If there is one thing I would change, it would be the alphabet we use. 1 letter for every sound. “A” has so many versions, e.g.
Only problem is we would probably end up with 75 letters.
Only problem is we would probably end up with 75 letters.
The number would depend on how many different variations we chose to represent.
Another potential problem is dialectal: even within the same country, different dialects and accents use different pronunciations. Which pronunciations do we follow in devising a "phonetic" alphabet? I imagine a range of solutions, each of which sacrifices something.
Even so, I probably would prefer an English alphabet that at least better represented different vowels.
