This is so cool. Real-time accent feedback is something language learners have never had throughout all of human history, until now.

Along similar lines, it would be useful to map a speaker's vowels in vowel-space (and likewise for consonants?) to compare native to non-native speakers.

I can't wait until something like this is available for Japanese.

The approach in the article is roughly equivalent to having someone listen to you speak and then repeating back in their own voice so you can attempt to copy their accent. Certainly nice to have available on demand without needing to coordinate schedules with another human.

A good accent coach would be able to do much better by identifying exactly how you're pronouncing things differently, telling you what you should be doing in your mouth to change that, and giving you targeted exercises to practice.

Presumably a model that predicts the position of various articulators at every timestamp in a recording could be useful for something similar.

.. unless they had access to a native speaker and/or vocal coach? While an automated Henry Higgins is nifty, it's not something humans haven't been able to do themselves.

Native speakers are less helpful at this than you might think. Speech coaches are absolutely the way to go, but they're outside the price range for most people ($200+/hr for a good coach). BoldVoice gives coach-level feedback and instruction at a price point that everyone can access, on demand.

That's a fascinating idea! Definitely something to try out for our team. We actively and continuously do all sorts of experiments with our machine learning models to be able to extract the most useful insights. We will definitely share if we find something useful here.

Do you have a source for this? It doesn't seem plausible to me, but I'm not an expert.
