In other words, phonetics and vocabulary play a pivotal role in speaking a language and in the crisp quality of your communication. Acing English requires apt use of phonetics and vocabulary with other factors. Good phonetics and vocabulary add to your speaking skills in the English language.
Phonetics is the basics of any language. It reflects the way sounds are produced by the speech organs like lips, tongue and lungs, and it relates to the sound of a word. The shape of lips, the swirl of the tongue and the modification of the airstream by the larynx plus the articulatory organs enable the production and articulation of speech sounds.
Phonetics is part/branch of linguistics and a significant part of the human's actual speech "sound part". The foundation of phonetics, correct pronunciation of words and the proper use of phonetics can drastically improve your English. You may sound like a Native-English speaker when you practice phonetics regularly. All the alphabets and words parts of speech must sound correctly or almost like a native speaker of the English language. There are branches of phonetics, such as articulatory, acoustic, instrumental, etc.
Vocabulary refers to all the words you know and are familiar with. It is a must to increase your vocabulary daily, especially if you wish to expedite this in a set time frame, for instance, before the IELTS, PTE or any other language proficiency test or entering the desired country like the US, the UK, Canada, Australia, and New Zealand. A rich vocabulary can make an exponential difference in your English speaking, writing, reading and listening/understanding skills.
Both Phonetics and vocabulary go hand in hand. If you have a good hold on vocab but can not pronounce the words correctly, it might not serve good.
There are many ways to improve your pronunciation as per the words' phonetics and increase your vocabulary, such as joining English coaching classes, watching specific TV programs, English movies, news, practising speaking with peers, copying the words' speech of a native-language speaker. Having A mentor would also guide you through these aspects and steps to have the correct phonetics.
