Voice Agent Builder
Editing a Workflow
Learn the fundamentals of building workflows with nodes, pathways, and conversation flow in the voice agent builder.
Overview
A workflow is a graph of connected nodes representing conversation stages, with pathways defining agent movement between stages.
Global Node
Contains instructions applicable across the entire call:
- Company context
- Overall agent goal
- Tone and personality
- Common objection handling
Node-Level Toggles
Add Global Prompt
- Recommended to inject Global Node instructions into most nodes
Allow Interruption
- Default "On": Bot stops and responds to user interruption
- "Off": Bot continues speaking, ignoring user input
Detect Voicemail
- Available only in Start Node
- Automatically disconnects if voicemail detected
Variable Extraction
Supported in Agent and End Call Nodes:
- Extract structured variables
- Define name, type, and description
- Examples: customer name, budget, interest
Webhook Node
- Executed at call end
- Sends payload to specific endpoint
- Use for:
- Storing call data
- Triggering automation
- Syncing with CRMs
Editing Workflows
- Selectively delete nodes/pathways
- Completely reset workflow
Pathways and Tool Calls
- Define agent node movement
- Use tool calls to transition between nodes
- "tool" is a reserved keyword for function calls and actions
Voice Agent Builder
Talkr's voice agent builder lets you design a conversation as a graph of nodes and pathways. Learn the graph model, the available node types, and where to start.
Pre-recorded Audio
Build hybrid voice agents that combine pre-recorded audio with dynamic text generation for lower latency, reduced TTS costs, and natural-sounding conversations.
