What is phonology?

Phonology is the study of the patterns of sounds in a language and across languages. Put more formally, phonology is the study of the categorical organisation of speech sounds in languages; how speech sounds are organised in the mind and used to convey meaning. In this section of the website, we will describe the most common phonological processes and introduce the concepts of underlying representations for sounds versus what is actually produced, the surface form.

Phonology can be related to many linguistic disciplines, including psycholinguistics, cognitive science, sociolinguistics and language acquisition. Principles of phonology can also be applied to treatments of speech pathologies and innovations in technology. In terms of speech recognition, systems can be designed to translate spoken data into text. In this way, computers process the language like our brains do. The same processes that occur in the mind of a human when producing and receiving language occur in machines. One example of machines decoding language is the popular intelligence system, Siri.

Phonology vs. Phonetics – the key differences

Phonology is concerned with the abstract, whereas phonetics is concerned with the physical properties of sounds. In phonetics we can see infinite realisations, for example every time you say a ‘p’ it will slightly different than the other times you’ve said it. However, in phonology all productions are the same sound within the language’s phoneme inventory, therefore even though every ‘p’ is produced slightly different every time, the actual sound is the same. This highlights a key difference between phonetic and phonology as even though no two ‘p’s are the same, they represent the same sound in the language.
