introduction

What this voice AI agent does

The Live Call Translator template creates an AI interpreter that joins phone calls and translates between two languages in real time. It speaks only when translation is needed, preserving meaning, tone, and first-person perspective.


Designed for businesses serving multilingual customers, from service companies to healthcare providers to legal firms, this template eliminates the need for expensive interpreter services.


The template comes pre-configured with multilingual voice, three-way calling via the invite tool, and configurable language pairs.
