What an AI voice collection call actually sounds like
AI voice agents for invoice collection are not the robocalls from the 2010s. Modern text-to-speech (OpenAI, Deepgram, ElevenLabs) produces natural-sounding voices that are difficult to distinguish from a human caller. Pitch, pacing, and intonation are tuned for professional business communication rather than the flat, mechanical sound of legacy TTS.
The script is dynamic, not scripted. Remi (Surety's voice agent) generates a unique call script for each invoice based on the customer's name, invoice amount, days overdue, and prior payment history. First-time late payers get a warmer, lighter script. Chronic slow-payers get a more direct one.
How AI voice collection calls handle responses
The most common response to an AI collection call is one of three things: the customer pays immediately after receiving the follow-up SMS with a payment link, the customer says they'll pay by a specific date (a soft commitment the system records and follows up on), or the call goes to voicemail.
For voicemail, Remi leaves a professional, concise message with a callback number and a follow-up SMS with the payment link. The SMS follow-up after a voicemail increases payment rate significantly — the customer has a reminder in their text history even if they delete the voicemail.
For DTMF (keypress) responses, the system handles 'press 1 to pay, press 2 to speak to someone, press 3 for a callback' dynamically. You define the logic; Remi handles the interaction.
What customers actually think about AI collection calls
The concern most business owners have is that AI calls will annoy customers or damage relationships. The data tells a different story. Customers who receive a professional, non-threatening reminder call — whether from a human or an AI — report similar satisfaction scores. What matters is tone and timing, not the technology behind it.
The businesses that have the best outcomes with AI collection calls are the ones who configure Remi with a tone that matches their brand: professional, helpful, and solution-oriented rather than threatening. The goal of the call is to make it easy for the customer to pay, not to pressure them.
Compliance and disclosure in AI voice collection
FDCPA (Fair Debt Collection Practices Act) requirements that apply to collection agencies do not apply to businesses collecting their own debts. As a business collecting your own invoices, you have more latitude than a third-party agency. However, some states have specific requirements around disclosing AI in phone calls.
Surety handles compliance automatically: calls are placed only during business hours, disclose the call is for billing purposes, respect opt-out requests, and never use threatening or misleading language. If your state requires disclosure of AI usage, that's configurable in your account settings.
