![]() ![]() Wideband slices show the formant structure at the selected time location, narrowband slices show more detailed spectral structure (which will be the voice harmonics if you are examining a voiced segment).The Dynamic range for the slice is set independently of the spectrogram from the View menu in the slice’s own Spectrum window, its effect there being to expand or shrink the dB range of the visible sound pressure scale. Dynamic range in the Spectrogram settings dialog is also uniquely for the spectrogram, hiding or showing background noise.Once you see the slice in its own own Spectrum window, you can modify the visible frequency range by using the zoom settings in the View menu there. The frequency range of the slice is always that of the signal being analysed, i.e.Set this range to to show the detail you want to see there. Note that the View range is only for the spectrogram.To restore the default settings, click Standards.Make any adjustments you need (the parameters are explained as they arise below). The following dialog appears, showing your current settings. To check the settings, open the Spectrum menu in the Sound editor and select Spectrogram settings.If you change that setting now for the slice, the spectrogram will be similarly modified too. ![]() The Window length setting for spectral slices is the same as for the spectrogram.Better still, open the View menu and select Show analyses, where you can show the spectrogram and hide any other analyses that happen to be open, all in one place:.If the spectrogram is not already visible, open the Spectrum menu and tick Show spectrogram:. ![]() It is extremely helpful to have a spectrogram on view, to help you find your way about in the speech signal, follow the formant movements, and find the precise location for the spectral slice.The Sound editor opens, showing the waveform of your signal along with any analyses that you had used on the previous occasion you had the Sound editor open ( Praat remembers your analysis selections from one session to the next). Load your signal into the Objects list, select it and click View&Edit.The second is a Swedish adult female speaker saying ett forskningsprojekt.The first is a Swedish adult male speaker saying finns det dokumentära inslag.A male and a female speaker are used to illustrate the procedure.The speech examples used as illustrations The initial setup is the same for both procedures – having a signal to work on, understanding the parameter settings, deciding where to make the slice etc. ![]() This Beginner’s manual describes the Sound editor procedure.
