Temne Translation Services

Temne is the language of northern Sierra Leone, first language of the country's largest ethnic group at 31.4 percent of the population in the 2015 census. Prism Language Solutions supplies Temne interpreters for hearings, USCIS interviews and medical appointments, and certified English translation of Temne statements, affidavits and recordings. Sierra Leone issues its certificates in English, so most Temne callers need no document translation at all, and we say that on the first call.

The Temne heartland is the north: Bombali and Tonkolili in the Northern Province, Port Loko, Kambia and Karene in the North West, with Makeni as the largest city. That geography matters at booking, because Sierra Leone's other large language, Mende, belongs to the south and east, and the two are not related. A request that says only Sierra Leone leaves a scheduler guessing between them.

Most working-age Sierra Leoneans move between English, Krio and their home language without thinking about it, which conceals who actually needs an interpreter. The person who does is usually older, rural, or recently arrived. Getting that judgement right is most of the value of this page.

What a Temne File Needs Translated When Records Are English

The National Civil Registration Authority, created under the National Civil Registration Act 2016, registers births, deaths, marriages and divorces, and it issues in English. So does the passport office, so do the schools. USCIS asks under 8 CFR 103.2(b)(3) for a certified English translation of foreign-language documents, and an English Sierra Leonean certificate is not one. Paying to have it translated produces a second English version of a document the officer already holds, which helps nobody.

• Recorded statements and voice messages, transcribed and translated side by side
• Affidavits and declarations given orally in Temne and written down by someone else
• Handwritten letters from family in the north, often mixing Temne with Krio
• Interview and hearing recordings needed as a transcript for a filing
• Certificates from the National Civil Registration Authority, which are already in English and need nothing

Booking a Temne Interpreter Rather Than Krio or English

Krio is the common language of nearly the whole country, and it is the reason Temne appointments get mis-staffed. A Krio interpreter can hold a conversation with almost any Sierra Leonean, which looks like a solution until the questions become precise. An older woman from a Tonkolili village will answer in Krio and then reach for Temne at the moment the answer actually matters.

The failure we watch for is drift. An interpreter who starts in Temne and slides into Krio to keep the pace up has changed the language of the record halfway through, and nobody in the room notices. We brief ours to stay in Temne for the whole appointment and to say so if the speaker moves. For a hospital, the provider taking federal health funding owes the patient a qualified interpreter at no charge under 45 CFR 92.201, which is worth repeating to a scheduler who suggests a bilingual son. See medical interpreting.

Temne Dialects and the Northern District an Interpreter Should Match

Most Temne varieties travel well. Yoni, Bombali, Western and Western Konike speakers follow one another without much friction, so a single interpreter usually covers a courtroom or a clinic. Eastern Konike is the exception and other Temne speakers can struggle with it, so we ask the chiefdom and not just the country before we assign.

No US state runs a court certification examination in Temne, so a court works from an interpreter qualified another way and decides what it will accept for the proceeding. Tell us the court, the type of hearing and the speaker's home district, and we confirm the arrangement in writing beforehand rather than on the morning. Prism is hired directly by courts, firms and hospitals as a private agency; we hold no court appointment or vendor listing. See court interpreting.

Temne Affidavits and Secondary Evidence for an Unregistered Birth Record

Civil registration in Sierra Leone was reorganized only in 2016, and an adult born in the 1980s or 1990s, through the years of the war, cannot be assumed to have a registered birth. What families often hold instead is a certificate issued recently on the basis of a late declaration, which is a different document with a different date on it, and it should be translated and described as that rather than presented as a contemporaneous record.

Certified Temne Transcription of Recordings, and Names on the Page

Audio is the most common Temne job we see. We transcribe the Temne, set the English beside it with time stamps, mark inaudible passages rather than filling them, and show where the speaker crosses into Krio or English. That layout matters when somebody is going to play the recording while reading the translation.

Names need a decision rather than a guess. Written Temne uses letters and marks that US forms strip out, and Sierra Leonean naming adds its own variation, so Kamara, Conteh, Bangura, Sesay, Turay and Koroma turn up spelled several ways across a passport, a school paper and a handwritten letter. We set the primary spelling to the travel document, reproduce the source spelling as written, and list the variants in a translator note so the file explains itself. See transcription and certified translation.
