### Overview

Sanas **Language Translation**( **LT**) enables real-time, bidirectional speech-to-speech translation for seamless multilingual conversations. Using an AI-powered audio pipeline, LT captures speech in one language, translates it, and delivers the output in the recipient's preferred language—all with near-real-time latency and full contextual accuracy.

#### How it works

1. **Speak** — The agent or customer speaks naturally in their preferred languages configured at the Sanas application.

2. **Translate** — Our AI models capture the speech, translate it in real-time, and synthesize a voice that closely matches the original speaker.

3. **Listen** — The recipient hears the translated speech in their language within seconds.

Translation begins within an average of 3 seconds, and voice synthesis occurs within the first second of the call.

### Key features

- **Near-real-time latency** — Sanas starts translating in near-real-time ( _with an average latency of 3 seconds_) during a live call, keeping your multilingual conversations engaging and naturally flowing.

- **Enterprise readiness**— Deployable via the [Sanas Desktop application](https://help.sanas.ai/portalv3/docs/sanas-application-overview) and managed through the [Portal](https://help.sanas.ai/portalv3/docs/sanas-portal), ensuring seamless enterprise integration.

- **Privacy-first architecture**— No conversation data or voice samples are stored beyond the duration of your call, ensuring complete data privacy.

- **Custom glossary support**— Configure up to 100 custom terms, brand names, and proper nouns to bypass translation. Glossary terms configured in the Sanas Portal are automatically applied during live calls.

- **Translation captioning**— Agents can view source and translated transcriptions for the entire conversation in real-time. Transcription data is removed when LT is turned off.
