Why emotional intelligence beats conversation intelligence

Chorus tells you that your rep spoke for 43% of the call and mentioned pricing twice. EchoDepth tells you that their confidence index dropped at minute 7, their composure recovered by minute 12, and the buyer's engagement signal peaked when they pivoted to ROI. One is data. The other is insight.
