Phonetics is the study of the physical properties of speech sounds. It examines how the sounds are produced, transmitted, and perceived by the human ear. Phonetics deals with the articulatory, acoustic, and auditory aspects of speech sounds.
Articulatory phonetics looks at how sounds are produced by the articulators (the lips, tongue, and other parts of the mouth and throat), while acoustic phonetics focuses on the physical properties of sound waves. Auditory phonetics studies how speech sounds are perceived by the human ear and processed by the brain.
Phonology, on the other hand, is the study of the abstract sound system of a language. It examines how sounds are organized and used in language. Phonology deals with the underlying structures of speech sounds, including the phonemes, which are the smallest units of sound that can differentiate meaning in a language. Phonology also studies the rules and patterns of sound combinations in language, such as the rules of stress and intonation.

One way to illustrate the difference between phonetics and phonology is to consider the difference between a phone and a phoneme. A phone is a physical sound produced by the human vocal apparatus, while a phoneme is an abstract unit of sound that distinguishes one word from another in a language.
For example, the words "pin" and "bin" differ by only one sound, the initial consonant, which is either voiceless or voiced. In English, this distinction is represented by the phonemes /p/ and /b/. While the physical sounds of /p/ and /b/ are different, they are both phones. It is the abstract distinction between the phonemes /p/ and /b/ that is important for meaning in English.
Phonetics and phonology also have different goals and methods of analysis. Phonetics aims to describe and classify all possible speech sounds, including those found in non-human languages. Phonetics uses instruments such as spectrograms and electroglottographs to analyze speech sounds and measure their physical properties.
Phonology, on the other hand, aims to uncover the underlying patterns and rules that govern the sound system of a language. Phonology uses tools such as phonological rules and morphophonemic analysis to describe the structure and organization of speech sounds in a language.
In conclusion, phonetics and phonology are two related but distinct areas of linguistics that deal with the sounds of human language. While phonetics focuses on the physical properties of speech sounds, such as how they are produced, transmitted, and perceived, phonology studies the abstract sound system of a language, including the phonemes and the rules and patterns of sound combinations. By studying both phonetics and phonology, linguists can gain a deeper understanding of the sounds of language and how they are used to convey meaning.
