Language and Music, Speech and the Human Beatbox: Theoretical Issues for Research in General and Applied Linguistics (HBB)

February 27, 2023 updated by: Hopital Foch

Language and Music, Speech and the Human Beatbox: Theoretical Issues for Research in General and Applied Linguistics; Monocentric Exploratory Study

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 Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

HBB is characterized by two very interesting aspects (1) the complexity of the oro-pharyngo-laryngeal joints and the articulatory precision of the beatboxers and (2) the respiratory management which allows the artists to beatbox continuously without interrupting their performance. These two points, very characteristic of this technique, allow them to best imitate diverse and varied musical tones.

The Human Beatbox is still little studied and the literature on this subject is quite limited. Percussive sounds (for example imitations of bass drums, hi-hat or snare) seem to be characterized by articulatory strategies, melodic sounds (for example wind instruments, strings) seem to be based on both articulatory and phonatory strategies, and finally, electronic sounds seem to mainly use complex phonatory strategies.

Our objectives are to better understand the articulatory capacities and limits of the vocal tract at different levels (articulation capacities, sound production mechanisms, muscular and acoustic temporal relationships, strategies of efficiency...).

It is possible to find clinical applications of the Human Beatbox in the context of congenital speech disorders (for example dyspraxia) or acquired (for example oro-pharyngo-laryngeal surgery of the partial glossectomy type).

Interventional

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
