Production-ready Hindi to Thai translation API

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

Hindi (Indo-European > Indo-Aryan > Central) and Thai (Kra-Dai > Tai) 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 Thai in Thai, so Soniox emits correctly scripted Thai text.

Real-time Hindi to Thai translation

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