Abstract
We review and elaborate an account of consonantal strength that is founded on the model of speech as a modulated carrier signal. The stronger the consonant, the greater the modulation. Unlike approaches based on sonority or articulatory aperture, the account offers a uniform definition of the phonetic effect lenition has on consonants: All types of lenition (such as debuccalisation, spirantisation and vocalisation) reduce the extent to which a consonant modulates the carrier. To demonstrate the quantifiability of this account, we present an analysis of Ibibio, in which we investigate the effects of lenition on the amplitude, periodicity and temporal properties of consonants. We propose a method for integrating these different acoustic dimensions within an overall measure of modulation size. Not only does the modulated-carrier account cover all the classically recognised lenition types, but it also encompasses loss of plosive release in final stops – which, although not traditionally classed as lenition, is clearly related to processes that are.
期刊介绍：
Phonology, published three times a year, is the only journal devoted exclusively to the discipline, and provides a unique forum for the productive interchange of ideas among phonologists and those working in related disciplines. Preference is given to papers which make a substantial theoretical contribution, irrespective of the particular theoretical framework employed, but the submission of papers presenting new empirical data of general theoretical interest is also encouraged. The journal carries research articles, as well as book reviews and shorter pieces on topics of current controversy within phonology.
