Internal &
change communications
Updated October 2026
EchoDepth, from Cavefish, measures whether your people actually believe what leadership is telling them, across change programmes, training rollouts and restructuring communications. It shows where trust builds and breaks, before disengagement becomes attrition or a rollout fails.
How culture analysis works
Read emotion and trust in culture survey comments, change messages and training feedback, and see how an announcement lands before the attrition data does.
Read the transcript
The all staff email goes out. The town hall happens. The survey comes back with a score and 600 comments nobody has time to read. An engagement score tells you how people rated you.
It doesn't tell you what they heard. Echo depth for culture reads every comment for theme and feeling the same day with the comments that evidence each theme. Then it sets what leaders said beside what colleagues heard so you can see which promises landed and which were heard as threats. Before the next announcement, it reads the draft for lines likely to land badly and suggests a rewrite.
Messages, not people. It never monitors faces or voices at work, never names who said what, and never ranks individuals. Echo depth for culture, hear what your people heard. See what your customers feel.
Engagement surveys tell you what people are willing to admit. Not what they actually believe.
By the time a survey shows falling engagement, the resistance has usually been building for weeks - visible in the room, invisible in the dashboard. Compliance is easy to measure. Belief is not.
Cavefish measures the communication signal in leadership communications and training content at the moment of delivery - facial delivery response, vocal pattern and linguistic signal - returning a timestamped record of where trust builds and where it breaks, weeks before it shows up as attrition.
Training completion rates and survey scores measure compliance. Cavefish measures whether the message was actually believed - a different and earlier signal.
Results are returned at the second level - you know exactly which line, slide or moment in a town hall caused a credibility drop.
Scored, documented outputs that can be presented to leadership, HR or the board as objective evidence rather than interpreted opinion.
Use cases
Where organisations use Cavefish for internal and change communications.
Change programme launches
Test how a transformation announcement lands with a pilot group before it reaches the whole organisation. Surface resistance signals and trust gaps while there is still time to revise the message.
Compliance & training rollouts
Measure whether mandatory training - compliance, safety, systems - is actually landing, not just being completed. Identify where engagement drops and completion becomes box-ticking.
Town halls & all-hands
Score leadership credibility and audience engagement in recorded town halls. Know where the room was lost before it shows up in the next engagement survey.
Restructuring & redundancy communications
Rehearse high-stakes, sensitive announcements before delivery. Identify moments that read as evasive or lack empathy, and fix them before they reach staff.
M&A integration communications
Test how merger and integration messaging lands with two workforces that don't yet trust each other. Detect where cultural friction shows up in the signal.
Culture & values rollouts
Measure whether a new values or culture initiative lands as genuine or as corporate performance, and track congruence across the leadership team delivering it.

Common questions
How is this different from an employee engagement survey?
Surveys capture what people are willing to say, weeks after the fact, filtered by social desirability. Cavefish measures the signal in the room at the moment of delivery - detectable well before it would show up in survey or attrition data.
Can this be used before a redundancy or restructuring announcement?
Yes. Sensitive change and restructuring communications are one of the most common uses - rehearsing delivery before a legally and emotionally high-stakes announcement, where tone carries as much risk as content.
Does this replace change management consulting?
No. Cavefish gives change, HR and internal comms teams an evidence layer that sits alongside change management strategy, not in place of it.
How quickly can this be set up before a launch?
Standard turnaround is 5 working days for a scored report. For time-critical launches, contact hello@cavefish.ai to discuss expedited analysis.
How can HR and internal comms teams test whether a change message is believed?
Submit a recording or draft of the change message, training content or town hall to EchoDepth, from Cavefish, and the analysis shows whether people are likely to believe it. It covers change programmes, training rollouts and restructuring communications, and shows where trust builds and breaks. The analysis measures the facial, vocal and linguistic signals produced as the content is delivered, rather than relying on stated responses. Surveys usually lag behind this signal. By the time a survey shows falling engagement, resistance has often been building for weeks. Compliance is easy to measure, but belief is not. Teams receive a 0–100 Communication Risk Score, a per-second delivery timeline, timestamped coaching notes and a board-ready PDF report, typically within 5 working days. Cavefish works with HR, internal comms and transformation teams, and the findings are intended to inform revisions before disengagement becomes attrition or a rollout fails.
