Author here. We run AI voice agents across a European hotel network. This post covers 6 months of call data and one change (removing the IVR) that revealed something we didn't expect — our old phone system was silently filtering out callers before they ever reached the AI, making our metrics look better than they were.
Happy to go deep on the voice pipeline, language detection, or anything else.
