I wouldn’t think anyone would try to memorize all of the sounds, both their orthography, audition and articulation without a desire to become a polyglot, linguist or both, and only after having learned a couple languages beforehand building a familiarity or a priming of oneself to better learn languages down the line.
Here is a link to the IPA chart on Wikipedia: https://upload.wikimedia.org/wikipedia/en/8/8f/IPA_chart_(C)2005.pdf
So to repeat my question, has anyone approached language learning in this way, learning the sounds relative to the languages that they are learning, one by one? Not from a letter system first but by sounds?
And has anyone tried then building from phonemes, to morphemes, from morphemes to words, and from words to syntax? Here I am asking if it may be better to learn in an planned fashion of building from the ground up.
Or like many, do you think it is better to start with the actual practice of listening, speaking, writing and reading as a whole, like in the immersion method? If so, do you find this other method or way an interesting one?
Do either think the two combined might offer greater benefit than either alone?
Thanks for reading. Thank you in advance for the responses.
