fonetinenphoneminen

Fonetinen phoneminen, or the phonetic-phonemic distinction, is a foundational concept in linguistics describing two levels at which speech sounds can be analyzed. Phonetics studies the physical properties of sounds as they are produced, transmitted, and perceived—phones—covering articulatory gestures, acoustic signals, and perceptual cues. Phonemics studies the sound system of a language as a set of contrastive units called phonemes, which serve to distinguish meaning.

The key difference is that phones are concrete realizations of sounds, while phonemes are abstract, functional units in a language’s mental representation. Allophones of the same phoneme occur in complementary distribution or free variation, and do not by themselves change meaning. For example, in English the phoneme /p/ has different allophones: aspirated [pʰ] as in pat, and unaspirated [p] as in spin. In contrast, the phonemes /p/ and /b/ distinguish words such as pat and bat.

In practice, phonetic data describe how sounds are actually produced and heard, whereas phonemic analysis explains how sounds function to differentiate words within a language. Broad transcription (phonemic) uses slashes / /, while narrow transcription (phonetic) uses brackets [ ] with diacritics to capture fine-grained details.

This distinction underpins many areas of linguistics, including language description, teaching, and speech technology. It helps researchers and teachers decide what counts as a meaningful difference in a given language and how to represent it in analysis and transcription.
