| Topic-187: Measuring the Fundamental Frequency Fundamental frequency (For Pitch) is an important component of source-filter theory. It can betaken from the middle of the sound (e.g., vowel) using three techniques including displaying the Pitch track (automatically, measuring from Pitch track manually, and by looking at the waveform – by highlighting one cycle. Before measuring the fundamental frequency, we need to have a recorded file containing a vowel sound (e.g., [æ]). Let’s learn all of the three methods one by one 1. Displaying the pitch track and allowing Praat to measure the pitch automatically • Display the pitch track Pitch > Show pitch. • Place your cursor in the middle – a stable portion of the vowel. • Go to Pitch > Get pitch – a box will appear with the pitch value in it (note it down) 2. Displaying the pitch track and measuring pitch manually • Display the pitch track - Pitch > Show pitch. • Click on the blue pitch track in the middle of the vowel. • A red horizontal bar should appear with the pitch value (in dark blue) on the right side of the window (take the measurement from here. 3. By looking at the waveform (top of the display Copyright Virtual University of Pakistan Phonetics and Phonology (ENG) VU • Zoom into a small piece of the waveform in the middle of the vowel and measure the period by highlighting one complete cycle and noting the time associated with it (in the panel above the waveform).
