Message Testing &
Insight
Know how a communication will land before it goes live. EchoDepth returns scored, timestamped signal data from real content — not stated recall, not claimed response.
Traditional research tells you what people say they felt. Not what actually happened.
Focus groups, claimed recall and post-exposure surveys all share the same flaw: they measure what participants choose to report, filtered through social desirability, memory and the moderator's framing.
EchoDepth measures the communication signals that occur in the moment of exposure — facial delivery response, vocal pattern and linguistic signal — returning a timestamped record of what the content actually produced, not what the audience later decided to say about it.
What people say they felt in a focus group diverges significantly from their signal response at the moment of exposure. EchoDepth closes that gap.
Results are returned at the second level — you know exactly which frame, line or transition caused a credibility drop or trust peak.
Scored, documented outputs that can be presented to boards, clients or media buyers as objective evidence rather than interpreted opinion.
Use cases
Where organisations use EchoDepth for message testing and insight.
Campaign creative testing
Test TV, digital and social creative against real audience signal before media spend commits. Identify which executions carry genuine emotional connection versus surface attention.
Script and voiceover testing
Compare script variants and voice talent against audience response data. Know which combination lands the intended message — scored, timestamped, evidence-based.
Leadership and CEO address
Before a major announcement goes to the whole organisation, test how it lands with a representative sample. Identify credibility drops, trust signals and the moments that need revision.
Investor and analyst communications
Test how guidance language, delivery pace and confidence signals in earnings narratives register before results day. Return confidence to the board.
Product and brand messaging
Test positioning statements, product launch scripts and brand narratives against signal data. Know what resonates versus what leaves audiences neutral before production spend.
Change programme communications
Before a transformation message reaches thousands of employees, test how it lands with a pilot group. Surface resistance signals, trust gaps and the specific language that is creating friction.

Common questions
What is the difference between EchoDepth and focus groups?
Focus groups capture what people say they felt. EchoDepth measures what actually happened in communication signals at the moment of exposure — vocal, facial and linguistic response. The two complement each other: EchoDepth identifies which moments to probe in qual research.
What types of content can EchoDepth test?
Campaign video and audio, scripts and voiceovers, recorded presentations, CEO addresses, product launch content and investor communications. Any content where the emotional response of the audience matters to the outcome.
How quickly do results come back?
Standard turnaround is 5 working days for a full scored report. Expedited analysis is available for time-critical campaign launches. Contact hello@cavefish.co.uk for urgent requirements.
Can consultancies use EchoDepth in client projects?
Yes. Research and communications consultancies use EchoDepth as an evidence layer within client engagements. Partners access analysis outputs, white-label reporting and API integration. See the Partners page for commercial terms.
