In English, it is usually the first vowel element that is more prominent, whereas the second one tends to be reduced. We can again distinguish between two different types:

Webspectrogram depends on the window-length used to calculate the spectra. • This is why in Praat, you use the same window length parameter to adjust both the bandwidth of spectrograms and the window length of FFTs. -standard window length for a spectrogram: .005s = 5ms -standard window length for a spectrum: .025 or .03s = 25 or 30ms 6.
