Praat scripts - In following Praat scripts, a wav file name is the same as a TextGrid file name. Furthermore, a wav file plus a TextGrid file is saved as a Collection file. Three files (a wav file, a TextGrid file and a Collection file) have the same name.

• Create table This script measures pitch, intensity and formants every 10ms.
• Duration and formants using LPC object This script measures duration and formants of a vowel. The being measured vowel is located in a interval of a tier. The location is defined by a user. Downsampled file is used.
• Duration and formants using Formant file This script measures duration and formants of a vowel. The being measured vowel is located in a interval of a tier. The location is defined by a user. This script uses the object of Formant.

The following scripts are useful for the project, "Developing a corpus of spoken language variability" (Lesley Carmichael, Richard Wright, Alicia B Wassink Nov 2003). The TextGrid consists of 9 tiers. The first tier and the second tier represent sentence-boundaries and word-boundaries respectively. The fourth tier shows darpabet. The seventh tier and the eighth tier represent style and Lombard respectively. The example of "style" is child-directed speech. The Lombard indicates whether the speech is taken place in a noisy environment or not. This script takes word-a long sound file plus a TextGrid.

• segmenting speech This script segments a long wav file based on the intervals in TextGrid. This produces Collection files (wav files plus TextGrid fiels).
• segmenting speech2 This script does the same as the previous scrit. However, if an interval contains no text, this script does not create a Collection file.
• Short interval checker This script checks whether or not the duration of an interval is less than 1ms, and creates an Excel file.
• word duration and MLU This script calculates the average of word duration and MLU.
• vowel duration, pitch, intensity and formants for PC This script provides an EXCEL file, which has vowel duration, pitch, intensity and formants
• vowel duration, pitch, intensity and formants for Mac This script should be place in the same directory of Collection files
