Phonetics is primarily concerned with the study of the sounds of human speech. This field examines how sounds are produced, transmitted, and perceived, allowing linguists to analyze the physical characteristics of speech sounds, known as phonemes. By understanding phonetics, language researchers can delve into how different sounds distinguish meaning in various languages.

The focus on the physical properties of sound, such as articulation (how sounds are made), acoustics (how sounds travel), and auditory perception (how sounds are heard), aligns perfectly with the study outlined in the correct choice. This foundational knowledge is crucial for various language-related fields, including linguistics, language teaching, and speech therapy.

In contrast, the other options cover different aspects of language studies, such as syntax (rules of sentence structure), visual communication, and language acquisition, none of which directly relate to the study of speech sounds as phonetics does. Understanding these distinctions helps clarify the specific role phonetics plays within the broader context of linguistic studies.
