Personalizing AI Agent Voice for Natural Conversations

Selecting the right language and voice helps your AI agent sound more natural and relevant to the audience it is speaking with. In Awaz.ai, you can choose one or multiple languages for your agent, allowing it to support multilingual conversations based on your business needs.

You can also select from the available default voices, preview each voice before applying it, or add a new voice directly from the public ElevenLabs voice library.

Open Language Settings

To customize your AI agent’s language and voice:

Go to Agent Settings.
Select the AI agent you want to configure.
Locate the Language field.
Locate the Select Voice field.

From here, you can update the languages your agent can use and select the voice it will speak with during calls.

Select One or Multiple Languages

Awaz.ai now allows you to select multiple languages directly from the language dropdown.

Instead of selecting a separate “Multilingual” option, you can now choose the specific languages you want your agent to support. Once selected, each language will appear inside the language field.

You can select as many supported languages as needed, depending on the markets, customers, or regions your AI agent will be handling.

Example:
If your business serves customers in the United States, Brazil, and Japan, you can select:

English, United States
Portuguese, Brazil
Japanese, Japan

This allows your AI agent to support conversations across those selected languages.
