Pronunciation in any language is the result of the work of the auditory-speech system, part of which is the actual speech apparatus and french to english. By itself, it is a combination of organs of the oral cavity and larynx involved in the generation of sound. These are, first of all, the vocal cords, tongue, lips, hard and soft palate and teeth. They form the structure of certain muscles, ligaments and cartilage, which are trained from early childhood to pronounce phonemes (sounds) of their native speech, therefore, in order for an adult to speak a foreign language well, this physical structure should be specially trained. Fortunately, like all other muscles, the speech apparatus lends itself to gymnastics and control by consciousness at any age in accordance with the well-known rule: the more we trained in youth, the more plastic and supple our body is in maturity. This is also why the study of the second, third and so on of a foreign language is easier than the first.
The generation of any sounds by the vocal apparatus is provided by the air flow, since normally we speak on the exhale. Speech is directly related to all respiratory organs, and special attention should be paid to the diaphragm: when we worry too much, we experience stress, the diaphragm is most often “clamped”. Therefore, if we already have problems with pronunciation, then the inability to breathe and control our diaphragm exacerbates them.
From the neuropsychological side, the central or managerial part of the auditory-speech system is a set of certain brain structures responsible for the perception, recognition and generation of speech. Please note that the name “auditory” is not accidental: hearing and speech are connected into a single system, they are born together, live and die together. A vivid proof of this is the problem of the existence of deaf and dumb people, while deafness and dumbness, taken separately, most often result from injuries or infections.
The quality of our speech and pronunciation, among other things, are ensured by the coordinated work of all components and levels of the auditory-speech system. It will not be possible to come to a good pronunciation in a foreign language if the phonemic (speech) hearing in relation to the required language is not sufficiently pumped, or if you breathe incorrectly when you speak, or if the muscles directly involved in articulation are not trained to pronounce sounds foreign language. Also, all attempts at good pronunciation will shamelessly spoil the intonation, tempo and rhythm of speech in the event that they do not correspond to the language you speak. It also matters how much you generally pay attention to your diction. It is unlikely that someone will be able to speak a foreign language better than their own, so the habit of mumbling, chattering or mumbling under your breath will also not serve you well in developing a foreign pronunciation.
