Patter SDK Guide to Building a Restaurant Booking Phone Agent with Dynamic Variables, Guardrails, Latency Dashboards, and Eval Checks

MarkTechPost · 3 months ago · 11

A tutorial demonstrates how to build a voice-agent phone assistant for restaurant bookings using the Patter SDK, covering tool registration, output guardrails, speech simulation, latency tracking, and evaluation checks. The agent handles booking requests by parsing party size, date, and time slot from caller input, manages state across conversation turns, and applies safety guardrails to redact PII, filter profanity, and block off-topic requests. The tutorial shows how to integrate agent logic, tool use, safety checks, and call simulation into a single structured voice-agent pipeline without requiring live telephony credentials.
