Sylheti translation services
Sylheti has 11 million native speakers but no support from any major machine translation engine, outputs default to Bengali, which misses Sylheti-specific vocabulary, tonal features, and phonological patterns that make the two languages mutually unintelligible in many contexts.
The additional complexity of a distinct historical script (Sylheti Nagari) alongside modern Bengali script usage means vendors must source linguists who understand both writing systems. MoniSa confirms reviewer path, sourcing model, and delivery timing in the project brief.
Rare-language TEP surge is the closest match for this language: comparable scope, script handling, and review depth, with proof you can verify.

Buyer need
When Sylheti translation needs more than a language name.
For Sylheti, the buyer risk is script choice, orthography control, and reviewer fit, not generic translation quality. MoniSa confirms script, dialect, reviewer, and service fit against the brief before production begins.
Service answer
Sylheti translation depends on audience, script, and review fit.
Sylheti is an Indo-Aryan language in the Bengali-Assamese branch, spoken by approximately 11 million people primarily in Bangladesh's Sylhet division and northeastern India. Despite its speaker population, Sylheti is frequently misclassified as a dialect of Bengali — a categorization that obscures significant phonological and lexical differences that impede mutual intelligibility. The Sylheti Nagari script is a historically independent writing system with 28 consonants and 7 vowels, though modern usage has largely shifted to Bengali script. The UK hosts the largest Sylheti diaspora, with over 500,000 British Bangladeshis of Sylheti origin concentrated in East London. No major MT engine supports Sylheti as a distinct language, all default to Bengali, producing output that misses Sylheti-specific vocabulary and the tonal features absent from Standard Bengali.
MoniSa confirms the reviewer path, review depth, and delivery timing for Sylheti in the project brief. Every assigned linguist is verified for the variety and domain your project needs. We publish coverage and review depth, not the routes we recruit through.

Our Sylheti translation process
How MoniSa QA works for Sylheti translation.
All Sylheti work follows MoniSa's 3-layer review model: translator (native Sylheti speaker, domain-matched, verified to produce Sylheti rather than Bengali output), editor (bilingual accuracy and terminology adherence with Bengali-interference screening), proofreader or community validator (cultural and dialectal review, particularly for diaspora-targeted content). Review depth is set in scope rather than assumed from the language name alone.
-
Step 1
Scope and match
Two decisions come first: that the work is genuinely Sylheti rather than Standard Bengali, and which script the output uses. Sylheti was historically written in Sylheti Nagri, but most modern material now uses the Bengali script, so we confirm the writing system, the dialect, and the audience before assignment. This matters because procurement systems often list only "Bengali" and quietly fold Sylheti under it.
-
Step 2
Review the risky parts first
Translation, editing, and proofreading stay tied to that scope, with native Sylheti speakers rather than Bengali linguists reassigned to the work. The defining review pass is interference: editors confirm that Standard Bengali vocabulary and grammar have not displaced Sylheti-specific terms, which happens easily when a writer drifts toward the prestige standard. Meaning and terminology are checked at the same time.
-
Step 3
Send files with context attached
You receive the translated files with the review notes a buyer needs to accept the work. Where the historical Sylheti Nagri script is used, rendering is confirmed before handoff, and any later correction keeps the script and dialect decisions attached to the change.

Live interpreting
If a Sylheti conversation needs an interpreter.
Sylheti work reaches MoniSa mainly as written material, and a spoken request is the exception rather than the rule. When one does arrive it is scoped as its own piece of work rather than folded into a translation quote, because the unit, the screening and the delivery are all different.
Interpreting in Sylheti means a qualified interpreter renders a live conversation between Sylheti and another language, delivered in one of three ways: on an audio call, over a video link, or in the room. It is not translation. Translation produces a written deliverable and is quoted on volume, file type and review depth; interpreting is a live event with a date, a duration and a setting, and is booked as time. That is also how the two appear on a quote, with content on one line and time on the other, so a matter that needs both is scoped as two pieces of work rather than one. MoniSa sources and screens interpreters across 300+ languages and 4,500+ dialects from its network of 110,000+ verified language specialists, and operates under ISO 9001 and ISO 27001 certification.
Screening for a Sylheti session starts with the variety the speaker actually uses, because a near match is not a match once a conversation is under way. The interpreter is then checked in the working pair and screened against the setting the session comes from, so a clinical encounter, a legal proceeding and a school meeting count as separate qualifications rather than one. Everyone assigned signs the confidentiality agreement before receiving access, and named backup coverage is recorded alongside the primary assignment. What MoniSa publishes is the coverage and the screening, never the routes it recruits through.
Audio line
Over the phone
An audio line connects faster than any other modality, which makes it the right route for short, unscheduled exchanges such as an intake call, a benefits query, or an appointment booking, where nothing visual carries meaning.
Over-the-phone interpretationVideo link
Over a video link
A live video link is used when a document, a device, a physical examination or a signed language is part of the conversation, and when the people in the room and the interpreter need to see each other without anyone travelling.
Video remote interpretingClinical setting
In a patient encounter
A clinical encounter adds a credential requirement and a domain screen on top of the language check, because a summarised symptom or a softened instruction changes the care that follows.

Buyer questions
Answers in writing, before you ask for a call.
The questions buyers send before a scope conversation, answered on the page rather than in a meeting. Take them to your team, then send us the one we did not answer.
How do you source Sylheti translators?
MoniSa confirms reviewer path, sourcing model, and delivery timing in the project brief. Linguists are verified native Sylheti speakers, not Bengali linguists reassigned to Sylheti work.
Is Sylheti different enough from Bengali to need separate translation?
Yes. Sylheti and Standard Bengali differ in phonology, vocabulary, and grammatical structures to the point of impaired mutual intelligibility. Bengali translations are not understood by many Sylheti-primary speakers, especially older community members with limited formal education in Standard Bengali. Treating Sylheti as Bengali is a classification error, not a localization shortcut.
How long does sourcing take for Sylheti?
Timing is confirmed after project brief. Buyers get the likely sourcing path, service fit, and related proof rather than a delivery promise.
What quality metrics do you report?
Project-scoped quality data stays inside the linked case study. On live work, review depth, reporting, and acceptance logic are confirmed in scope before production starts.
Do I need Sylheti interpreting or Sylheti translation?
Translation is written: a document, a record, a subtitle track, delivered as content and quoted on volume and review depth. Interpreting is spoken: a live conversation on the phone, over video or in the room, booked as time with a date attached. A hearing, an appointment or a call needs an interpreter; a form, a notice or a record needs a translation, and most matters need both. MoniSa scopes them separately, because the sourcing, the screening and the unit of work differ, and confirms which one the brief actually needs before quoting.
What happens if you cannot staff one of my language pairs?
You are told before a date is agreed, not after. Coverage is reported pair by pair as staffed today or needing a recruitment window, with the window stated — in writing, while the scope is still being agreed. Nobody new goes onto live work until a pilot batch has been reviewed and signed off. A coverage claim you cannot check before signing is not coverage.
