Hindi to Urdu speech translation API
Stream Hindi (हिन्दी) speech and get Urdu (اردو) back in real time. One WebSocket, ISO codes hi to ur, and ultra-low latency for voice agents and live apps.
Trusted by teams building global voice products
Production-ready Hindi to Urdu translation API
Real Hindi speech includes accents, regional dialects, code switching, and domain-specific vocabulary. Soniox recognizes it in a single model and streams Urdu while the speaker is still talking.
Hindi and Urdu both belong to the Indo-European > Indo-Aryan > Central family, so cognates and shared structure carry over cleanly into the translated Urdu output.
Hindi is written in Devanagari and Urdu in Arabic, so Soniox emits correctly scripted Urdu text. Right-to-left output is handled directly in the token stream.

}Hindi and Urdu through a single stream
Hindi to Urdu translation is built on top of Soniox Speech-to-Text API. Every spoken word is transcribed, and Urdu translation streams mid-sentence in the same labeled token stream.
Turn it on by adding a translation block with source_language: "hi" and target_language: "ur". It runs on the same WebSocket and the same model, with no extra round trip.
