I am curious - why UMAP not t-SNE? (See https://pair-code.github.io/understanding-umap/) When I saw the vis, there is a a collection of lines, which look as an artifact. t-SNE (typically) gives more "organic" results of blobs, provided you set perplexity high enough.

Also, while I admire examples of instances, it would be interesting to the map or original laguages - which is close to which, in terms of their English accents.
