Production-ready Catalan to Spanish translation API

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

Catalan and Spanish both belong to the Indo-European > Romance > Western Romance family, so cognates and shared structure carry over cleanly into the translated Spanish output.

Soniox preserves formatting in the translated transcript, including names, numbers, addresses, IDs, and domain-specific terms.

Real-time Catalan to Spanish translation

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

Frequently asked questions

How do I translate Catalan to Spanish with the API?

Add a translation block to your real-time request with source_language "ca" and target_language "es". Soniox transcribes Catalan and streams the Spanish translation over the same WebSocket.

Is Catalan to Spanish translation real-time?

Yes. Soniox streams Spanish while Catalan is still being spoken, so meaning arrives mid-sentence instead of after the sentence ends.

What about translating Spanish to Catalan?

That direction is supported too. See the Spanish to Catalan page, or use two-way translation to run both directions in one session.

Catalan and Spanish are both Indo-European > Romance > Western Romance — does that affect quality?

Shared family structure and cognates generally help. Soniox uses the same model for every pair, so quality stays consistent whether the languages are closely related or not.

Does Soniox handle Catalan dialects and accents?

Yes. Soniox handles Catalan dialects like Central Catalan, Valencian, and Balearic in a single model, so Spanish translation stays accurate across regions.

Which other providers support Catalan to Spanish?

Based on their public docs, OpenAI, Google, Azure, and Speechmatics list both Catalan and Spanish for real-time translation. Soniox is the only one that also supports two-way live translation across 60+ languages.

How fast is Catalan to Spanish translation?

Soniox streams Spanish as Catalan is being spoken, with ultra-low latency. Translation arrives before the sentence ends.
