Medicine, Oral Dynamics Lab (ODL)
A. Introduction
This tutorial provides an introduction to some of the basic procedures in the program
PRAAT. This is a freeware program for the analysis and reconstruction of acoustic
speech signals. The software can be downloaded from the following website:
http://www.fon.hum.uva.nl/praat/. This page also includes a PRAAT beginner’s manual
written by Sidney Wood. PRAAT can be used on different operating systems (see
PRAAT website for more information), but this tutorial is based on Windows 2000 OS.
PRAAT is a very flexible tool to do speech analysis. It offers a wide range of standard
and non-standard procedures, including spectrographic analysis, articulatory synthesis,
and neural networks. This tutorial specifically targets clinicians in the field of
communication disorders who want to learn more about the use of PRAAT as part of an
acoustic evaluation of speech and voice samples. The following topics will be covered:
1. Finding information in the Manual
2. Create a speech object
3. Process a signal
4. Label a waveform
5. General analysis (waveform, intensity, sonogram, pitch, duration)
6. Spectrographic analysis
7. Intensity analysis
8. P
