Fallback Voices in Agents

Ensure smooth and reliable voice calls with customizable backup voice options.

How It Works

Fallback Voices allow you to pre-select one or more backup voices when configuring an agent. If the primary voice fails during a call, the system automatically switches to the first available fallback voice. If no fallback voice is set, the system continues with the existing automatic selection behavior.

The UI clearly shows that fallback voices are optional, so you can configure them only when you want added reliability.

• Fallback Voices selection was added to the agent editor.
• Automatic failover switches to your chosen backup voice if the primary voice fails.
• Optional setup means nothing changes if you don’t configure fallback voices.

Why It Matters

• Improved reliability: Calls continue without interruption even if a primary voice fails.
• Consistent experience: Reduces the risk of jarring or unexpected agent voice changes.
• Greater control: Choose how your agents sound in different scenarios.
• Standards aligned: Matches Retell’s API capabilities for voice configuration.

This update is now live and available in the agent editor.
