Brief Summary

Beatboxing is a form of vocal percussion primarily involving the art of mimicking drum machines, using one's mouth, lips, tongue, and voice. It may also involve vocal imitation of turntablism, and other musical instruments. To produces the different sounds, the Beatboxers use their vocal apparatus in a much wider and more complex way than its use in speech. This allows them to acquire a panel of rich and varied sounds. The Human Beatbox (HBB) is a very recent subject of study in phonetics. This study offers an exploratory study of pharyngolaryngeal articulatory behaviors using nasofibroscopy and electroglottography and an aerodynamic study in order to better understand the articulatory capacities and limits of the vocal tract.

Study Arms (2)

Professional beatboxer singer

OTHER

1 professional beatboxer singer will be asked to produced different sounds while undergoing the different procedures. Researchers wil then select the most interesting sounds to be studied.

Other: Nasofibroscopy; Other: Electroglottography; Other: Air flow measurement + acoustic signal recording

Experimented beatboxer singer

OTHER

10 experimented beatboxer singer will be asked to reproduced the sounds record by the first subject (professional singer) while undergoing the different procedures.

Other: Nasofibroscopy; Other: Electroglottography; Other: Air flow measurement + acoustic signal recording; Other: Questionnaire

Interventions

Nasofibroscopy OTHER

Laryngeal exploration performed using a flexible fibrescope while singing.

Experimented beatboxer singer; Professional beatboxer singer

Electroglottography OTHER

Electrography of glottal movement using the EG2-PCX2 system (Glottal enterprises) while singing.
