9. The Moscow school of linguistics and its contribution to the development of the phoneme theory.

The Moscow school of linguistics is presented by two basic approaches to the phoneme.

The first is morphological approach. It was headed by R.J. Avanessov, who developed Baudouin de Courtenay’s phoneme theory of the early period. He made a thorough analysis of this conception and introduced two notions:

1) phonemic variations;

2) phonemic variants.

Variations are the concrete representations of phonemes in “weak” positions, which are distinguished from phonemes, in “strong” positions (ex. vowels in stressed/unstressed positions).

Variants include all the alternation series that can be found within the same morpheme.

But such a complicated conception didn’t add precision to the morphological phoneme theory and on the contrary made it very obscure.

The second is cybernetic approach. Its originator is S.K. Showmyan, who has revised his views under the influence of L. Hjelmslev. According to Showman’s opinion, the phoneme can not be perceived by means of direct observation, as it is in the so called “Black Box”.

Showman has created a two-level theory of phonology and distinguished between two branches of phonology:

1) theoretical phonology;

2) general phonology.

Theoretical phonology is a new science which works out a conceptual apparatus for the study of the nature of phonological reality. General phonology studies the phonological systems of concrete languages.

So the cybernetic approach to the phoneme is rather abstract and obscure.

10. The Prague school of linguistics and its contribution to the development of the phoneme theory.

The Prague school of linguistics.nThe main points of Trubetzkoy’s theory are:

1) the separation of phonology from phonetics;

2) the theory of phonological oppositions;

3) the theory of the arch-phoneme.

Trubetskoy became acquainted with the phoneme theory through the works of Baudouin de Courtenay and Shcherba, while he was studying at the University of Moscow. But his views deviate greatly from those of Russian scholars. Trubetzkoy developed de Saussure’s principle of the separation of speech from language and proclaimed a new science – phonology as distinct from phonetics.

According to Trubetzkoy, phonetics is a biological science which investigates all physiological and physical features of speech sounds, that is to say, it should concern itself with the sounds of a language as they are pronounced and as they are heard, without paying any attention to their function in the language. Phonology is a linguistic science, which should concern itself with the distinctive features of speech sounds, that is to say, with those features which are connected with meaning and serve communicative purposes.

Trubetzkoy draws a strict borderline between a phonetician and a phonologist as well. A phonetician should study sounds without taking into consideration the meaning of what is said; a phonologist should take into account only those sound features which have a definite function in a language. But it is impossible to oppose phonetics and phonology as independent sciences, as phonology is a branch of phonetics.

Trubetzkoy gives the following definitions to the speech sound and the phoneme: The speech sound is a unity of both relevant and irrelevant features. The phoneme is a unity of phonologically relevant features of a sound. It can only perform its distinctive function if it is opposed to another phoneme in the same position. Such an opposition is called distinctive, or phonological. His theory of oppositions found its application in grammar where the majority of morphological categories can be presented as oppositions.

Trubetskoy’s theory of the arch-phoneme was based on Baudouin de Courtenay’s morphological phoneme theory, in particular the synchronical alternation of sounds in a morpheme. Trubetzkoy looked upon this phenomenon from the point of view of his opposition theory. Two phonemes can be neutralized because they have common qualities which do not occur in other phonemes. The phoneme in the position of neutralization is the arch-phoneme, which is defined as a unity of relevant features common to two phonemes. But arch-phoneme excludes the feature which distinguishes them. So arch-phoneme of [п - б] consists of the features: bilabial and plosive, but excludes voicing which separates them.
