One of the main features of experimental research is conducting experiments on speech 
perception, i.e. perceptual (from Lat. perception "perception") experiments. “Speech 
perception” thus refers to the set of operations that transform an auditory signal into 
representations of a form that makes contact with internally stored information – that is, the 
stored words in a listener’s mental lexicon. 
Speech perception is considered in psychology and physiology of speech, in psycholinguistics 
and psychology of speech, it is also an integral part of experimental phonetics. This is stated in 
the linguistic encyclopedic dictionary as follows: "Speech perception is in experimental and 
general phonetics a set of mechanisms that ensure the transition from the primary phonetic 
description of a sound or a sound sequence to its interpretation as a certain unit of the language 
system. In this regard, the perceptual correlates of supra-segmental units (stress, intonation), 
which are used in the perception of sound units of different levels, are investigated". The 
modern stage of the development of linguistics is characterized by an increased interest in the 
problem of studying various aspects of sounding speech. One of the promising areas that have 
recently attracted linguists, is perceptual phonetics, which studies the peculiarities of 
perception of foreign language speech. Human perception is a complex process of receiving 
and processing information. Scientists note a number of differences that exist between the 
perception of written and spoken speech. In the process of reading, it is possible to control the 
rate of information receipt and segment the incoming signal, which seems impossible when 
perceiving the message by ear. 
Difficulties of perception can arise not only because of the nature of a different sound of 
segmental speech (sound - syllable - word), but also at a super-segmental level (division into 
syntagmatic, logical stress and verbal stress). While the situation or context often helps native 
speakers in perceiving a particular language reality, listeners for whom the sounding speech is 
not native rely mainly on the phonetic component. Thus, any deviations from the 
pronunciation norm will interfere with the perception of information by those for whom 
English is not their native language. 
It is known that in English words can vary in sound depending on whether they are 
pronounced in the flow of speech or isolated. Interconnected sound combinations are 
pronounced in the speech stream- the articulation of any sound is influenced by the articulation 
of neighboring sounds, i.e. it is subject to co-articulation. There are no pauses in coherent 
speech that correspond to the intervals of written speech. As a rule, pauses in speech are used 
not between two words following each other, but between groups of words that can be 

---

considered one phonetic segment. Such a combination of sounds, pronounced by native 
speakers, is deciphered through the situation and with the help of standard phrases. 
It should be noted that when conducting a perceptual-auditory experiment, sounds, isolated 
words, words in the speech stream, etc. can act as the studied material. It depends on the 
purpose and purpose of the study. But in general, if we talk about the technique of preparing 
and conducting a perceptual audit experiment, all the above requirements should be observed. 
Sum up, the features of the perception of speech sounds by the human hearing organ is 
examined by auditory phonetics, in particular by perceptual-auditory experiment. It is designed 
to answer the questions about what sound properties are essential for human perception of 
speech (for example, for recognizing a given phoneme), taking into account the changing 
acoustic and articulatory characteristics of speech signals, that is, what are the perceptual 
correlates of relevant (essential) features of phonemes and prosodies. There is a consideration 
that people in the process of perceiving sounding speech extract information not only from the 
acoustic properties of the utterance but also from the linguistic context and communication 
situation, predicting the general meaning of the perceived message.
