what are the differences between phonetics and phonology?​

Answer :

Phonetics studies the physical aspects of speech sounds by humans. Phonology is the study of patterns of sounds and how variation in speech sounds differ.
Phonetics deals with the production of speech sounds by humans, often without prior knowledge of the language being spoken. Phonology is about patterns of sounds, especially different patterns of sounds in different languages, or within each language, different patterns of sounds in different positions in words etc.
