The best AI evaluation tools for production, judged on five buying criteria: live scoring, a pinnable judge, sample size, reproducibility, voice coverage.

A practical guide to Cartesia text to speech: what Sonic 3.6 actually ships, where the vendor latency claim stops, and how to test voice quality yourself.

The common failure points in AI phone agents, from endpointing and dead air to dropped tool arguments, with the delay budgets and tests that catch each one.

How to test voice AI agents from your IDE: the three loops it covers, scenario runs your coding assistant starts and reads, and debugging without leaving the editor.

How to evaluate a SOC2 compliant voice AI testing platform: what a SOC 2 Type II report actually covers, why the vendor's own posture matters once it holds your call recordings, and how PCI work differs. SOC 2 covers the platform, not your agent.

Tools to test voice AI agents built on Deepgram Voice Agent: what to cover across listen, think and speak, how to run and score scenario calls, and how to monitor the agent in production.

Voice AI testing for retail and ecommerce: what to test in catalogue lookups, order tool calls, returns policy and peak season concurrency, and how Cekura runs those tests as simulated calls against your live agent.

How to test voicemail detection on outbound voice AI agents: the scenarios that expose misclassification, the platform settings worth varying, and how to run the suite on every release.

Compare open-source and hosted agent eval frameworks for trajectory, tool-call, and task-completion testing, then set up your first CI-gated eval run.

Barge in is when a caller interrupts a voice agent mid-response. See how it's detected, measured, and tuned, then check Cekura's live benchmark scores.

An LLM eval framework grades model outputs against benchmarks and rubrics. See how top tools compare and use the framework comparison table to choose yours.

What an on-premise voice AI testing deployment actually requires: the media path and inference you run yourself, the licensing traffic that still leaves the network, and how to keep call audio inside your boundary.
