What Is Communication Intelligence?
Communication Intelligence is technology that analyses delivery patterns from facial expressions, vocal patterns and language — providing the measurement layer for high-stakes conversation coaching and improvement.
Communication Intelligence is technology that analyses delivery patterns from observable signals — facial Action Units, vocal patterns, and language. It provides the measurement layer that converts communication delivery into structured, actionable coaching.
How Communication Intelligence Works
Communication Intelligence systems process visual, audio or text input to analyse delivery patterns. The most scientifically validated approach uses the Facial Action Coding System (FACS) — a comprehensive framework for measuring facial muscle movements developed by Paul Ekman and Wallace Friesen.
EchoDepth analyses 44 facial Action Units under the FACS standard. This level of granularity — significantly more detailed than broad sentiment or expression classification — allows EchoDepth to identify the subtle delivery patterns that affect communication outcomes.
Communication Intelligence vs Sentiment Analysis
Sentiment Analysis
- Positive / Negative / Neutral classification
- Text or audio-based primarily
- Aggregated signal — not individual
- Retrospective — analyses past content
- No cultural calibration
EchoDepth Communication Intelligence
- 44 facial Action Units — granular pattern mapping
- Multimodal — facial, vocal, linguistic
- Individual-level signal — person-specific
- Real-time and retrospective
- 14 cultural cohorts across 6 countries
The FACS Standard
The Facial Action Coding System (FACS) is the gold standard for facial communication measurement. It maps the face into Action Units — specific muscle movements that combine to produce observable expressions. EchoDepth implements 44 Action Units, enabling analysis of complex delivery patterns that simpler systems cannot distinguish.
Communication Intelligence Applications — Enterprise Contexts
Communication Intelligence is not a single deployment — it is a measurement capability that applies wherever communication quality determines outcome. The following are the highest-value enterprise applications.
Pre-live analysis of earnings calls and shareholder presentations. Identifies credibility gaps and stress signals before markets react.
Real-time buyer emotional signal during demos. Generates Buyer Engagement Score and Objection Signal Map per rep.
Resistance signal detection in pre-launch messaging. Identifies emotional trigger points before programme rollout.
Interviewer Consistency Score across panels. Makes the emotional response to candidates visible and accountable.
Operator-augmented threat signal detection. Quantified behavioural risk score independent of operator experience.
Frame-by-frame emotional response curve on creative content. Real engagement vs declared preference.

Frequently Asked Questions
What is emotional AI?
Communication intelligence technology analyses patterns in language, tone and delivery. EchoDepth by Cavefish uses the FACS standard to measure delivery quality and communication risk.
What is the FACS standard in emotional AI?
FACS stands for the Facial Action Coding System — a comprehensive framework for measuring facial muscle movements. EchoDepth analyses 44 facial Action Units under the FACS standard.
What is the VAD model in emotional AI?
VAD stands for Valence-Arousal-Dominance — a three-dimensional model for emotional state representation. EchoDepth uses the VAD model to provide significantly more granular emotional state mapping than binary positive/negative classification.
Is communication analysis the same as decision intelligence?
Communication analysis is the measurement layer — analysing how messages land in delivery. Decision intelligence is the application framework that converts those signals into actionable insight. EchoDepth delivers both.
