Building reliable AI voice and chat agents is harder than it looks. Most teams still rely on manual QA: listening to calls, replaying transcripts, and guessing where things went wrong. This process is slow, inconsistent, and impossible to scale.
What you need is a real-time platform that evaluates conversation quality continuously — so issues are detected before customers complain.
Below, we break down the best platforms for evaluating AI conversation quality in real-time, including how Cekura helps companies ship reliable agents faster.
Why Real-Time AI Conversation Evaluation Matters
-
Manual QA doesn’t scale: Reviewing call recordings one by one is slow.
-
Edge cases slip through: Agents fail with accents, background noise, or unusual requests.
-
Customer trust is fragile: A single failed interaction can ruin user confidence.
-
Compliance risk is real: In regulated industries, missing errors can be costly.
That’s why companies are adopting automated testing and monitoring platforms designed for voice and chat AI agents.
Top 5 Platforms for Real-Time AI Conversation Quality
Here’s the list of the best 5 AI conversation QA software.
1. Cekura - End‑to‑end testing and observability for voice and chat
What it does: Generates thousands of test scenarios from your agent description, simulates diverse user personas, verifies instruction‑following and tool calls, and monitors live traffic with alerts and analytics. Includes production replay to re‑test fixes against real conversations.   
Best for: Teams that want one platform to evaluate and improve AI conversation quality in real time across voice and chat, with enterprise‑ready controls. 
Key highlights:
-
Scenario Generation: Auto-generate realistic test cases from agent descriptions.
-
Custom Personas: Test against varied accents, background noise, and speech patterns.
-
Hierarchical Metrics: Measure conversation quality across CSAT, latency, interruptions, and instruction following.
-
Production Observability: Monitor real calls with proactive alerts and analytics.
-
Prompt Improvement Suggestions: Automatically recommend better prompts when failures occur.
Cekura works across the entire agent lifecycle: from development to post-launch monitoring—ensuring reliability at scale.
2. Observe.AI
Focuses on agent performance analytics and QA automation for contact centers. Strong in sentiment analysis and compliance, but less specialized in pre-launch simulation.
3. CallMiner
A speech analytics platform that emphasizes post-call insights for customer experience and compliance. Great for historical analysis, but limited in real-time proactive monitoring.
4. Spearline
Specializes in call quality assurance for telco and contact center infrastructure. Strong on audio clarity and connection monitoring, but not built for AI agent testing.
5. Balto
Real-time guidance for human agents. Balto listens to conversations and suggests next best actions live. Strong for sales and support training, but not a platform for testing AI-driven conversations.
