![]() ![]() If your sound is long, you may have to zoom in in order to see the separate pulses. If you do not see these lines, choose Show pulsesfrom the Pulsesmenu. The Praat program was created by Paul Boersma and David Weenink of the Institute of Phonetics Sciences of the University of Amsterdam. Most of Praat's voice analysis methods start from the glottal pulses that are visible in the SoundEditorwindow as blue vertical lines through the waveform. Voice analysis (jitter, shimmer, noise): Voice.Creating the pulses in the Objects window The pulses you see as blue lines are a PointProcessobject. This page tells you how to do that for voice analysis. Instead, you probably want to work with objects in the Objects window only. There are also more specialized tutorials: In a Praat script you usually do not want to raise a Sound window. Manipulation: of pitch, duration, intensity, formants. Compare the pitch and timbre of your selections. Try playing individual peaks or groups of peaks. You should see a spectrum showing the component frequencies for the waveform. Intensity contours: view, configure, query, the Intensity object. Load one of the square waves, select a section from the middle of the waveform about 1 second in length, and generate a spectral slice of this portion. It offers a wide range of standard and non-standard procedures, including spectrographic analysis, articulatory synthesis, and neural networks. Pitch contours: view, configure, query, print, the Pitch object.įormant contours: view, configure, query, the Formant object. PRAAT is a very flexible tool to do speech analysis. Spectral slices: view, configure, the Spectrum object. Spectrograms: view, configure, query, print, the Spectrogram object. We studied a total of 99 voice samples from individuals with Reinke's oedema. In fact, the Praat software (Boersma and Weenink, 2009) can calculate five different measures of jitter and six different measures of shimmer. How to get a sound: record, read, formula. Voice acoustic parameters (jitter, shimmer, harmonics-to-noise ratio, fundamental frequency) (quantitative).
