Phonetics is the study of speech sounds, including their production, transmission, and perception.

Phonemes are units of sound that distinguish one word from another in a language. They are not speech sounds themselves, but rather abstract representations of sounds.

The place of articulation is the point in the vocal tract where the airstream is obstructed or modified to produce a speech sound.

Nasal is a place of articulation, not a manner of articulation. The manner of articulation refers to the way in which the airstream is obstructed or modified to produce a speech sound.

Voicing is the vibration of the vocal cords during speech. It is a feature that distinguishes voiced sounds from voiceless sounds.

Aspiration is a feature of voiceless stops, not voiced stops.

Assimilation is the process of changing a speech sound into another sound due to the influence of a neighboring sound.

Distant assimilation is not a type of assimilation. Progressive assimilation is the process of a speech sound changing to become more like a following sound, while regressive assimilation is the process of a speech sound changing to become more like a preceding sound.

Auditory phonetics is the study of the perception of speech sounds.

Discourse analysis is a method of studying language use in context, not a method of auditory phonetics.

Articulatory phonetics is the study of the production of speech sounds.

Laryngoscopy is a method of examining the larynx, not a method of articulatory phonetics.

Phonology is the study of the relationship between speech sounds and meaning.

Psycholinguistics is a branch of psychology, not a branch of phonology.

A phoneme is the smallest unit of sound that can distinguish one word from another in a language.
