Production-ready Hindi to Persian translation API

Real Hindi speech includes accents, regional dialects, code switching, and domain-specific vocabulary. Soniox recognizes it in a single model and streams Persian while the speaker is still talking.

Hindi (Indo-European > Indo-Aryan > Central) and Persian (Indo-European > Iranian > Western Iranian) come from different language families, so word order and morphology differ. Soniox reorders meaning in-stream instead of word by word.

Hindi is written in Devanagari and Persian in Arabic, so Soniox emits correctly scripted Persian text. Right-to-left output is handled directly in the token stream.

Real-time Hindi to Persian translation

Soniox streams the Hindi transcript and the Persian translation on the same connection, word by word, so meaning lands while the speaker is still talking.

Frequently asked questions

How do I translate Hindi to Persian with the API?
Add a translation block to your real-time request with source_language "hi" and target_language "fa". Soniox transcribes Hindi and streams the Persian translation over the same WebSocket.
Is Hindi to Persian translation real-time?
Yes. Soniox streams Persian while Hindi is still being spoken, so meaning arrives mid-sentence instead of after the sentence ends.
What about translating Persian to Hindi?
That direction is supported too. See the Persian to Hindi page, or use two-way translation to run both directions in one session.
Does Soniox handle Devanagari to Arabic output?
Yes. Soniox outputs correctly scripted Persian text in Arabic, including right-to-left rendering, directly in the token stream.
Does Soniox handle Hindi dialects and accents?
Yes. Soniox handles Hindi dialects like Khariboli, Braj Bhasha, and Awadhi in a single model, so Persian translation stays accurate across regions.
Which other providers support Hindi to Persian?
Based on their public docs, OpenAI and Azure list both Hindi and Persian for real-time translation. Soniox is the only one that also supports two-way live translation across 60+ languages.
How fast is Hindi to Persian translation?
Soniox streams Persian as Hindi is being spoken, with ultra-low latency. Translation arrives before the sentence ends.
