#kolkatan

Note: I'm not a linguist, I can only speak through my experience with people from these regions. And I'm talking about the accent not dialect. Alsoooo accents can vary from individual to individual.

Standard Bangla/how I think it should be pronounced: আমার তোমার উপর বিশ্বাস শেষ হয়ে গেছে (Āmār tomār upor biśśās śeṣ ho'e gæche)

Medinipuria: আমার তোমার উপর বিস্সাস সেস হয়ে গেছে (āmār tomār upor bissās ses ho'e gæche).

Kolkatan: আমার তোমার উপর বিশ্বাশ শেশ হয়ে গেছে (āmār tomār upor biśśāś śeś ho'e gæche)

Dhakaiya: আমার তোমার উপর বিশ্বাশ শেশ হয়ে গেসে (āmār tomār upor biśśāś śeś ho'e gæse)

Some general trends:

Speakers from Medinipur region will tend to double the consonants if there is a half 'r' or reph after it. পরতে becomes পত্তে, করতে becomes কত্তে, কর্তা becomes কত্তা. All 's' sounds are pronounced s. No sh, i.e স শ and ষ are all pronounced like স (s). More usage of ô sound than o.

Speakers from Kolkata too sometimes tend to double consonants. All s sounds are pronounced sh. স শ and ষ are pronounced শ (ś).

Speakers from Eastern and East-Central part of Bengal/Bangladesh and adjoining regions tend to pronounce ছ (ch) as স (s). করছে becomes করসে. Also ও (o) is sometimes pronounced like উ (u). The s sounds are all generally pronounced like শ (ś), much like Kolkatans. I've also noticed জ (j) being pronounced as জ় (z).

I'm not a Kolkatan, so don't expect me to speak with a mouthful of rôsogolla. I'm from the Medinipur region and so the intonation might be slightly different.

My native dialect only has 's' and no 'sh'. So even though I've grown up speaking only standard bangla, pronouncing শেষ as 'shesh' feels unnatural to me. 'ses' is much easier to pronounce.

Since I learned the Bangla script late, I tend to differentiate the three 's' sounds and pronounce them differently. So বিশ্বাস is 'bishshas' and neither Kolkatan 'bishshash' nor Medinipuria 'bissas'. I do things my way xD

Also, the vowel harmony oof... It's hard to know when it's ô and when o :')

I wasn't brought up in Bengal or a Bengali speaking neighborhood, hence I don't have that typical accent and end up sounding, as my teacher put it, "so english english" lol. I do try my best to speak with a mouthful of mishti though.

Because I learned late, I am a slow reader. Adding to my Bangla sounding like that of a non-native's.
