TAILIEUCHUNG - Báo cáo khoa học: "Analysis and Synthesis of the Distribution of Consonants over Languages: A Complex Network Approach"

Cross-linguistic similarities are reflected by the speech sound systems of languages all over the world. In this work we try to model such similarities observed in the consonant inventories, through a complex bipartite network. We present a systematic study of some of the appealing features of these inventories with the help of the bipartite network. An important observation is that the occurrence of consonants follows a two regime power law distribution. We find that the consonant inventory size distribution together with the principle of preferential attachment are the main reasons behind the emergence of such a two regime behavior | Analysis and Synthesis of the Distribution of Consonants over Languages A Complex Network Approach Monojit Choudhury and Animesh Mukherjee and Anupam Basu and Niloy Ganguly Department of Computer Science and Engineering Indian Institute of Technology Kharagpur monojit animeshm anupam niloy @ Abstract Cross-linguistic similarities are reflected by the speech sound systems of languages all over the world. In this work we try to model such similarities observed in the consonant inventories through a complex bipartite network. We present a systematic study of some of the appealing features of these inventories with the help of the bipartite network. An important observation is that the occurrence of consonants follows a two regime power law distribution. We find that the consonant inventory size distribution together with the principle of preferential attachment are the main reasons behind the emergence of such a two regime behavior. In order to further support our explanation we present a synthesis model for this network based on the general theory of preferential attachment. 1 Introduction Sound systems of the world s languages show remarkable regularities. Any arbitrary set of consonants and vowels does not make up the sound system of a particular language. Several lines of research suggest that cross-linguistic similarities get reflected in the consonant and vowel inventories of the languages all over the world Greenberg 1966 Pinker 1994 Ladefoged and Maddieson 1996 . Previously it has been argued that these similarities are the results of certain general principles like maximal perceptual contrast Lindblom and Maddieson 1988 feature economy Martinet 1968 Boersma 1998 Clements 2004 and robustness Jakobson and Halle 1956 Chomsky and Halle 1968 . Maximal perceptual contrast between the phonemes of a language is desirable for proper perception in a noisy environment. In fact the organization of the vowel inventories across languages has been .
