Key differences

Feedback type

EchoDepth delivers objective, real-time feedback from 44 FACS facial Action Units and VAD emotional state analysis. No manager review cycle. Rehearsal.ai relies on asynchronous manager or peer review of recorded video — feedback is subjective and depends on reviewer quality and availability.

Scalability

EchoDepth scales without manager time — every rep gets consistent, objective coaching regardless of team size. Rehearsal.ai's model requires someone to review each recording, which creates a bottleneck that grows linearly with team size.

What gets measured

EchoDepth measures emotional state — Confidence, Warmth, Authority, Composure — using facial Action Unit analysis. Rehearsal.ai collects subjective rubric scores from human reviewers. The difference is objectivity: EchoDepth produces the same feedback regardless of who is doing the reviewing.

FAQs

How does EchoDepth differ from Rehearsal.ai?
Rehearsal.ai uses video roleplay with asynchronous manager or peer feedback. Feedback is subjective and depends on reviewer quality. EchoDepth provides objective, real-time feedback from measured FACS emotional data — no manager review required, no subjectivity in the coaching signal. EchoDepth scales linearly; Rehearsal creates a review bottleneck.
Does Rehearsal.ai measure emotional presence?
Rehearsal collects subjective rubric scores from human reviewers on recorded videos. It does not perform automated emotional expression analysis. EchoDepth analyses 44 facial Action Units in real time and maps to VAD emotional state — producing objective metrics independent of any reviewer.
Can I use EchoDepth and Rehearsal.ai together?
Potentially. Rehearsal provides the video capture and manager review workflow. EchoDepth adds the objective emotional performance layer. However, EchoDepth's real-time feedback during practice — not post-hoc review — is the primary coaching mechanism, which partly overlaps Rehearsal's core use case.
