Voice Support Agent — Canonical Workflow
Voice Support Agent: provisional AI workflow implementation reference with candidate models, providers, tools, and architecture.
Overview
A voice support agent handles inbound tier-1 calls with speech-to-text transcription, real-time intent detection, and a RAG layer that retrieves policy and product information to ground responses. A sentiment model monitors the caller's emotional tone and triggers an escalation to a human agent when frustration or urgency signals exceed a threshold. All calls produce a full timestamped transcript, an intent classification and a structured action-item log, giving QA teams auditable records and enabling automated CSAT prediction.
