After creating an assistant, use the configuration page to set up its prompt, voice, call behaviour, and advanced options. Navigate to Assistants, then click on any existing assistant card to open its configuration page.

​
Configuration Sections

The left panel organises all settings into three groups:
  • Assistant Settings: Prompt · Voice · Custom Variables · Knowledge Base
  • Call Settings: Call · Chat
  • Advanced Settings: Embed · Keyword Boosting · Custom Analysis

​
1. Prompt

Assistant Settings → Prompt The Prompt section defines what the assistant says and how it behaves.

​
First Message

The exact opening line the assistant speaks when the call connects.
  • Use @{{variable_name}} to insert dynamic values (e.g. @{{callee_name}})
  • Type @ to open the variable picker
  • The Interruptible toggle: when ON, the callee can speak before the assistant finishes the opening line
Example: 
Hello, नमस्कार! क्या मैं @{{callee_name}} जी से बात कर रही हूं, या उनके parents से?

​
Objective

A paragraph that tells the assistant who it is, what it’s doing, and what it’s trying to achieve. Example: 
You are Ananya, a warm and knowledgeable academic counsellor calling on behalf of Aakash Digital.
Your goal is to identify preparation gaps and secure an enrollment confirmation or demo booking.

​
Response Guidelines

Rules the assistant follows throughout the conversation:
  • Tone and persona rules (e.g. “Keep responses 20–45 words per turn”)
  • Language switching logic (e.g. “Use formal आप when speaking Hindi”)
  • Escalation or handoff conditions

​
2. Voice

Assistant Settings → Voice
FieldDescription
Primary LanguageThe main language for the conversation (e.g. Hindi, English (IN))
Secondary LanguageOptional fallback language
Voice CharacterThe voice persona (Tanya, Naina, Raj, Rahul, Anya, etc.)
Toggle between Most Used and Neutral to filter available voices.

​
3. Custom Variables

Assistant Settings → Custom Variables Custom Variables are dynamic placeholders that get filled at call time — typically from your campaign’s calling list CSV. Examples:
  • {{callee_name}} → “Vikram”
  • {{mrp}} → “50000”
  • {{loan_amount}} → “₹1,20,000”
Use these in your First Message and Objective to personalise every call automatically.
