Peaks in intensity (dB) that are preceded and followed by dips in intensity are. Another interesting possibility is creating artificial sounds (e.g. Normative Values for PRAAT in the Age Range of 5-10 Years 351 Old Typically Developing Children vowel sounds helps us to understand the fundamental frequency (fo), intensity, and the filter characteristics (formant frequencies, jitter, shimmer, etc.). A script written in the software program Praat (Boersma & Weenink. PRAAT is a very flexible tool to do acoustic analysis. The DFTs are averaged using time-averaging (Shadle 2012). PRAAT can be used on different operating systems (see PRAAT website for more information), but this tutorial is based on MacOS Sierra (10.12.3). Furthermore, so called TextGrid-Objects can be created in order to transcribe and annotate sound objects. Spectral moments of fricative spectra script in Praat which extracts the first four spectral moments (center of gravity, standard deviation, skewness, and kurtosis) as well as the global intensity and duration for each fricative. Praat offers the possibility to record mono and stereo sounds and to edit and analyse sounds regarding intensity, pitch height, duration or formants. General analysis (waveform, intensity, sonogram, pitch, duration). The software is constantly updated and so are the tutorials that are offered first of all for beginners but also for experts who have questions on specific topics. Measurements Get intensity, duration, & mean f0 over 12 points of the vowel (Adapted from Christian DiCanio) Get duration measurements for each annotated word. PRAAT website for more information), but this tutorial is based on Windows 2000 OS. If that does not help, use the Search button in Praat’s manual window. Make sure you have read the Intro from Praat’s Help menu. It works for every common operating system. Many problems can be solved by upgrading to version 6.3.14 of Praat.
