Phonetics and Phonology

Phonetics is a field of linguistics that deals with linguistic sounds. The term is also used for sign languages; there she deals with the gestural and visual components of signs.

Phonetics studies the physical production, transmission and perception of linguistic sounds. Phonology, on the other hand, is about the function of sounds within a language. The phoneme plays an important role here. Phonemes are units of perception that differ in meaning and represent the building blocks of the (spoken or signed) words of a language.

transcription

Phonetic transcription is a method of reproducing the sounds occurring in human languages ​​regardless of their spelling. The best known system is the International Phonetic Alphabet (IPA), which is predominantly based on the Latin alphabet and can transcribe properties of languages ​​such as consonants, vowels and suprasegmental properties. It was developed by the International Phonetic Association as a standardized representation of the sounds of human languages. The IPA is used by lexicographers, foreign language teachers and learners, linguists, speech pathologists, singers, actors, planned language creators, and translators.

Relationship between Phones and Phonemes

The phon is the fundamental unit of sound in human language; the phoneme is the basic unit of sound in individual languages. A phoneme is an abstract unit of a certain language and comprises a number of different phones. This is reflected in different levels of transcription. The purpose of phonetic transcription (usually in square brackets) is to transcribe sounds (phone) in such a way that the exact articulation is reproduced, while phonemic transcription (usually between slashes) transcribes words according to the classification of the sounds in a particular language . The separation between phonemic and phonetic transcription is not always clear: the narrow phonetic transcription captures more sound variations, while the broad phonetic transcription only reproduces the most conspicuous properties and merges into the phonemic transcription.
