The paper presented by him is titled "Cross Linguistics Phonological Features of the Languages in the Brahmaputra Vally: An Areal Study" and analyses the phonological properties of some primary languages spoken in the Brahmaputra Valley of Assam and focusing on consonants and vowels, nasalization, vowel length and tones.

The languages considered by Dr. Moral in this study include grouped A, B and C, with Group A comprising of Boro, Garo, Rabha, Tiwa (Or Lalung, Tintekiyan Koch, Koch, Deuri and all BG languages; Group B comprises Mising and Group C contains Asamiya.

In conclusion, this study focuses on the elements of different languages of the Brahmaputra Valley belonging to the Tibeto-Burman, Indo-Aryan, Siamese-Chinese and some Dravidian and Munda languages highlighting their cross-linguistic phonological features.

In the discussion that followed the session, chaired by Dr. P. P. Giridhar, the following points were raised. Prof. Hans Hock, questioned that whether the concept of glottal stops developing from moving tones did have relevance in his study in this area as it happened in Danish; for which Prof Moral cited the example of Angami in Nagaland. Prof. Sisir Kumar Sinha's made an observation that even Bangla has the phenomenon of 'bidya' becoming 'bidda' and 'goswami' becoming 'gossami' is in fact assimilation.
