Methods of phonetic analysis

The phoneme theory and its main trends

The founder of the Phoneme Theory was the Russian scientist Boudoin-de-Courtenay who was the head of the Kazan Linguistic School. He defined the phoneme as a physical image of a sound. He also regarded phonemes as fictitious units and considered them to be only perceptions. This approach is called mentalistic/ physical.

Ferdinand de Saussure viewed phonemes as the sum of acoustic impressions and articulatory movements. He also viewed phonemes as disembodied units of the language formed by the differences separating the acoustic image of one sound from the rest of the units. Language in his opinion contains nothing but differences. This approach is called abstractional/ abstract.

Trubetskoy (the head of the Prague Linguistic School) defined the phoneme as a unity of phonologically relevant features. Relevant feature is the feature without which we can’t distinguish one phoneme from another. This approach is called functional.

Phonemes can be neutralized. In this case we receive an archi-phoneme. That is a unity of relevant features common to both phonemes (e.g. wetting – wedding in AmE). In case of archiphoneme we cannot distinguish one phoneme from another. Thus the distinctive function of the phoneme is lost.]

Another kind of approach to the nature of the phoneme was expressed by a British scholar, the head of the London School of Phonology, Daniel Jones. He defined the phoneme as a family of sounds.

The American Linguistic School (Blumfield, Sapir, etc) defined the phoneme as a minimum unit of distinctive sound features and as abstractional unit.

The materialistic approach was expressed by Leo Tsherba. Academician Tsherba defined the phoneme as a real independent distinctive unit which manifests itself in the form of its allophones. This approach comprises the abstract, the functional.

We distinguish between subjective, introspective methods of phonetic investigation and objective methods.

The oldest, simplest and most readily available method is the method of direct observation. This method consists in observing the movements and positions of one's own or other people's organs of speech in pronouncing various speech sounds, as well as in analyzing one's own kinaesthetic sensations during the articulation of speech sound in comparing them with auditory impressions.

Objective methods involve the use of various instrumental techniques (palatography, laryngoscopy, photography, cinematography, X-ray photography and cinematography and electromyography). This type of investigation together with direct observation is widely used in experimental phonetics. The objective methods and the subjective ones are complementary and not opposite to one another. Nowadays we may use the up-to-date complex set to fix the articulatory parameters of speech - so called articulograph.

Acoustic phonetics comes close to studying physics and the tools used in this field enable the investigator to measure and analyze the movement of the air in the terms of acoustics. This generally means introducing a microphone into the speech chain, converting the air movement into corresponding electrical activity and analyzing (Ксень, это слово у Красы через «s», но, по-моему, тут «z») the result in terms of frequency of vibration and the amplitude of vibration in relation to time. The spectra of speech sounds are investigated by means of the apparatus called the sound spectrograph. Pitch as a component of intonation can be investigated by intonograph.

The acoustic aspect of speech sounds is investigated not only with the help of sound-analyzing techniques, but also by means of speech-synthesizing devices.

7. There are different types of oppositions:

1) single

the opposed sounds differ in one articulating feature only: [ p en] – [ b en]

voiceless voiced

2) double

the opposed sounds differ in 2 distinctive features: [ p en] - [ d en]

bilabial forelingual

voiceless voiced

3) triple (multiple)

the opposed sounds differ in 3 distinctive features: [pen] - [then]

voiceless voiced

bilabial interdental

occlusive stop constrictive fricative

There are some problems - sometimes sounds cannot be opposed:

Ex: [h] is never used in final position;

[n-носовое] is never in the initial position.

In such cases we rely on the knowledge of the native speaker and phonetic similarities or dissimilarities.
