Hallucination risk in voice AI: reducing wrong answers on the phone
Voice AI hallucination prevention: voice-specific risks, four rules — approved sources, answer boundary, honesty, risk levels — and a test set.
This section covers making an AI voice agent dependable: a pilot with a narrow start and clear decision criteria, the metrics that measure its work, the risk of wrong answers and an incident process for them, a knowledge base written to be spoken, testing a call flow before changing it, and call recording, consent and retention.
Trust is built on evidence, not promises. How data is protected is on the security page, and where answers come from is on knowledge base.
