Pre-production simulations
Run voice evals before launch using a library of scenarios or custom scenarios to check how an agent behaves across different conversations and personas.

Voice testing and observability for AI agents
Cekura is a voice testing and observability platform for teams building conversational AI and voice agents. It combines pre-production simulations with production monitoring so teams can validate prompts, test workflow behavior, and watch live calls for issues that affect quality.
The source shows the product focused on instruction-following, tool calls, conversational flow, and voice-specific signals. In practice, that means teams can replay difficult conversations, test across different personas, inspect live calls, and use the resulting data to catch regressions before they affect users.
Core capabilities
Production observability
Monitor live calls as they happen and track voice-specific signals such as gibberish detection, interruption tracking, latency, sentiment, and pitch.
Judge optimization
Tune evaluation prompts against real call recordings in a labs workflow by editing, replaying, and scoring calls until the judge matches ground truth.
Real-time alerting
Set thresholds and receive instant notifications for errors, failures, and performance drops through Slack, email, or webhooks.
Custom metrics and reporting
Build custom plots and filter production metrics by agent or date to review trends such as duration, sentiment, drop-off, and success rates.
Platform integrations and APIs
Integrate with supported voice platforms and access APIs for production call simulation, logging, and tool-call workflows.
Common use cases
Regression testing before release
Test how prompt changes affect core flows such as cancellations, reschedules, follow-ups, refunds, or other multi-step workflows before shipping them.
Persona and interruption testing
Stress-test call handling across different personalities, including interruptive or impatient users, to confirm the agent can recover gracefully.
Conversation replay and debugging
Replay known problematic conversations to reproduce failures and verify that a fix addresses the original issue without introducing new ones.
Production call monitoring
Monitor live production calls for latency, interruptions, sentiment, and other voice-specific signals so teams can spot quality issues as they happen.
Operational review and reporting
Use alerts, reports, and custom plots to track trends, review failures, and share operational data across the team.
Pros and Cons
Pros
- Covers both pre-production testing and production monitoring in one platform.
- Includes scenario libraries plus support for custom scenarios.
- Surfaces voice-specific quality signals rather than only generic transcript checks.
- Offers alerts, reports, and APIs for team workflows.
- Provides an enterprise path for access control, compliance, and custom integrations.
Cons
- The source does not provide full technical details for every integration, API workflow, or deployment option.
- Enterprise capabilities such as access control, self-hosting, compliance, and custom support appear to require a sales conversation.
