I am not a native speaker of English language. Therefore, I have strong mother tongue influence on my English accent. Also, when I speak in English, I face difficulty in pronouncing certain words. Will this forum help me? Will the knowledge of phonology and phonics help me?
You can ask questions about pronunciation in this forum, which will help you with your accent.
‘Phonology’ a big academic word that spans nearly everything to do with pronunciation. I suggest you pick a specific area and concentrate on that for a while, e.g. English word stress, English rhythm or how to articulate sounds.
Lastly, I will say that you have set an unhelpful goal regarding your accent. While we can aim for perfection, it can never be achieved. I think a much better goal is to aim for a clear, understandable accent. Lots of lessons about English pronunciation and learning mindset are available on my website:
