How to run multilingual business calls without an interpreter

June 9, 2026·5 min read

A practical guide to holding sales, supplier, and support calls across languages — by phone, in the browser, or inside WhatsApp and WeChat.

Expanding across borders used to mean either hiring interpreters or hoping everyone could muddle through in a shared second language. Real-time translation removes that constraint: you can run a multilingual call today, with no interpreter and no app for the other side to install.

Pick the right channel

Different conversations call for different connections. SimulSpeak supports three, so you can match the tool to the situation:

  • Browser room: share a one-tap link; the other person joins in their browser using WebRTC — nothing to install.
  • Phone call: type any number and we dial it over the phone network (SIP/PSTN), translating both directions.
  • Chat apps: on the Concierge device, translate inside WhatsApp and WeChat — voice notes, calls, and messages.

Set your languages and go

Choose what you speak and what the other person hears. With 24 languages in both directions and the ability to switch the language pair mid-call, you are covered even when a conversation drifts between languages — common in multilingual teams.

Tips for a clean call

  • Use headphones to avoid echo and keep the translation crisp.
  • Speak in normal, complete phrases — natural pacing recognises better than clipped words.
  • For phone calls, let the first exchange settle so both sides hear the rhythm.

Why it works for business

Because it is instant and available 24/7, real-time translation lets you close deals in new markets, manage a global workforce, and support customers in their own language — without the cost and scheduling of a human interpreter. The conversations that used to be blocked by language simply happen.
