Key differences

Real-time emotional feedback

What gets measured

EchoDepth measures how a rep's delivery is landing using the VAD model (Valence, Arousal, Dominance). Second Nature measures conversational structure: objection handling scripts, talk time, key phrase usage. Different dimensions of sales performance.

The complementary case
