A phoneme is the smallest abstract unit of sound in a given language such that substituting one phoneme for another in a word changes the word's meaning (minimal pair distinction). Parameters include: the language or dialect to which the phoneme system belongs, the inventory of phonemes (typically 20-100 sounds per language), the distinctive features that differentiate phonemes (voicing, place and manner of articulation for consonants; height, backness, roundedness for vowels), and the allophonic variants (context-dependent phonetic realizations of the same phoneme). The persistence mechanism is the phonological theory and classification system codified in descriptive grammars, the International Phonetic Alphabet (IPA) chart, language documentation projects, and phonetic transcription standards used in linguistics, computational language processing, and speech recognition systems.

Definition
Why it is in scope
The smallest unit of sound in a language that can distinguish meaning between words. Human-made as a theoretical construct in phonology, persisted through linguistic analysis, language teaching, speech technology, and the IPA (International Phonetic Association) classification system.

The concept of phoneme is built for the sake of language: phonemes are the abstract sound units that distinguish meaning within a language, and the concept exists to serve the analysis, description, and teaching of language. The arrow points servant→master: phoneme serves language. This is by design/academic practice, not incidental benefit.

Phonemes are the fundamental acoustic-linguistic units that speech recognition systems target for identification. The concept of phoneme serves the practice of speech recognition by providing its unit of classification.
