I have an Indian accent, so I'm doubting the net positive of recording Loom videos — what are your thoughts?
I'd say there's an even bigger net positive, frankly. If you want to get more articulate in English, the best way is to just talk a lot in English — there's someone who went from nothing to French fluency in under a month just by recording himself trying to speak French for an hour every day; the first videos were rough and hard to understand, but by the end he was a solid, clear speaker who could chain words together well. Your early Looms won't get you much in results, but Looms are free (especially with a custom-DM approach), so there's not much of a downside to just starting.
