Now let's discuss how we analyze tone using Praat. We will use a recording of the four Mandarin words as an example.
- Created a wav file with four Chinese words mā "mother", má "hemp", mǎ "horse", and mà "scold"
- Selected the file and click "View& Edit"
- "Pitch" → tick "Show pitch"
The window is like this:
Figure 1
This window provides us with a graphic presentation of the variation in fundamental frequency (pitch contours) of the four Mandarin tones.
- Adjust the pitch settings to make the display clearer.
I just brief two important points here:
- First, adjust the range of analysis as men have pitch ranges in the 50-180 Hz range while women's pitch tends to be higher, 80-250 Hz.
- Second, autocorrelation is preferred for intonation studies and cross-correlation for tone studies.

- Draw the pitch contours
- Select an area in Picture window using the pink frame
- Select "Pitch" → "draw visible pitch contour"
- See the results in Praat picture window
