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.

Outbound voice AI QA tests voicemail, IVR menus, and transfer paths before a dialer scales. Cekura runs simulated outbound calls and scores every transcript.

Piper TTS is a free, open-source neural TTS engine that runs on-device, now under GPL-3.0. See its metrics, licensing, and how Cekura tests TTS output quality.

QA as a service explained: what vendors deliver, pricing models, build vs. buy math, and how AI changes the tradeoffs. Read the vendor checklist first.

Platform to run regression tests on Retell agents after prompt changes: Cekura replays a fixed scenario set as real calls across two Retell agent versions on identical evaluator sets, where Retell's only graded testing runs as text.

Regression testing for voice AI agents means re-running a frozen scenario suite after every prompt change and comparing scored results. How the loop works, what to cover, and how Cekura runs it from CI.
