1. What is Praat?
Praat is a speech-analysis program designed by Paul Boersma and David Weenink at the University of Amsterdam. It is a freeware program and can be downloaded from the Internet ( http://www.fon.hum.uva.nl/praat/download_win.html ). See Figure 1.

2. What is Praat for?
Praat is a useful program to analyze speech. If offers a wide range of analyzing procedures, such as spectrographic analysis (e.g., pitch analysis, formant analysis, amplitude analysis, intensity analysis) and articulatory synthesis. In addition, a large amount of speech can be easily handled by using a script. Therefore, this program is helpful for phoneticians, speech pathologists, and general linguists.
3. How to use Praat.
When Praat is opened


9. How is fundamental frequency measured?
In order to measure fundamental frequency, click on the menu, Read, and then choose Read from file in the sub-categories in order to open a recorded file. See Figure 25.
Figure 25 . This Praat Objects window shows the recorded file extracted via Read.
In Figure 25, there are a variety of options on the right side. For example, click on Edit and the following window will appear. See Figure 26.
Figure 26 . Waveform of the selected file
On the top menu options of the given window, click on Pitch and on Show pitch in order for pitch analysis. A blue pitch contour will appear that represents the pitch of the selected file. See Figure 27.
