How is the Credibility Signal different from the Trust Score?

The Trust Score is a single composite number summarising overall communication credibility. The Credibility Signal is the per-second timeline that shows how that score moves across the communication. The Trust Score tells you the outcome; the Credibility Signal tells you exactly when and where the problem occurs — enabling targeted rehearsal rather than general coaching.

What causes a credibility drop in the Credibility Signal?

Common causes of credibility drops identified by EchoDepth include: vocal hesitation on specific phrases (particularly guidance or projection statements), delivery inconsistency when switching between prepared and unprepared content, micro-expressions inconsistent with the verbal message, increased speech pace under pressure, and upward inflection on declarative statements.

Where is the Credibility Signal most used?

The Credibility Signal is most commonly used in three contexts: earnings call and investor presentation preparation (identifying where guidance delivery loses conviction), sales demo coaching (showing where buyer engagement drops during the pitch), and change management communications (identifying where leadership credibility breaks down before programme launch).

Q: What is a Credibility Signal?

A Credibility Signal is EchoDepth's per-second delivery quality timeline — a timestamped chart showing where credibility rises and falls across the full duration of a communication. Unlike the Trust Score (a single composite number), the Credibility Signal shows the exact moment where delivery breaks down, making it the primary coaching tool for high-stakes communication preparation.

The Credibility Signal is EchoDepth's per-second delivery quality timeline. It shows exactly when and where credibility breaks down in a communication — not just that it does.

Definition

A Credibility Signal is a timestamped per-second delivery quality timeline generated by EchoDepth. It maps where delivery credibility rises, holds and drops throughout a communication — identifying the specific moment and cause of every credibility break for targeted coaching.

Credibility Signal vs Trust Score

The two primary EchoDepth outputs work together. The Trust Score tells you the result; the Credibility Signal tells you the reason:

Composite result

Trust Score

A single 0–100 number summarising overall communication credibility. The verdict.

Per-second timeline

Credibility Signal

A timestamped chart showing exactly where credibility rises and falls. The evidence.

What Causes a Credibility Drop?

EchoDepth identifies the specific delivery pattern causing each drop in the Credibility Signal. The most common causes:

Vocal hesitation on guidance statements

The most common cause in earnings calls. When delivery pace slows or hesitation markers appear on forward-looking statements, the signal drops sharply.

Upward inflection on declarative content

Stating facts with rising intonation signals uncertainty. Common in sales demos when reps haven't fully internalised the content.

Micro-expression inconsistency

Facial delivery signals that contradict the verbal message — the most visible cause of credibility breaks in leadership communications.

Delivery pace increase under pressure

Speeding up during complex sections signals cognitive load or discomfort. Common in Q&A sections and objection handling.

Content-delivery misalignment

Where the language is confident but the delivery signals are not — the gap between what is said and what audiences read.

Common Questions

How is the Credibility Signal used in earnings call preparation?

Finance teams run rehearsal recordings through EchoDepth. The Credibility Signal timeline identifies the exact timestamps where guidance delivery loses conviction — typically on forward-looking statements and guidance revision moments. Teams revise delivery at those specific points and re-score. The process typically requires 2–3 rehearsal iterations to raise the Credibility Signal to an acceptable level across the full call.

Can the Credibility Signal be tracked across multiple sessions?

Yes. EchoDepth tracks Credibility Signal trends across rehearsal sessions and live deployments. Improvement in the Credibility Signal timeline at specific timestamps is the primary indicator that coaching interventions are working — more actionable than a Trust Score alone.

What format is the Credibility Signal delivered in?

The Credibility Signal is delivered as a timestamped PDF chart in the standard EchoDepth report, and as structured JSON via API for integration into dashboards, CRM and governance systems. Each point in the timeline corresponds to a specific second in the source content.
