Identifying sounds in spectrograms Let's look at how various kinds of sounds appear on a spectrogram. Vowels 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: 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 … 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, and on a spectrogram it … 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 formants. But the acoustic properties of tubes with branches and side-chambers … See more The medial phase of a voiceless plosive is complete silence.
