Assamese Sa palibot sa Speech

Sa palibot sa Aïn el Aïd. Assamese Text-to-speech

Assamese shares almost the same script as Bengali, and that resemblance is exactly why generic Bengali text-to-speech mangles it: Assamese uses distinct letters — its own ৰ (ra) and ৱ (va) — and, far more importantly, it has a velar fricative sound written where Bengali would read an 's' or 'sh', so the Assamese letters শ, ষ and স are commonly pronounced as a throaty /x/ that exists in no other major Indian language. A voice that does not know this rule will read Assamese with Bengali sibilants and sound immediately wrong to any native listener. Beyond that signature /x/, Assamese retains the eastern Indo-Aryan rounded inherent vowel, fuses consonants into conjunct ligatures the renderer must decompose, and marks nasalization. It has also simplified some consonant contrasts relative to its neighbours, so faithful synthesis is as much about not over-articulating as about adding sounds. Standard Assamese is centred on the varieties used in Guwahati and upper Assam. Demand comes from Assam's state government and education services, Assamese news and film, and accessibility for a speaker community that is regionally concentrated and underserved by mainstream tools.
