How it works

Live in three steps.

Pick your languages

Choose what you speak and what they hear. 24 languages, any pairing, and you can switch sides mid-call.

Connect any way

Send a one-tap room link, type any phone number and we dial it, or open WhatsApp & WeChat on the Concierge handset.

Just talk

Speak naturally. They hear you in their language, in your own cloned voice, with sub-second latency and live captions.

Beyond calls

Works where you already chat.

On the Concierge handset, SimulSpeak translates right inside WhatsApp and WeChat, voice messages, calls and texts, both directions. Your contact sends Mandarin; you read and hear it in Hungarian, and reply in your own voice.

Everything it does

One platform, every way you talk.

Real-time translated calls

Streaming speech to translation to speech in your own cloned voice — sub-second, either direction, switchable mid-call. Over the phone or a one-tap browser room link.

In-person translator

Two people, one phone, face to face — it listens and speaks each side's language back and forth. No second device, no interpreter.

WhatsApp & WeChat, in place

Texts, voice notes and in-app calls translated both ways, right inside the chat you already use — nothing to copy or paste.

Voice messages in your voice

Hear their voice note in your language, and send yours translated and spoken back in your own cloned voice.

Cloned-voice AI agent

Makes and answers calls and replies to WhatsApp & WeChat on its own, grounded in your knowledge base, handing off to you when it is unsure.

Smart call handling

Auto-decline unwanted calls and reply to the caller in their language — or let the agent pick up and translate the whole call live.

24 languages, any pairing

Hungarian, Chinese, Spanish, English, German, Arabic, Korean and more — translated in either direction and switchable mid-conversation.

One private dashboard

Every call recorded with transcripts, live captions and usage in one place. EU infrastructure, never sold or used to train models.

Worldwide

Calls happening everywhere, right now.

Budapest to Shanghai, New York to Lagos, São Paulo to Sydney, SimulSpeak runs on in-region infrastructure so every leg stays fast, wherever the call lands.
