Why SimulSpeak

Built for real conversations.

Real-time

Streaming speech-to-translation-to-speech, paced for sub-second latency. It feels like a normal conversation.

Your own voice

Cloned-voice output, so the other side hears you, not a synthetic stand-in.

24 languages

Hungarian, Chinese, Spanish, English, German and more, in any direction.

Browser & device

Share a link for an instant call, or run the full suite on a dedicated handset.

Private by design

Calls run on our own infrastructure. Your audio is never sold or mined.

Usage & history

Track minutes, review transcripts, and manage your plan from one place.

How it works

Live in three steps.

01
Pick your languages

Choose what you speak and what they speak. 24 options, in any direction.

02
Share a link or dial

Send a room link for an instant browser call, or type any phone number and we call them.

03
Just talk

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

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.

Questions

Good to know.

Do the people I call need the app?+

No. Share a browser link they open in one tap, or we dial their normal phone. There is nothing for them to install.

Which languages are supported?+

24 today, both directions, including Hungarian, Chinese, Spanish, English, German, Arabic and Korean.

How fast is it?+

Sub-second added latency. It streams as you speak, so the conversation flows like a normal call.

Is it really my voice?+

Yes. The translation is spoken in a cloned version of your voice, so you sound like you in every language.

Can I cancel anytime?+

Yes. Plans are monthly and you can cancel from the billing page whenever you like.

What is the Concierge handset?+

A phone we mail you, fully configured, that also translates live inside WhatsApp and WeChat.
