This guide demonstrates how to use Arize and Coval together to evaluate voice AI applications, combining Arize's deep system-level observability with Coval's conversation-level simulation and evaluation capabilities.

Overview

Arize provides comprehensive observability for voice AI applications, capturing detailed traces of internal system calls, audio processing events, and performance metrics. It allows you to deep dive into the technical implementation and troubleshoot issues at the system level.

Coval pulls traces from Arize and provides conversation-level simulation and evaluation capabilities. With just your API key, Coval can access your Arize traces and enable higher-level testing, simulation, and evaluation of entire voice conversations.

Architecture

• Voice AI Application sends detailed traces to Arize

• Arize captures system calls, API events, and technical metrics

• Coval pulls traces from Arize for conversation-level analysis and simulation
