NORM Praat Script README

Praat script for measuring vowel formants for NORM processing.


Before you use this script, you must edit the settings in the next section.

The script will not function at all if you do not specify a speaker. Do not use spaces or other special characters in the name of the speaker.

If you would like the output file to be put somewhere other than the current directory, specify that in the filepath, relative to this file.

How To Use This Script

  1. In Praat, load the script into "Log script 3" or "Log script 4" by entering the full path of the script into the menu accessed by executing [ Query > Log settings... ].

  2. To measure monophthongs, put the cursor at the desired point or select an entire segment to get the mean measurements over that range.

  3. To measure diphthongs, you will have to run the script twice. For the first run, select the initial steady-state position as if it were a monophthong. For the second run, select the glide position.

  4. To run the script, execute [ Query > Log script 3 ] or [ Query > Log script 4 ], depending on what you did in Step 1.

  5. In the first menu, specify the word you are measuring and a unique way to refer to the vowel you are measuring. (The same vowel should always have the same name.) You can use any system you want, as long as you are consistent. Click OK when you are done.

  6. The next menu will ask whether you are measuring a monophthong or a diphthong. Give an honest answer.

  7. On the second run of a diphthong measurement, the information you enter in the first menu is discarded, so you can leave it blank.

  8. If you have measured the initial position of a diphthong, but not its glide position, Step 6 above will be different. Instead, it will ask you whether you want to measure that glide position or pretend that you had measured a monophthong and just move on to a new measurement. Again, be honest.

  9. Once you have completed these steps once, a file will appear with the name of your speaker and the file extension '.tsv' (for tab-separated file). When you have completed your measurements, you can feed this file into NORM and have it plot all your vowels.
