Voice Agent Testing Methodology: Separating ASR Failures from Downstream Logic
Admirable-Wallaby457 · reddit · 2026-08-25
The author proposes a testing methodology for production voice agents and IVR systems to improve failure root cause analysis.
Core Problem: When a voice interaction fails, is the cause the speech/ASR layer, or would the downstream intent/workflow have failed anyway?
Solution:
- Compare test results via a "reference-text path" versus a "speech/ASR path".
- Attribute failures based on the deltas between the two paths.
Value: Makes regression testing and defect triage more useful than looking at transcription accuracy alone. The author has built a working framework and is seeking practitioner feedback.
