OpenAI Realtime API: Building AI Customer Conversations That Convert
A practitioner's guide to deploying voice AI for B2B customer conversations — from architecture to compliance to performance measurement
- Why sub-300ms latency is not a technical benchmark but a user experience threshold that determines whether voice AI feels like a conversation or a phone tree
- The use case qualification framework for deciding where voice AI delivers ROI and where it destroys customer experience
- A practical architecture overview covering telephony integration, CRM connection, and session management
- Conversation design principles specific to AI — why human call scripts fail for AI deployment and what to build instead
- The performance measurement framework for voice AI that goes beyond call volume to revenue contribution
What's inside
A practical playbook built for B2B marketing and sales technology leaders evaluating voice AI for customer-facing applications — qualification calls, appointment setting, customer onboarding, or support escalation.

Use Case Qualification: Where Voice AI Works vs. Where It Shouldn't
A decision framework for identifying which customer conversation types are appropriate for voice AI deployment — and which should stay with human agents.
