#42The Australian-Vietnamese continuum is well-explained by Australia being the geographically nearest region which can supply native English language teachers to English language learners in Vietnam, rather than by any intrinsic phonetic resemblance between Vietnamese and Australian English.

#43Since our own accents generally sound neutral to ourselves, I would love someone to make an accent-doubler - take the differences between two accents and expand them, so an Australian can hear what they sound like to an American, or vice-versa

#44BERT still making headlines in 2025, you love to see it.

#45The source code for this is unminified and very readable if you’re one of the rare few who has interesting latent spaces to visualize. https://accent-explorer.boldvoice.com/script.js?v=5
could you explain what it means for someone to “have interesting latent spaces”? curious how you’re using that metaphor here

#46Why do the voices all sound so similar? I'm not talking about accent, I'm talking about the pitch, timbre, and other qualities of the voice themselves. For instance, all the phrases I heard sounded like they were said by a medium-set 45 year old man. Nothing from kids, the elderly, or people with lower / higher-pitch voices. I assume this expected from the dataset for some reason, but am really curious about that reason. Did they just get many people with similar vocal qualities but wide ranges of accents?

From the article:
> By clicking or tapping on a point, you will hear a standardized version of the corresponding recording. The reason for voice standardization is two-fold: first, it anonymizes the speaker in the original recordings in order to protect their privacy. Second, it allows us to hear each accent projected onto a neutral voice, making it easier to hear the accent differences and ignore extraneous differences like gender, recording quality, and background noise. However, there is no free lunch: it does not perfectly preserve the source accent and introduces some audible phonetic artifacts.
> This voice standardization model is an in-house accent-preserving voice conversion model.

#48This is fascinating in theory, but I'm confused in practice.
When I play the different recordings, which I understand have the accent "re-applied" to a neutral voice, it's very difficult to hear any actual differences in vowels, let alone prosody. Like if I click on "French", there's something vaguely different, but it's quite... off. It certainly doesn't sound like any native French speaker I've ever heard. And after all, a huge part of accent is prosody. So I'm not sure what vocal features they're considering as "accent"?
I'm also curious what the three dimensions are supposed to represent? Obviously there's no objective answer, but if they've listened to all the samples, surely they could explain the main constrasting features each dimension seems to encode?

#49I'm deaf. Something close to standard Canadian English is my native language. Most native English speakers claim my speech is unmarked but I think they're being polite; it's slightly marked as unusual and some with a good ear can easily tell it's because of hearing loss.
Using the accent guesser, I have a Swedish accent. Danish and Australian English follow as a close tie.
It's not just the AI. Non-native speakers of English often think I have a foreign accent, too. Often they guess at English or Australian. Like I must have been born there and moved here when I was younger, right? I've also been asked if I was Scandinavian.
Interestingly I've noticed that native speakers never make this mistake. They sometimes recognize that I have a speech impediment but there's something about how I talk that is recognized with confidence as a native accent. That leads me to the (probably obvious) inference that whatever it is that non-native speakers use to judge accent and competency, it is different from what native speakers use. I'm guessing in my case, phrase-length tone contour. (Which I can sort of hear, and presumably reproduce well, even if I have trouble with the consonants.)
AI also really has trouble with transcribing my speech. I noticed that as early as the '90s with early speech recognition software. It was completely unusable. Even now AI transcription has much more trouble with me than with most people. Yet aside from a habit of sometimes mumbling, I'm told I speak quite clearly, by humans.
Hearing different things, as it were.

#50Fascinating work — especially how geography and history influence accent clustering more than language families. Brilliant visualization!
