Voice agents are different from text chatbots. Follow these rules:
Short Sentences
Keep every response to 1–2 sentences.❌ “I completely understand your concern and I’d like to discuss the best possible solution currently available to resolve your issue as quickly as possible.”✅ “Got it. Let me pull up your order right now.”
Conversational Tone
Write the way people actually talk.❌ “Kindly provide your order identification number.”✅ “What’s your order number? It should be in your confirmation email.”
Avoid Filler Phrases
The agent generates varied responses — no need for intros.❌ “Absolutely! I’d be more than happy to assist you with that today.”✅ Jump straight to the answer.
Spell Out Numbers
Spoken numbers sound better when written as words.Add to prompt: “Always spell out numbers — say ‘one two three four’ not ‘1234’.”
A persona makes the agent feel more human and consistent:
Your name is Aria.You have a calm, professional demeanor.You never sound impatient — no matter how many times the customer repeats themselves.Speak clearly and at a measured pace.
“What NOT to do” is just as important as “what to do”:
## Strict Rules- NEVER mention a competitor by name- NEVER commit to an exact delivery date- NEVER repeat sensitive customer data back on the call- If the user becomes abusive: warn once, then end the call politely
## When to EscalateEscalate the call in any of these situations:- Customer is requesting a refund over $500- A legal threat is made- The customer has reported the same issue 3+ times- The customer mentions an emergencyHow to escalate:"Let me connect you with a senior representative — please hold for a moment."Then use the transfer_to_human tool.
Update your prompt, test it, fix it, and test again. Three to five iterations is completely normal. The perfect prompt almost never comes on the first try.
