Transcription + translation through a single stream

Swahili translation is built on top of Soniox Speech-to-Text API. Every spoken word is transcribed, and translation streams mid-sentence and both arrive together in a single labeled token stream.

Turn it on by adding a translation block to your request. Translation runs on the same WebSocket and the same model. Translated tokens come back interleaved with transcripts, with no extra round trip.

Frequently asked questions

Does Soniox translate Swahili in real time?

Yes. Soniox streams Swahili translation while speech is still happening, so users see or hear meaning immediately instead of waiting for the sentence to end.

What language pairs are supported for Swahili?

Soniox supports translation between Swahili and any of 60+ supported languages — 3,600 language pairs in total. Both Swahili as the source and Swahili as the target are supported.

How does two-way Swahili translation work?

Two-way translation lets both sides of a conversation speak in their own language and hear the other side in theirs. A Swahili speaker can talk in Swahili while the other party hears their own language in real time, and vice versa.

Does Soniox handle dialects and accents in Swahili?

Yes. Soniox handles Swahili dialects like Kiunguja, Kimvita, and Kiamu in a single model, along with accents and language switching, so live translation stays accurate across regions and registers.

Can Soniox translate names, numbers, and domain terms in Swahili?

Yes. Soniox preserves the details that matter — names, phone numbers, emails, IDs, addresses, verification codes, and domain-specific terminology — in both the Swahili transcript and the translated output.

Which other providers support live Swahili translation?

Based on their public docs, OpenAI and Azure list Swahili as a supported source language for real-time translation. Soniox is the only one of them that also supports two-way live translation across 60+ languages.

How fast is Swahili translation?

Soniox streams translated text as Swahili is being spoken, with ultra-low latency. Translation arrives before the sentence ends, rather than after long caption delays.

What can I build with Swahili translation?

Common use cases include multilingual voice agents, live interpreters, multilingual meetings, customer support and contact centers, real-time translated captions and subtitles, and accessibility and communication tools — all with Swahili as a source or target.
