Allofonet

Allofonet is a theoretical unit in phonology designed to represent the set of realizations of a single phoneme across languages or dialects as a single underlying object. The term combines allophone and phoneme to indicate that surface variants, conditioned by context, are treated as manifestations of one underlying allofonet. The concept aims to facilitate cross-language comparison of phoneme realization by focusing on common perceptual and articulatory properties shared by its variants.

Representation and rules: An allofonet is described by a feature bundle that captures salient cues such as place and manner of articulation, voicing, and timing. Language-specific phonetic outputs are derived by mapping rules that select a given variant from the allofonet's set according to phonotactic context, phonological processes, and dialectal rules. In this view, differences among languages are attributed to surface-realization rules rather than to separate underlying phonological units.

Example and potential applications: For instance, a phoneme with aspirated, unaspirated, and alveolar flap realizations across different languages could be modeled as one allofonet with language- and context-dependent variants. Potential applications include typological research, and multilingual speech recognition and synthesis, where a compact representation of cross-language variation can be advantageous.

Status and critique: Allofonet remains a niche, theoretical proposal not widely adopted in mainstream phonology. Critics caution that collapsing variants may obscure legitimate phonological distinctions, while proponents argue that it offers a valuable framework for cross-language comparison and computational modeling.
