Changing the Agent Language
Published:
Overview
This guide explains how to change the language used by an AI Voice Agent. The platform supports multiple languages and, when using speech-to-speech models, can switch between languages dynamically during a call.
Steps to Change the Agent Language
- Navigate to Call Flows and locate the agent you want to edit.
- Ensure you are in the Advanced View.
- Locate the Language selector and choose the required language.
- Ensure the voice assigned to the agent matches the selected language — using an English-accent voice for a non-English language will produce unnatural results.
- Where possible, write the agent’s prompt in the same language as the selected language setting for the most natural output.
- Click Save to Draft or Publish to Production.
