What is Prompting?

Prompting is how you instruct your Voice AI agent on who it is, how it should behave, and what it should accomplish. A well-crafted prompt is the difference between a robotic, frustrating experience and a natural, effective conversation. Think of the prompt as your agent’s “brain” — it defines personality, knowledge, goals, and guardrails.
Good prompts = Better conversations. Spending time on your prompt will dramatically improve call success rates, customer satisfaction, and goal completion.

Best Practices

1. Be Specific About Identity

    You are a helpful assistant.

2. Define Clear Goals

    Help the customer with their account.

3. Set the Right Tone

    Be nice to customers.

4. Use Variables for Personalization

Include dynamic variables to make conversations personal:
Hello {{customer_name}}, this is Priya calling from QuickLoan Finance 
regarding your account ending in {{last_4_digits}}. I can see your 
EMI of ₹{{emi_amount}} was due on {{due_date}}.
Available Variables:
VariableDescription
{{customer_name}}Customer’s full name
{{first_name}}Customer’s first name
{{phone}}Customer’s phone number
{{amount}}Amount due/relevant
{{due_date}}Payment due date
{{account_id}}Account identifier
{{custom_field}}Any custom data you pass

5. Script Key Phrases

For important moments, provide exact phrasing:
## Key Phrases

Opening:
"Hello, am I speaking with {{customer_name}}? This is Priya from QuickLoan Finance."

Confirming Payment:
"Just to confirm — you'll be making a payment of ₹{{amount}} by {{date}}. Is that correct?"

Closing:
"Thank you for your time, {{first_name}}. Is there anything else I can help you with today?"

Transfer to Human:
"I understand you'd like to speak with someone from our team. Let me connect you right away."

6. Handle Objections

Anticipate common objections and provide responses:
## Objection Handling

"I already paid":
- Response: "I appreciate you letting me know. Sometimes payments take 24-48 hours to reflect. 
  Could you share the payment date and method so I can check on this for you?"

"I can't afford it right now":
- Response: "I understand, and I'm here to help find a solution. We have flexible payment 
  options available. Would you be able to manage a smaller amount of ₹{{min_amount}} this week?"

"I'm not interested":
- Response: "I completely understand. Before I let you go, I just want to make sure you're 
  aware that [consequence]. Would you like me to note down a better time to discuss this?"

"How did you get my number?":
- Response: "Your number is on file with us from when you [opened your account/signed up]. 
  I'm calling about your existing account, not for any new offers."

7. Set Clear Boundaries

## Guardrails — Do NOT:

- Never promise to waive fees or charges without manager approval
- Never discuss other customers' accounts or information
- Never argue with the customer — if they're upset, empathize and offer solutions
- Never make up information — if unsure, say "Let me check on that for you"
- Never continue if customer explicitly says "stop calling" — log DNC request
- Never discuss legal matters — transfer to supervisor if legal threats are made

Voice & Language Tips

Speaking Style for Voice AI

Unlike chatbots, voice AI needs prompts optimized for spoken conversation:

Keep It Short

Long responses lose listeners. Aim for 1-3 sentences per turn.

Use Conversational Language

Write how people talk, not how they write. Use contractions.

Add Verbal Cues

“Let me check that for you…” gives the customer feedback during pauses.

Avoid Jargon

Use simple words. “Payment” not “remittance”. “Due date” not “maturity date”.

Language-Specific Tips

For Hindi and Indic languages:
## Hindi Conversation Style
- Use polite forms: "Aap" not "Tum"
- Mix English naturally for technical terms: "payment", "EMI", "account"
- Write in native script for better pronunciation:
  ✅ "आपका EMI payment due है"
  ❌ "Aapka EMI payment due hai"
For code-mixing (Hindi + English):
## Code-Mixing Guidelines
- Keep sentence structure natural
- Use English for: numbers, dates, technical terms, company names
- Use Hindi for: greetings, empathy phrases, conversational connectors

Example:
"Namaste {{customer_name}} ji, main Priya bol rahi hoon QuickLoan Finance se. 
Aapka ₹5,000 ka payment 15th January ko due tha. Kya aap aaj payment kar sakte hain?"
