REALISATION OF VOICED-UNVOICED OF OBSTRUENT CONSONANTS BEFORE INTERCONSONANTAL SONORANTS AND [V]

The article deals with the assimilation of obstruent consonants in initial position in consonantal combinations “obstruent + sonorant or [v] + obstruent”. The aim of the study was to reveal the “transparency” of sonorants and [v] in such groups, i.e. the possibility of distant assimilative influence of the last obstruent on the first one. It is proved that in the sound combinations “obstruent + sonorant or [v] + obstruent” the interconsonant sonorants do not prevent the regressive assimilative interaction of two obstruent consonants, i.e. the sonorants and [v] “pass through” the assimilation by voiced-unvoiced.The article presents the results of an experimental phonetic study of the realisation of obstruent consonants in the specified position within and at the junctions of phonetic words in the modern Russian literary language. The data obtained in the course of the study confirm that in the combinations “unvoiced obstruent + sonorant or [v] + voiced obstruent” within one phonetic word ( от льдинок [а д-л’д ’и ́ нък] , от мгновения [а д-мг нав’éн’ьь]), the initial consonant is voiced under the influence of the voiced consonant, and, on the contrary, in combinations “voiced obstruent + sonorous + unvoiced obstruent” ( из Мценска [и с-мц éнскъ], из ртути [и с-рт ýт’ь]), the initial consonant is unvoiced. At the junction of phonetic words, there is a voicing of the final obstruent of the first word ( факультет МГИМО [фъкул’т’é д мг ’имó]).The article also analyses the articulatory, acoustic and functional specificity of [v], which combines the characteristic features of both obstruent and sonorous consonants. The functioning of soft [v’] in interconsonantal position in the above groups is not considered in the article, as it is not lexically represented.
