Two voice modes now available in the AI Agent Handoff tool
7, Jul 2025
We are excited to announce a major enhancement to the AI Agent Handoff tool: support for two distinct voice modes. Now, you can choose whether all your AI assistants speak with a unified voice for seamless handoffs, or let each assistant retain its own voice to create the experience of a team collaborating on the call. This update gives you greater flexibility to craft the most natural and effective conversations for your users.
What’s new
This tool now gives you more control over the voice experience during multi-agent handoffs. Choose between:
Unified voice mode (existing): All AI agents share the same voice, making handoffs seamless and invisible to the user.
Distinct voice mode (new): Each agent keeps its unique voice settings, so handoffs feel like a collaborative team of specialists, just like a real conference call.
Key benefits
Personalized experiences: Give each AI agent its own voice and persona to reflect their unique expertise or function.
Seamless transitions: Maintain a single voice for uninterrupted conversations, or highlight handoffs with distinct voices for clarity.
More natural multi-agent interactions: Create the feel of a real team, helping users understand when different assistants are handling different parts of a conversation.
Flexible configuration: Instantly switch between voice modes in your settings with no code changes.
Why it matters
This update lets you tailor every user interaction, whether you want smooth, invisible handoffs or a collaborative, multi-expert environment where each assistant stands out.
