Speed-dating with the program Praat … exercises with some basic functions of the program Praat.
Praat (www.praat.org) is an incredibly useful computer program that you can use to record, save, edit and analyze acoustic voice and speech signals in the clinic. Next to for example speech synthesis, it also offers ways to draw numerical and graphical information on these signals.
To introduce you to the basic functions of Praat, to let you take some initial steps in this program, and to already have basic skills that simplify the use of Phonanium’s scripts/plugins, you are advised to do the exercises below. Please follow all steps in the exercises.
- Record sound, and rename, save and re-open objects
> Click here - Copy, listen to, downsample and re-listen to a sound object
> Click here - View a recording of a sustained vowel, analyze its medial 1 second on various voice characterstics, and extract this portion
> Click here - Analyzing sound objects: fO
> Click here - Analyzing sound objects: intensity
> Click here - Creating and analyzing a long-term average spectrum (LTAS)
> Click here - Create and inspect a narrowband and a broadband spectrogram
> Click here - Create and analyze a cepstrogram and a cepstrum
> Click here - Drawing graphs and analyses
> Click here - Erasing the Praat Picture window, adding data to graphs and copy/paste drawings
> Click here - Repetition
