![]() The “advanced” pitch settings like Silence threshold and Octave jump cost can stay at their standard values. You may also want to choose Optimize for voice analysis otherwise, the voice report will complain about possible inaccuracies. 50–200 Hertz for pathological male voices if that is the typical range. The standard range is 75–600 Hertz, but take a range of e.g. In general, you will want to be careful about the pitch range. The results of the voice measurements will depend on your Pitch settings. The Pulse menu contains the command Voice report, which will show in the Info window the results of many voice measurements for the visible part of the selection (or for the visible part of the whole sound, if there is a cursor instead of a selection or if the selection is not visible). The measurement results will also vary slightly when you zoom or scroll. This is because only the visible part of the sound is used for the analysis. Here is the code: Read from file: 'sound.wav' selectObject: 'Sound sound' Select: 0.108, 0.112 Extract selected sound (preserve times. It offers a wide range of standard and non-standard procedures, including spectrographic analysis, articulatory synthesis, and neural networks. This part of the sound is always between 0.108 s and 0.112 s because it is from pure tones. PRAAT is a very flexible tool to do speech analysis. You may notice that for some sounds, the time location of the pulses can vary when you zoom or scroll. In Praat, I want to select a portion of the sound, extract it, and save it separately from the original file. It was designed, and continues to be developed, by Paul Boersma. If your sound is long, you may have to zoom in in order to see the separate pulses. This book is about Praat, a free computer software package for speech analysis in phonetics. If you do not see these lines, choose Show pulses from the Pulses menu. Most of Praat's voice analysis methods start from the glottal pulses that are visible in the SoundEditor window as blue vertical lines through the waveform. To understand this tutorial, you have to be familiar with the Intro, which describes the more general features of the SoundEditor window. ![]() This tutorial describes how you can do voice analysis with Praat.
