Next highest was Portuguese at 31.4 per cent, while Russian and Hungarian were the next most commonly translated languages.
The figures were released by the Minister of Health, Social Services and Public Safety following a question to his department by David McIlveen, MLA for North Antrim.
The NIHSCIS has 92 interpreters currently registered with 38 Lithuanian, 20 Portuguese, 20 Russian and 14 Hungarian translators.
A spokesperson for the Southern Health and Social Care Trust said: “The Southern Trust has one of the largest ethnic minority populations in Northern Ireland and our overall population is projected to grow by 13.5% by 2020. Our ethnic minority population is also likely to increase significantly by 2020 as birth rates continue to keep growing.
“Provision of language assistance is a legal requirement for public sector organisations and as an essential part of providing safe, high quality care to all patients and clients, we are committed to ensuring everyone is given equal access to information about services in a format they can understand.
“With access to interpreters for 36 minority ethnic languages, the Trust provides interpreting services on request to help patients and clients and staff to communicate when using services.
“These interpreters are provided and funded regionally through the Northern Ireland Health and Social Care Interpreting Service.”
