Transliteration and Translation — Bhashini

What does the Transliteration and Translation API do?

The Transliteration and Translation API converts text between English and supported Indian languages. It supports two operations:

• Transliteration — converts text character-by-character from one script to another (e.g., English letters → Hindi script), preserving pronunciation.
• Translation — converts the meaning of text from one language to another.

This service is provided by Bhashini on the ULI Platform.

Who can use this API?

Lenders onboarded to the ULI Platform who have subscribed to the Transliteration service on the Dev Portal. Separate subscriptions are required for Sandbox and Production environments.
