Phonetics is a branch of linguistics that studies the physical aspects of speech sounds. It is concerned with the production, transmission, and reception of speech. Phonetics can be divided into three main areas: articulatory phonetics, acoustic phonetics, and auditory phonetics.

Articulatory phonetics focuses on how speech sounds are produced by the vocal organs. This includes the study of the lungs, larynx, vocal cords, tongue, lips, and teeth, and how they work together to create different sounds.

Acoustic phonetics deals with the physical properties of speech sounds as they travel through the air. This involves analyzing sound waves, their frequencies, amplitudes, and durations, often using tools like spectrograms.

Auditory phonetics investigates how speech sounds are perceived by the listener. This area examines the ear and the brain's interpretation of sound waves, including how we distinguish between different sounds and understand spoken language.

The International Phonetic Alphabet (IPA) is a standardized system developed to represent all the speech sounds used in human languages. Each symbol in the IPA corresponds to a unique sound, allowing for precise and consistent transcription of pronunciation, regardless of the language or dialect. Phonetics plays a crucial role in fields such as speech therapy, language teaching, lexicography, and the study of language acquisition.
