Presentation Anxiety Glossary

Every key term in presentation anxiety, speaking science, and AI coaching — defined clearly, without jargon.

Quick Answer

EchoPitch's glossary defines 36 key terms spanning presentation anxiety, public speaking science, and AI coaching, organized into seven categories: Condition, Physiology, Treatment, Psychology, Delivery, Cognitive, and AI / EchoPitch. Delivery terms, such as pitch range, pauses and filler words, define how a voice comes across. Condition terms include glossophobia (fear of public speaking, the most commonly reported social fear), presentation anxiety, social anxiety disorder, rejection sensitive dysphoria, and erythrophobia. Physiology terms explain the biological mechanisms behind anxiety symptoms, such as the fight-or-flight response, adrenaline, cortisol, and the vagus nerve. Treatment terms cover evidence-based approaches like systematic desensitisation, cognitive behavioural therapy, and beta-blockers such as propranolol. Cognitive terms address working memory and procedural memory under stress. AI / EchoPitch terms define the technical methods EchoPitch itself uses, including the Facial Action Coding System and the VAD emotional model. Each definition is written in plain language without jargon, letting readers look up any presentation-anxiety concept quickly.

Condition

Glossophobia
The clinical term for fear of public speaking. From the Greek glossa (tongue) and phobos (fear). The most commonly reported social fear: about one US adult in five reports a lifetime fear of public speaking (Ruscio et al., 2008). Classified as a specific social phobia under DSM-5.
Presentation anxiety
Situational anxiety triggered by the prospect or act of presenting. Manifests as physical symptoms (shaking, sweating, nausea), cognitive symptoms (mind going blank, catastrophic thinking), and behavioural symptoms (avoidance, over-preparation).
Social anxiety disorder
A DSM-5 anxiety disorder involving intense fear of social situations involving scrutiny or negative evaluation. Broader than glossophobia — affects multiple social contexts. Lifetime prevalence ~13%. Highly treatable with CBT and/or medication.
Rejection sensitive dysphoria
An intense emotional response to real or perceived rejection, criticism, or failure. Common in ADHD. Makes the evaluative element of presentations feel genuinely devastating rather than merely uncomfortable.
Erythrophobia
A specific phobia characterised by fear of blushing. When anxiety about blushing becomes so severe it causes avoidance of social situations, it may meet diagnostic criteria for erythrophobia — a form of social anxiety disorder.

Physiology

Fight-or-flight response
The physiological stress response triggered when the brain perceives social threat. Releases adrenaline and cortisol, causing elevated heart rate, shallow breathing, and muscle tension — all common presentation symptoms. Controlled by the sympathetic nervous system.
Adrenaline (epinephrine)
A hormone released during fight-or-flight. Causes increased heart rate, dilated pupils, and vasodilation near the skin surface — the mechanism behind blushing. Also tightens laryngeal muscles, causing voice shaking and cracking.
Cortisol
The primary stress hormone. High cortisol temporarily impairs hippocampal memory retrieval — the mechanism behind blanking out during presentations. Also contributes to stomach symptoms and voice tension.
Autonomic nervous system
Controls involuntary bodily functions including heart rate, digestion, and blood vessel dilation. Consists of the sympathetic (fight-or-flight) and parasympathetic (rest-and-digest) divisions. Most physical anxiety symptoms are autonomic responses.
Parasympathetic nervous system
The calming division of the autonomic nervous system. Activated by slow, extended-exhale breathing. Counteracts fight-or-flight. The physiological mechanism through which breathing exercises reduce anxiety.
Vagus nerve
The primary nerve of the parasympathetic nervous system, running from the brainstem to the gut. Directly stimulated by slow, extended-exhale breathing. Why breathing exercises reduce anxiety rapidly.
Vasodilation
Widening of blood vessels. In blushing, adrenaline causes cutaneous vasodilation — widening of vessels near the skin surface in the face, neck and chest, increasing blood flow and producing visible redness.
Laryngeal tension
Tightness in the larynx (voice box) muscles caused by stress. Disrupts smooth vocal cord vibration, producing voice shaking, cracking, or a thin, strained quality during presentations.

Treatment

Systematic desensitisation
An evidence-based treatment for specific phobias involving graduated exposure to feared situations in order of increasing difficulty. Repeated non-threatening exposure teaches the brain the stimulus is not genuinely dangerous.
Cognitive behavioural therapy (CBT)
The gold-standard psychological treatment for anxiety disorders. Targets cognitive distortions (catastrophising, mind-reading, all-or-nothing thinking) combined with behavioural experiments to test and correct those beliefs.
Beta-blockers (propranolol)
Medication that blocks adrenaline receptors, preventing physical symptoms of anxiety (racing heart, trembling, blushing, voice tension) without sedation. Prescription-only. Used off-label for performance anxiety in the UK.
Exposure practice
Repeatedly doing the feared thing, in manageable steps, until it feels less threatening. For speaking, that means starting with recording yourself, then a small trusted audience, then larger or higher-stakes settings. It is the practical core of systematic desensitisation.

Psychology

Anticipatory anxiety
Worry about a future event, felt before it happens. For many people the days before a presentation are worse than the presentation itself. Rehearsal and exposure reduce it because the event becomes familiar.
Spotlight effect
The tendency to overestimate how much other people notice and remember about us. Studies by Gilovich and colleagues (2000) found people greatly overestimated how many others noticed an embarrassing T-shirt. Audiences notice far less of your nervousness than you expect.
Cognitive reappraisal
Deliberately re-interpreting a feeling. Brooks (2014) found that people who told themselves “I am excited” before a speech or performance task did better than those who tried to calm down, because excitement and anxiety share the same arousal. Often called the “excited, not nervous” reframe.
Physiological sigh
A breathing pattern of two inhales through the nose followed by one long exhale through the mouth. A 2023 randomised study by Balban and colleagues found that a few minutes of daily cyclic sighing improved mood and reduced breathing rate more than mindfulness meditation. It is a quick way to settle before you speak.
Safety behaviours
Things anxious speakers do to avoid feeling exposed: reading from slides, gripping the lectern, avoiding eye contact, over-scripting. They reduce anxiety in the moment but stop you learning that you can cope without them, so they tend to keep the fear going.

Delivery

Pitch range
The gap between the higher and lower notes in your speech, usually measured in semitones. As a rule of thumb, under about 4 semitones tends to sound flat and 8 to 12 sounds lively. EchoPitch’s free voice analyzer reports it and flags a monotone result.
Semitone
The smallest step on a piano keyboard and the standard unit for comparing pitch. Twelve semitones make an octave. Measuring pitch in semitones rather than hertz lets low and high voices be compared fairly.
Monotone
Speech with very little pitch movement. Listeners tend to hear it as bored, uncertain or rehearsed, and it makes key points harder to pick out. The usual fix is to stress one key word per sentence and let pitch fall at the end of statements.
Prosody
The rhythm, stress and intonation of speech: everything about how something is said apart from the words. Pace, pauses, pitch movement and loudness are all parts of prosody.
Speaking rate (words per minute)
How many words you say per minute. Conversational speech for most people sits somewhere around 120 to 160 words per minute. Nervous speakers tend to speed up, which cuts pauses and makes content harder to follow. Slower is usually safer than faster for complex material.
Filler words
Sounds and words such as “um”, “uh”, “like” and “you know” that fill a gap while you think. A few are normal and not harmful. They become distracting when they cluster before every point. Replacing a filler with a short silence is the standard fix.
Pause
A silence between phrases. Short pauses let listeners absorb a point and give you time to think. EchoPitch’s voice analyzer counts every silence longer than 250 milliseconds, and reports the average length, the longest, and how much of your time is spent actually speaking.
Volume consistency
How much your loudness varies from phrase to phrase. Variation of about 2 to 6 dB sounds natural. Much less sounds very even and flat; much more sounds uneven. Trailing off, where the end of a sentence fades, is the most common problem.
Uptalk
Raising pitch at the end of a statement so it sounds like a question. Occasional use is normal. Used constantly it can make you sound unsure about your own point. Ending statements with a falling pitch sounds more certain.
Trailing off
Letting volume and energy fade at the end of a sentence, so the last words are lost. Common when nervous or when thinking about the next point. Finishing sentences at the same volume you started them fixes most of it.

Cognitive

Working memory
Short-term cognitive storage for information currently in active use. Impaired by ADHD and by high cortisol under stress. During presentations, holds your structure, your position in it, and the words you're about to say simultaneously.
Procedural memory
Memory for skills and habitual actions. More resistant to stress impairment than declarative memory. Deliberate practice moves presentation delivery from declarative to procedural memory, reducing cognitive load under pressure.

AI / EchoPitch

FACS — Facial Action Coding System
A system for describing facial movement as combinations of Action Units, each tied to a specific muscle group. Developed by Paul Ekman and Wallace Friesen. The full system defines 44 Action Units; EchoPitch tracks a subset of 17 of them (such as brow raise, lip corner pull and jaw drop) to measure tension and expression during practice sessions. It measures movement, not what a person is feeling.
VAD model
Valence-Arousal-Dominance — a three-dimensional model of emotional state. Valence (positive/negative), Arousal (calm/excited), Dominance (in control/out of control). Used by EchoPitch to track emotional state changes during practice.
