Every Amazon Lex Intent, Slot, and Lambda. One Platform.
AI agents that talk and call your Lex bot to exercise intent recognition, slot elicitation, Lambda fulfillment, and fallback over chat and voice.
Intent and Slot Testing
Users phrase the same request a dozen ways. TestMu AI utters every intent across variations over chat and voice, then scores each turn on 9 quality metrics.
Intent Recognition
Confirm Lex maps varied utterances to the right intent and never misroutes to a neighboring one.
Slot Elicitation & Validation
Check every required slot is prompted for, filled, and validated before the bot moves on.
9 Quality Metrics
Score bias, hallucination, completeness, context awareness, response quality, and more on every reply.
From First Utterance to Production
Before Launch and In Production
Simulate every intent and slot flow before you publish a bot version, then batch-analyze real production conversations with the same metrics.
Full Quality Coverage for Chat and Voice
Score intent recognition, slot filling, and speech-to-text accuracy alongside bias and hallucination, on both text and voice.
Containment, CSAT, and Handoff Trends
Track the metrics the business cares about, from containment rate and CSAT to sentiment and human-handoff trends.
Confidence-Weighted Verdicts
Every score is weighted by evaluation volume and carries a High, Medium, or Low confidence level, so you know when your Lex bot is ready to ship.
