, the script will: Extract the pulse nearest to the timepoint Copy that small pulse over and over again until it reaches 0. Unless you're sure it applies for this speaker, do not use this value.
This number is the result of that method, based on the HighPeak A1-P0. This number is the result of that method, based on the A1-P1 above a3p0 - The amplitude of F3 - the amplitude of P0. Fundamentally, a measure of spectral tilt See Styler An entry here doesn't mean there's a problem with the final data. Any measurement which shows something other than "none" listed here should be excluded from further use or analysis. This means you'll have to try another point.
Troubleshooting and FAQ "Oh no! Remember, settings in the startup dialog aren't saved, so you'll need to re-enter each time. If you've run the script before on this set of data, and the script won't re-measure, just delete the nasprogress. The script crashed while processing! This usually happens because a given word doesn't have any modal voicing, and as such, the script can't get a handle on it. There will be some files that can't be measured by this technique, especially those with heavy creak, and you'll just have to give up on those.
I'm being asked to verify this spectrum and it's all wrong! Just put the cursor on a point and run the script. Your best bet is the blackest part of a pulse, in a region where Praat has a pitch-track. If you can't get a good spectrum anywhere in the word which does happen , delete that word from the to-measure folder and move on with life. If your top line in the verify window is "ERROR: Manual Measurement will be needed, 0 inserted", there's no pitch track or the script tried to crash.

Don't worry, and proceed as usual, you just won't have data for that. Something's wrong with my data! This is expected behavior, and is a limitation of the ability of Praat to resolve frequencies in small samples. The amplitude measurement which is what A1-P0 cares about anyways is still reasonably accurate despite this.

If you see Zeroes or "-- something --" in the data log, just erase them, because of a lack of pitch-track, data for that point was unable to be measured. My poor computer has been brought to its knees! Praat is frozen, my fans are going crazy, and it's been chugging for almost 20 minutes! If this is a source of major pain for you, you can purposefully slow the script down by removing "noprogress" in the line around line , at the time of writing : noprogress To Pitch Version History Version 2.
