(linguistics) The feature of a language of only allowing voiceless consonants before a pausa.

Final-obstruent devoicing or terminal devoicing is a systematic phonological process occurring in languages such as Catalan, German, Dutch, Quebec French, Breton, Russian, Polish, Lithuanian, Turkish, and Wolof.

In phonology, voicing (or sonorization) is a sound change where a voiceless consonant becomes voiced due to the influence of its phonological environment; shift in the opposite direction is referred to as devoicing or surdization.
