Transcript-only rubrics miss the part customers actually react to. These six dimensions cover both.
- Pace
- Words per minute against the agent's own baseline, not a fixed number. Drift above baseline is the earliest reliable signal that a call is going badly.
- Warmth / affect
- Flat delivery on a compliant script still loses the sale. Prosody, not wording, carries most of this.
- Talk-to-listen ratio
- Long uninterrupted monologues correlate with disengagement. Track the longest single stretch, not just the average.
- Objection handling
- Was the objection acknowledged before it was answered? Recovery quality matters more than whether an objection appeared.
- Disclosure compliance
- For regulated queues, whether required disclosures landed before benefits were discussed. Binary, and non-negotiable.
- Recovery
- After a bad moment, how long until delivery returns to baseline. Fast recovery is a coachable, measurable skill.
