Experimental-Phonetic Analysis of the Phonetic Structure of Word in the English language

,


Introduction
It is important to use experimental-phonetic method for the investigation in the modern linguistics. The work of the researcher in the experiment does not end only with the selection of appropriate research methods, the identification of important components and the correct execution of the experiment. The main problem facing the researcher is to provide a linguistic analysis of the results of the experiment in accordance with the theoretical propositions (Veysally, 2005).
It is possible to receive information about the speech sounds in modern instruments. However, it is impossible to say anything about the linguistic essence of this issue. The fact that the oscillograms and spectrograms are of high quality is not a problem, it is the researcher's ability to "expand" them (Veysally, 2005).
The experiment also sets certain requirements for the researchers. The experiment requires the researcher to have theoretical knowledge of the investigated problem. Prof. Scherba noted that the language material and language facts obtained from the experiment were based on his linguistic ideas (Scherba, 1979). According to Veysally, the phonetic study of any material can be qualitative only if it is based on experiment rather than observation (Veysally, 2005).
About oscillographic analysis, Veysally writes: "The main difficulty in working on oscillograms is related to the correct division of segments and determination of their boundaries" (Veysally, 2005).
Our aim is relying on these principles, the principle of importance of the experimental study, to carry out experimental analysis of the word in the English language.

Scope of the Study
Experimental-phonetic method plays a very important role in the investigation of modern linguistic problems. In order to perform the experiment accurately, some conditions must be met. One of them is the selection of announcers to record the experimental material on tape and informants who will listen to the recorded language material. "PRAAT" computer program was used in the phonetic study of the material. The indicators about the acoustic parameters were obtained by means of a computer program. The experimental-phonetic method allows us to have an objective opinion about the phonetic features of stress. Therefore, the application of the instrumental research method is of great importance in the study of languages and their repetition. Among the acoustic parameters, melody plays the leading part. Veysally notes that the rise and fall of the voice tone in the act of conversation is its melody, and the results obtained at the end of the research depend on it, so it is important to pay special attention to it (Veysally, 2003). ijel.ccsenet.
The maximum intensity of the vowel / ı / in the English word "аrchbishоpric" /ˌа:ʧ 'bıʃəprıк/ was recorded -89 db. The analysis shows that the maximum intensity was recorded in the / ı / vowel in the word "discоntinuе" /ˌdıskən'tınju:/ -82 db. In the words "misdoing" /mıs'du:ıŋ / and "misconceive" /mıskən'si:v/, the maximum intensity is recorded in the vowels /u / and /ı /. In the first word, the intensity is 84 db, and in the second word, the intensity is 81 db.
In the analyzed words "revisit" /rı'vızıt/ and "polyphonic" /ˌpɒlı'foʊnık /, the maximum intensity was recorded in the amount of 81 db in the vowel /ı / of the first word, and 86 db in the diphthong / oυ / of the second word. In the word "polyphonic" /ˌpɒlı'foʊnık/ the intensity of the syllable carrying the secondary stress is 82 db in the vowel /ɒ /. The word "poly semantic" /ˌpɒlısı'maentık/ in the English language, the intensity is distributed between syllables carrying the secondary and primary stress-in the following ratio: 85-90 db. In the words "semi-automatic" /ˌsеmı ɔ:t ə'm ae tık/ and "anti-body" /'aentı ˌbɒdı/, the intensity is 88-85 db in the stressed syllables, respectively. In these words, the intensity is very low in the syllables carrying the secondary stress: 79 db -76 db.
In the words "individuality" /ˌindıˌvıdu'aelətı/ and "individualistic" /ˌindıˌvıduə'lıstıк /in the English language, the intensity in the stressed syllables is noted in the following indicators: 89-90 db. On the other hand, the intensity is relatively low in the syllables carrying the secondary stress -81-82 db.
We would like to point out that in the course of speech, speech sounds have different lengths depending on the time. Prof. Sherba considered the length (time) to be the main component in the sentence (Scherba, 1979). For this reason, the length parameter is more important than the intensity and frequency of the main tone in the phonetic characteristics of speech sounds.
Zinder notes: "The length of the syllable is usually directly dependent on phonetic conditions, more precisely, on phonetic positions. The length of the phonemes is often different in the open and closed syllables. It depends on the acoustic quality of the preceding and following consonants (plosive or constrictive, voiceless or voiced), the number of consonants that come after the vowel, the place of stress (stressed syllable, preceding stress, following time spent on their pronunciation also decreases. In other words, the maximum time is inversely proportional to the number of the syllables. Among the factors affecting the length of speech sounds, Zinder also noted the influence of the number of syllables: "… the time length depends on the phonetic conditions, more precisely, on the phonetic position and also on the number of syllables in the speech (Zinder, 1979).

Conclusion
Experimental-acoustc analysis of the materials of the English language helps us to come to the following conclusions: In the English language, the maximum tone frequency is proportional to the primary stressed syllables: in the English word "impossibility" /ımˌpɒsəʹbıləti/, the main tone frequency is 236 hs for the vowel /ı/ in the primary stressed syllable, and 219 hs for the secondary stressed syllable. In the words "onomatopoeia" /ˌɒnəʊˌmaetəʹpi:ə/, "palatalization" /ˌpaelətəlаıʹzeıʃn/ and "industrialization" /ınˌdʌstrɪəlаɪʹzeɪʃn/, the tone frequency in the main stressed syllables is expressed by the following parameters: 230-210 hs, 240-213 hs, 227-204 hs, 216-199 hs.
In the English language, the maximum tone frequency is recorded in the second syllable in complex abbreviated words. Maximum tone frequency is observed in the stressed syllables.
In the English language, the highest tone frequency was noted in the syllables with the maximum tone frequency.
Maximum intensity parameters such as main tone frequency and length parameters are characteristic of stressed syllables. For example, in the words "Infinitive" / ɪ n'f ɪ n ə t ɪ v / (1) 73: 79 db. and "abstract" /'aeb s t r ae k t/ is 79:84 db (see: gr. 3.3).
One of the factors that influences on the length of syllables is the number of the syllables in the word. The results of the experiment show that whenever the number of syllables in a word increases, the time length spent on them decreases. The maximum time spent is on the stressed syllable.
The average time spent on the pronunciation of primary stressed syllables in English compared is much more than the average time spent on the syllable carrying the secondary stress.
Maximum intensity indexes as well as the maximum tone frequency and length parameters are typical for the stressed syllables.
