[8] Western Vaṅga is spoken across the Bangladeshi divisions of Mymensingh, Dhaka, and Barisal.

The Southeastern group is spoken across the modern Bangladeshi divisions of Mymensingh, Dhaka, Barisal, and Khulna, as well as the Greater Noakhali region of the Chittagong division and eastern parts of the 24 Parganas district in West Bengal.

[16] Group IV or "South East Bengali" is spoken in the Chittagong Division, notably excluding the Greater Comilla region.

[17] The Comilla District and Tripura state of India, the Bengalis in the latter chiefly being migrants from the former, sit at the confluence of all the major groupings and thus the speech of this region shares features with all the major groups classified by Haldar.

Metathesis also occurs in the case of consonant conjuncts which were once pronounced with [i̯] as a component even if they do not contain ‍্য jôphôla itself, such as ক্ষ (ISO-15919: kṣa), whose value in earlier Bengali was [kːʰi̯].

There is also a tendency to hypercorrect, leading to the frequent diphthongisation of vowels with [i̯] if they precede any consonant cluster, even when there is no etymological basis to do so.

However, Animesh K. Pal, a native speaker of Eastern Bengali from Narayanganj, disputed this claim, instead describing the deaspiration as leading to the development of tones.

Tone continues to exist in words even if they are not part of a near-identical pair that requires it for the sake of contrast.
