For example, I thought I had a decent handle on Scottish accents. Turns out I don’t, just that all the Scottish people I worked with were anglicising their accents. I only heard their natural accents after we had a few pints. Now I’m working with several Scottish people who don’t change their accent and it is hard. I’m thinking I probably have to watch a few seasons of Outlander to get used to it.
There’s nothing “natural” about any accent. How difficult was the Boston accent the first time you heard it? I needed subtitles for sure. Then I watched several movies set in Boston (Good Will Hunting, The Departed, The Town) and it’s understandable now.
All this to say - you need familiarity to understand and you need to put in effort to gain familiarity. That’s fairly uncontroversial.
Here’s the controversial part - people will put in the effort to understand the accents and dialects of people from Scotland, Ireland, Australia, New Zealand, Canada, America. But if it’s an accent/dialect from India, they say some racist shit about the brown people being unable to speak English.
So yes “Strong Indian accents are very difficult” for you. And now you know why.
