Find the failures your voice agent only reveals on a live call.

Voice exposes failures that never surface in chat — interruptions, latency, accents, topic shifts, and ignored escalation requests. We put real humans on the line to find them under the conditions your agent will actually face.

Common failure modes

Where voice agents quietly fall apart.

Barge-in breakage

The caller interrupts and the agent talks over them, loses the turn, or restarts its script.

Accent & speech gaps

Mishears non-standard accents, fast speech, or words that trail off mid-sentence.

Context collapse

Forgets what was said two turns ago when the caller jumps between topics.

Dead-air & latency

Long pauses that make callers repeat themselves or hang up.

Escalation failure

Won't hand off to a human even when explicitly and repeatedly asked.

Objection fumbles

Falls back to a generic script the moment a caller pushes back.

Why voice is different

Text testing cannot find what breaks on a call.

On voice, the failures live in timing, audio, and turn-taking — not just wording. They never appear in a chat transcript, and they are exactly what a real caller triggers without trying.

  • Turn-taking and barge-in: who speaks when, and what happens when both do
  • Latency and dead air under real network conditions
  • Speech recognition across accents, pace, and background noise
  • Memory across a long spoken call with no transcript on screen
  • Escalation the moment a caller demands a human
