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.

What Chorus does well

Chorus (now part of ZoomInfo) captures and transcribes sales calls at scale. It extracts topics, tracks talk ratios, and flags competitor mentions. For teams that need searchable call libraries and content-based coaching, Chorus delivers.

The limitation is the same as all conversation intelligence tools: speech analysis cannot see what the rep's face and body communicated. Buyers read emotional signals faster than words. Chorus captures the transcript. EchoDepth captures the subtext.

The insight gap

Conversation intelligence tools answer: "What topics did we cover? How long did we talk?" These are useful post-call metrics. They do not explain why some reps convert and others do not when both cover the same topics.

EchoDepth answers the harder question: "How did the rep show up emotionally, and how did the buyer respond?" This is the layer that FACS research shows matters most for trust formation.
