WebFig. 4. Wide-band spectrogram of the word ‘heard’; vertical striations show individual voicing pulses Narrow-band spectrograms (Fig. 5) pick individual harmonic that appear as black horizontal lines, and the drops of energy between successive harmonics that appear as white horizontal lines, but temporal resolution is poor. WebA spectrogram analyses a speechwave into its frequency components. This allows us to see more detail about the articulation of the sounds. A spectrogram is rather like a graph. …

WebA Course in Phonetics. Chapter 8 - Exercise 8K. Which number in the spectrogram corresponds to the sound? Weba. Oral stops. For the oral stop samples provided below, as well as the spectrogram, there is an FFT/LPC spectrum of the stop burst for all stops, an FFT/LPC spectrum of the stop aspiration for the voiceless stops and an FFT/LPC spectrum of the stop occlusion of the voiced stops. Like many stop bursts, the spectrum of this burst is quite flat ...
On a spectrogram, it looks a little like a cross between a fricative and a vowel. It will have a lot of random noise that looks like static, but through the static you can usually see the faint bands of the voiceless vowel's formants. Plosives The medial phase of a voiceless plosive is complete silence. See more Vowels usually have very clearly defined formant bars, as in the following: In dipthongs, you can see the formants change frequency as the tongue body moves through the mouth: You can't always tell reliably … See more Fricatives are easy. The turbulent airstream of fricatives creates a chaotic mix of random frequencies, each lasting for a very brief time. The result sounds much like static noise, … See more Nasals and [l]usually look like quite faint vowels, without a lot of amplitude in the higher frequencies. You can still see some things that look like … See more The medial phase of a voiceless plosive is complete silence. On a spectrogram, this will appear as a white blank. The quiet vocal fold vibrations in a voiced plosive will sometimes appear as a faint band along the bottom of … See more
