Evolutionary Phonology. Evolutionary Phonology seeks to derive typological generalizations from recurrent patterns of language change, themselves assumed to be rooted in perception, production, and acquisition. The goal is to eliminate UG by providing diachronic explanations for the cross-linguistic evidence that has been used to motivate it. (2) shows a schema of this program, where the arrows can be read as “explains” and/or “constrains”.

Phonemes are minimal segments within the spoken message whose presence is relevant for distinguishing one message from a different one with another meaning. Each phoneme underlies different phonetic realizations. What sets a phoneme from another is fuzzy cluster of the fuzzy features. Thus the study of phonemic structures is likely to have much to gain from a gradualistic approach. Through a gradualistic treatment synchronic phonology could tally with the diachronic study in a simpler way than is customary. In this connection, (...) an obstacle to be overcome is a widespread adherence to classical logic. (shrink)

In the 1920s and 1930s, some of the most talented linguists of the Soviet Union, among whom one can highlight N.F. Jakovlev and E.D. Polivanov, were involved in the process of “language building”. Their role in the success of this process is examined from the point of view of the phonological theory that they developed for creating scripts for the numerous peoples of the Soviet Union, Turkic and Caucasian above all. Jakovlev’s phonology, that Polivanov termed “social phonology”, was very different (...) from the one that N. Trubetskoj proposed some 10 years later. We will try to explain their ambitious script projects, which remain difficult to understand from the point of view of the modern phonology. (shrink)
