Native Speech-to-Speech Voice AI Support in Chat Widget

šŸ‘€ Whatā€™s New?
Chat Widget now supports HighLevelā€™s native
Speech-to-Speech (S2S) Voice AI agents
alongside existing Voice AI agents.
  1. S2S and existing Voice AI agents are available within the
    same Agent dropdown
    .
  2. The Chat Widget automatically identifies the selected agent type and launches the appropriate voice experience.
  3. Existing Voice AI agents continue to work as before, with
    no changes required to the widget UI or embed code
    .
  4. If an existing agent is switched to a supported S2S model, widgets already using that agent update automatically.
  5. The existing Chat Widget calling experience remains unchanged, including:
  • Two-way audio
  • Mute / unmute
  • Call status
  • End-call controls
  1. The S2S SDK is loaded only when a visitor initiates a call with an S2S agent, keeping regular widget loads and existing Voice AI calls unaffected.
šŸ‘· How It Works:
  1. Enable
    Speech-to-Speech Voice AI
    from Labs.

  1. Save the widget.
  2. The widget automatically launches the correct voice experience when a visitor starts a call.
When an existing agent is switched to an S2S model, widgets already linked to that agent update automatically,
no re-save, re-embed, or new agent ID is required
.
If a cloned agent is used instead, select the new cloned agent within the Chat Widget builder.
ā­ Why It Matters:
  • Agencies can now use HighLevelā€™s native
    S2S Voice AI agents across both phone and website Chat Widget conversations
    .
  • Existing widgets can adopt S2S capabilities without requiring website code changes or widget reconstruction.
  • A unified agent picker simplifies configuration by removing the need for separate S2S and Voice AI setup flows.
  • Automatic syncing makes it easier to upgrade existing agents to S2S models without manually updating every widget.
  • On-demand SDK loading ensures S2S functionality is introduced without impacting standard Chat Widget performance.
šŸ“ Notes:
  • Availability: Live in production for agencies with
    Speech-to-Speech Voice AI enabled through Labs
    .
  • Existing Voice AI agents and widgets remain fully compatible.
  • Existing embed snippets do not need to be updated.
