A window opens, with multiple lines; from the top:

• a line showing the signal in black (you won’t use it much);

• a line containing a blue and a green line (if the commands 'show pitch' and 'show

intensity' have been activated); they are the pitch and the intensity lines,

respectively; do not worry if the blue line is not beautiful — e.g., if it is not

continuous and looks flat: we’ll try to have it look nicer in a second;

• a yellow line: it will contain your transcription:

What if you are not happy with your blue line?

You may try to correct this by changing the values of the pitch.

To do this you look at the top of your window: you go to the menu

• Pitch

and select

• Pitch settings

Which values are to be chosen? The values will change from speaker to speaker,

especially according to gender and age. They may also change in the course of the

recording. Therefore, adjustments are to be made.

For adult males, it is better to choose low values, such as 15, or 30, or 50 as low value,

and 200, or 300 as high value.

For females better values range from 50 to 500, sometimes higher.

In general, do not trust Praat if the blue line (the pitch) shows sudden and very sharp

(vertical or almost so) changes. Try changing the pitch settings in that case.

You can start working on the transcription:

You can select a part of the window by clicking and dragging with the mouse and then

clicking on “sel” (for “select”) on the lower left-hand part of the window.

You can always revert to the whole picture by clicking on “all”.

You can make as many selections as you want.

3.2.7. Creating the boundaries of the prosodic units

Begin with segment delimitation while using the spectrograms as well as the wave-form

for boundary indication.
