The spectrum of the burst is exactly the same as the spectrum of the corresponding fricative. Other times they're in the same place, as in "tsa" and "dza"). Sometimes the frication is a centimeter posterior to the stop, as in English "cha" and "ja", or German "pfa". Usually the frication needs to be at least 50ms for it to be heard as an affricate. (an affricate is just a stop consonant with an extra-long fricative burst. Sometimes the tongue is held there so long that you would call it an affricate instead of a stop. In beatboxing, though, the speaker holds the tongue in position to get a longer fricative burst. In normal speech, this fricative transient disappears very quickly, because the speaker is done with the stop and is now trying to say the vowel. Let's just look at the first part, and identify a few of the stop bursts.įor the first 5-10ms after release, the tongue constriction is still tight enough to generate turbulence right there at the constriction. Maybe he's just electronically edited two performances together, but if this is a real-time performance, it demonstrates really impressive articulatory control. In the first 1.5 seconds shown below, he vocalizes an /ŋ/ while simultaneously generating three more /t/ burst. This basic stop transients are all there, but this artist uses a nasal /m/ to give his bass drum a less muffled effect he uses a /ts/ to give a more resonant high hat, and a simple /s/ to create a high-hat swish. The transient of a /p/ sounds rather like a muffled bass (no front cavity resonance), /k/ sounds rather like a snare (front cavity resonance at around 2000Hz), /t/ sounds rather like a high hat (front cavity resonance at around 4000Hz). "Beatboxing" is a musical art form, in which phonetic transients are produced in a way that imitates the sound of a drum set. ![]()
