I have to perform a context switch between “v” and “w” sounds, so words and phrases that contain both (e.g: “very well”) sometimes end up with only “w” sounds. (My native language does not have a regular “W” sound) But even after 20 years speaking it, English pronunciation is complete nonsense. Most of the time, you just need to memorize the words. Because trying to figure out how to say something, you also need to know if the word is borrowed from any other languages that use Latin alphabet, and then pronouce it pretending to speak that language. Simplest example: Mocha (moh-ka) and matcha (maht-cha). But there are countless borrowed words that don’t change spelling in English.
