The name of the file you select, here KAB_AM_NARR_03.wav, will appear on the list of

“Objects”.

You select it (click on it) and choose from the menu to the right.

3.2.1. Opening an audio sound-file in Praat

File, Read from file: this takes a lot of the computer’s memory, and may slow down

applications. Editing is possible.

File, Open long sound file: this draws less on the computer’s memory. Any editing is

possible.

3.2.2. Creating a Mono object from a stereo one

Convert, Convert to mono

3.2.3. Saving an audio file

Write, Write to .wav file

We must have a sound file in Praat that corresponds exactly to what we want in the final

stage. Do all the changes (noises at the beginning, etc.) in Praat at the very beginning of

the procedure (edit, etc). Then save your file as .wav.

Start with a short blank (< 70 ms) so that it's easier to listen to. Do that BEFORE any

transcription in Praat.

3.2.4. Cutting the sound file into a new file / Editing a file

If you wish to cut a sound file into a smaller file you must first “Edit” the original file you

recorded, which you named for instance “Tale of the seven girls.wav”. It appears in the

window called “Sound”. You select the part you wish to cut by clicking-dragging the

mouse on the part you need, and then you choose in the menu “File” of this window,

“extract selected sound (time from 0)”. The sound appears in the window “Praat objects”.

You must rename it (using the option “rename” below the list of Praat objects), for

instance: KAB_AM_NARR_04.wav.

It can be easier to cut files using another device (Audacity, or SoundForge for example)

before opening them in Praat. Praat is more useful if you want to cut the sound into

smaller chunks, for analytical purposes for instance.

If the file is fine as it is, you may want first to just play the sound, or have a look at F0 or

Intensity values. In that case, click on “edit” in the “Praat objects” window, and click on

the “visible part” below your Sound window.
