You're thinking of a world where people would still use a computer with a webcam pointed at their face while doing video calls. For me personally, I'm seeing a world where the headset is all that we need. So no, Persona is not a stopgap solution, it's an end in itself, and in its current state it's already pretty damn good.
Actually I'm thinking of a world where the masses accept an AR headset once it's as light as typical eye glasses. And before most people have these, the calls will be video. But I would be happy to be wrong!
Not if you account for variations of pronunciation in dialects. Not even the most phonetically accurate accent, the Hanoian Northern accent which I am a native speaker of, is perfect.
For example, you could hear Northern Vietnamese people say "dổ", "dá" instead of "rổ", "rá". Morning dew is pronounced "xương" but is written as "sương". These characters are pronounced with greater clarity in the Central and Southern regions, but they have their own peculiarities too. Til' this day I still find it iffy they call someone named "Diễm" as "Yỉm". Unless you have seen the correct way to spell those words before, you can't say for sure. Even now as a working adult I find myself referring to the dictionary to make sure my accent doesn't embarrass me in official emails.
In a perfect world, we can have one single Vietnamese accent that aims to pronoun all these words true to the intended way of the alphabet, but it isn't practical. That being said, one can get pretty far in Vietnamese when encountering new words.
Yeah, and because the "common" way of pronouncing these words/letters have become so entrenched in our minds, it often feels pretentious to hear people actively try to pronounce words in a way that they feel is "correct", for example trying to emphasize the "strength" of the tr/s/gi sounds as opposed to ch/x/d.
Not so much in terms of meaning but in terms of pronunciation, sometimes you also need to read ahead in English to know how a certain word is pronounced. For example:
"I read a book yesterday."
and
"I read a book every night."
Depending on the context that follows, "read" is pronounced differently. The same thing happens for "present" and "record". Admittedly, these are exceptions to the rule.
