Acoustic linguistics refers to the study of language sounds, specifically the physical properties of speech sounds and how they are produced, transmitted, and perceived. It involves the analysis of the acoustic signals that make up speech, including the study of pitch, frequency, amplitude, and duration of sound waves.

In the context of linguistics, acoustic analysis helps researchers understand the variations in speech sounds across different languages and dialects. It plays a crucial role in fields such as phonetics, speech recognition technology, and linguistics research, allowing experts to explore the nuances of human speech and improve our understanding of language patterns.
