This really isn't surprising. Look at Google Home and Alexa. When they first came out, if you weren't a white male from the west coast... the accuracy of translating commands dropped DRAMATICALLY. Because it was programmed, designed and tested by majority of white tech bros in SF/Seattle. They've gotten a lot better over the last 5+ years. But I think you'll see OpenAI take this route.
But that's ok. They have to start somewhere. Once they get the model working really well for one language they can expand into similar ones with relatively little work. The more different the language, the more hard work and "local input" (ex: natives of the language) will be required for adaptation. But the basic text translations are still already way better than they used to be.
It's a shame, because that means I can use stuff that I can't recommend to people around me
Multilingual UX is an interesting painpoint, I had to change the language of my account to English so I could use some early Bard version, even though It was perfectly able to understand and answer in Spanish
(accents sure)
(Siri's original speech recognition was a combination of Swiss-Germans and people from Boston.)
And it certainly wouldn't be tested by them either way. Companies know how to hire QA contractors.
Even beside that though -- it's patently ridiculous to suggest that these devices would perform worse with an Asian man who speaks fluent English and was born in California. Or a white woman from the Bay Area. Or a white man from Massachusetts.
You kind of have a point about tech being the product of the culture in which it was produced, but the needless exaggerated references to gender and race undermine it.
But for conversation, you can’t speak Mandarin without using proper tones because you simply won’t be understood.
You can be perfectly understood if you don't speak broadcast Chinese. There are plenty of heavy accents to deal with anyways. Like Beijing 儿化 or the inability of southerners to pronounce sh very differently from s.
What's strange to me is that, as far as I know, "plátano" is only commonly used in Spain, but the accent of the AI voice didn't sound like it's from Spain. It sounds more like an American who speaks Spanish as a second language, and those folks typically speak some Mexican dialect of Spanish.
The wiktionary page for "plátano" has a map illustrating how various Spanish-speaking countries refer to the banana.

My principal association with plátano is plaintain, personally, but I am not a Spanish speaker.
Plátano is commonly used for banana in Mexico, just bought some at a Soriana this weekend.
And note that understanding broken language is a skill you have to train. If you aren't used to it then it is impossible to understand what they say. You might not have been in that situation if you are an English speaker since you are so used to broken English, but it happens a lot for others.
The Italian sounded good to me.
The first (and imo the main) hurdle is not reproduction, but just learning to hear the correct sounds. If you don't speak Hindi and are a native English speaker, this [1] is a good example. You can only work on nailing those consonants when they become as distinct to your ear as cUp and cAp are in English.
We can get by by falling back to context (it's unlikely someone would ask for a "shit of paper"!), but it's impossible to confidently reproduce the sounds unless they are already completely distinct in our heads/ears.
That's because we think we hear things as they are, but it's an illusion. Cup/cap distinction is as subtle to an Eastern European as Hindi consonants or Mandarin tones are to English speakers, because the set of meaningful sounds distinctions differs between languages. Relearning the phonetic system requires dedicated work (minimal pairs is one option) and learning enough phonetics to have the vocabulary to discuss sounds as they are. It's not enough to just give feedback.
interestingly, i think this isn't always true -- i was able to coach my native-spanish-speaking wife to correctly pronounce "v" vs "b" (both are just "b" in spanish, or at least her dialect) before she could hear the difference; later on she was developed the ability to hear it.
Even styles of thought might be different in other languages, so I don't say that lightly... (stay strong, Sapir-Wharf, stay strong ;)
Seems like these would be similar.
