Does the other person need an app?

No. They just take the call; SimulSpeak runs on your side, in the browser or on a device we hand you ready to go.

How many languages does it support?

24 languages, with sub-second latency so the conversation stays natural.

Does it really use my own voice?

Yes. It speaks the translation in a clone of your voice, so it still sounds like you.

Does the other person hear my voice or a robot?

Yours. The translation is spoken in a clone of your own voice, which is the part that keeps a translated call feeling like a conversation rather than a relay through a machine.

Is there a noticeable delay?

Latency is under a second, which is inside the range where people keep talking normally. Above that, both sides start waiting for each other and the call turns into a series of statements instead of a conversation.

Do I need to install anything?

No. It runs in the browser, and there is a ready-to-go device for situations where a browser is not practical. Twenty-four languages are available without any per-language setup.
