vocal linguistic concretization utilization process A linguistic concretization utilization process where the GDC includes words or expressions of a language and is concretized as sound waves in the air which are generated by the participant. It must include words or expressions specific to a particular language. This avoids clapping or other non-voice sounds falling under the definition. Matthew Diller Speaking and singing are both encompassed and should be subclasses if & when needed. The sound wave is a quality of the air, a pattern of rarefactions and compressions, sequentially over time. We don’t say ‘vocal cords’ because we want to include computer-generated voice via speakers, ear buds, headphones, etc, etc. We could have a child class specific to use of organisms' vocal cords eventually if & when needed.
