12. Methods of phonological analysis

The aim of phonological analysis is to establish distinctive difference between sounds, create the inventory of the phonemes and describe the phonemic system of a language. In other words, the aim of phonological analysis is the identification of the phonemes and their classification.

Each language has its own system of phonemes. Each member of the system is determined by all the other members and does not exist without them. The linguistic value of articulatory and acoustic qualities of sounds is not identical in different languages. In one language community two physically different units are identified as "the same" sound, because they have

similar functions in the language system. In another language community they may be classified as different because they perrorm a distinctive function. English speakers are not aware of the difference (of some similar phonemes) because it is of no importance in the communication process.

So the aim of the phonological analysis is, firstly, to determine which differences of sounds are phonemic and which are non-phonemic and, secondly, to find the inventory of the phonemes of a language.

There are two main approaches to phonological analysis. Formally distributional approach1 (распределительный подход) practised by American structuralists is focused on the position of the sound in the word, or its distribution. Semantic method2 attaches special importance to meaning. It is widely used in this country.

  1. Distributional method of phonological analysis.

The formally distributional method consists in grouping all the sounds pronounced by native speakers into phonemes according to the two laws of phonemic and allophonic distribution. The laws were discovered long ago and are as follows:

1. Allophones of different phonemes occur in the same phonetic context.

2. Allophones of the same phoneme never occur in the same phonetic context.

Two conclusions follow:

I. If more or less different sounds occur in the same phonetic context they should be allophones of different phonemes. In this case their distribution is contrastive. (контрастная дистрибуция)

2. If more or less similar sounds occur in different positions and never occur in the same phonetic context they are allophones of one and the same phoneme. In this case their distribution is complementary. (дополнительная дистрибуция)

  1. There is another method of phonological analysis widely used in Russian linguistics. It is called the semantically distributional method or semantic method. It is applied for phonological analysis of both unknown languages and languages already described. It is widely used in this country.

Semantic method attaches special importance to meaning. The analysis is performed through the system of phonological oppositions. It is based on the following fundamental phonological rule: phonemes can distinguish the meaning (words and morphemes) when opposed to one another in the same phonetic context ( day – they, sheep – ship). So to establish the phonemic status of a sound it is necessary to oppose one sound to some other sound in the same phonetic context. This procedure is called commutation test.

To conduct this test we must find the so-called minimal pairs. A minimal pair is a pair of words which differ in one sound only. So we replace one sound by another sound and try to find out if the opposed sounds belong to the same or different phonemes.

Now, the commutation test may have three possible results:

1. Pin – sin | the meaning is different so the opposed sounds belong to different phonemes.

2. P(h)in – pin | the meaning is the same so the opposed sounds belong to the same phoneme.

3. Pin – hin | we have a meaningless word, so we can’t make any conclusion about the phonemic status of the second sound, we can’t identify it.

It should be noted that there are different types of oppositions.

  1. If the members of the opposition differ in one articulatory feature the opposition is called single.

Pen – ben | [p] is fortis (voiceless), [b] is lenis (voiced).

  1. If there are two distinctive features, the opposition is double.

Pen – den | [p] is labial, fortis, [b] is forelingual, lenis.

  1. If three distinctive features are marked, the opposition is triple (multiple).

Pen –then | the differentiating features: occlusive – constrictive, labial – interdental, fortis – lenis.
