We Show Which Parts of Your
Keynote Actually Worked.

Applause at the end tells you it went well. EchoDepth Events tells you the exact moment it went well — and the 4-minute stretch in the middle where half the room drifted. That's the data that changes how you speak, plan, and invest.

Audience coverage — every seat, every minute

Whether You're On Stage, In the Room, or Booking the Room

Speakers & Presenters

You put weeks into that talk. Find out which five minutes had the room leaning in — and which two minutes you can cut next time. Real feedback, not polite applause.

  • ✓ See your engagement curve minute by minute
  • ✓ Identify your best moments to repeat them
  • ✓ Find the drift points before you present again

Event Organisers & Producers

You're responsible for the programme. Now you can prove which sessions delivered — and brief future speakers with real audience data, not vibes.

  • ✓ Compare engagement across all sessions
  • ✓ Identify which formats hold attention longest
  • ✓ Show sponsors audience engagement, not just headcount

Marketing & Content Teams

That keynote was also a content moment. Find out which section generated the reaction, which slide made people sit up, and what message to amplify in your follow-up.

  • ✓ Map content performance to audience reaction
  • ✓ Identify the moments worth clipping and sharing
  • ✓ Build the post-event content strategy on evidence

An Engagement Timeline.
Moment by Moment.

After every keynote, you get a timeline that shows audience engagement from the first word to the last. Not a score out of ten — a curve that shows exactly what happened, when.

Peak Engagement Moments

The three to five moments your audience was most locked in. These are the lines, the stories, the demos that worked.

Drop-Off Points

Where attention faded. Often a passage that felt fine to the speaker but lost the room. Now you can see it.

Audience Size Curve

How many people were in the room, and when they arrived or left. Did you lose them before the close?

Zone Performance

For larger venues — which section of the room engaged most? Are people at the back checked out by minute ten?

Top Moments Summary

A plain-English summary of the content moments that landed — ready to share with your speaker or use in debrief.

Two Ways to Measure Keynote Engagement

Start with Standard — no consent, no friction, no legal overhead. Upgrade to Deep when you need the full emotional picture and have the delegate opt-in in place.

No Consent Required

Standard

Behavioural signals only. Works anywhere, for any audience, right out of the box.

Footfall — who's in the room and when
Dwell time — how long they stay
Movement vs stillness — attention proxy
Crowd density and clustering
Zone heatmaps
Audio response — applause, noise spikes (optional)
Engagement score over time + peak / drop-off report
GDPR position: No facial recognition, no biometrics, no individual tracking. Anonymous aggregated signals only. No consent required.

Delegate Opt-In Required

Deep

Everything in Standard, plus the full emotional picture. Requires delegate consent — ideal for registered events and conferences.

Delight and surprise moments identified and timestamped
Connect speaker content to audience emotional response
Staff and speaker performance benchmarking
GDPR position: Requires delegate opt-in, typically via event registration. We provide consent language and a DPIA template. No biometric data stored; only aggregated signal scores retained.

Any Session Where the Audience Response Matters

Annual Conference Keynotes

Your opening and closing keynotes set the tone. Know whether they delivered. Brief next year's speaker with data from this year's audience.

Product Launch Presentations

Which feature announcement landed? When did the room light up? When did it go quiet? Find the moments worth amplifying in your post-launch content.

Tradeshow Presentations

Stage talks and demo theatre sessions that run all day. See which slot, which presenter, and which content format held attention the longest.

Training & Workshop Sessions

Did the learning land? Track attention across a full-day workshop and identify which segments to rebuild, re-pace, or cut entirely.

Awards Ceremonies

Which segment of the evening had the room at its most engaged? Useful for hosts, producers, and sponsors evaluating their visibility moments.

Internal Town Halls

Leadership communication that needs to land. Not just attendance — did they listen? Did the message connect? Now you can find out.

What People Ask Us

No. Standard tier measures behavioural signals only — movement, dwell, density, and crowd patterns. There's no facial recognition, no biometrics, and no individual tracking. Standard CCTV signage noting that analytical cameras are in use is sufficient in most GDPR contexts. We provide the signage template.

Deep tier uses emotion signals which require delegate opt-in. For registered conferences, this is typically handled through the event registration process — a single checkbox and a brief plain-English explanation is sufficient. We provide the consent language, DPIA template, and supporting documentation. Most events collect consent within the existing registration flow with no additional friction.

Yes. The engagement timeline is timestamped to the second. If you provide a timestamped script or slide deck sequence, we can annotate the timeline to show which content moments correspond to which engagement peaks and drop-offs. This is the most direct way to connect speaker content to audience reaction.

The live dashboard shows engagement in real time during your session — so your event team can see the curve as it happens. The full annotated post-event report, including top moments summary and recommendations, is delivered within 5 business days.

We recommend sessions of 20 minutes or longer for a meaningful engagement curve. Shorter talks produce useful snapshot data but fewer inflection points. For panel sessions, multi-speaker segments, and workshops over 30 minutes, the data is particularly rich.
