Abstract:
Nonverbal communication units function as essential complements to verbal
language, often providing additional layers of meaning or regulating the flow of conversation.
This study aims to classify the communicative functions of nonverbal units within the speech
process. Through discourse analysis of recorded dialogues and presentations, the study
identifies primary roles such as emphasis, emotional expression, turn-taking, and
contradiction. The classification system developed highlights the multifunctional nature of
nonverbal elements and emphasizes their relevance in effective communication.
Keywords
: speech process, nonverbal communication, function analysis, gesture
classification, discourse.
Introduction
While spoken words convey content, nonverbal units often convey emotion, attitude, and
intent. Understanding how these units operate functionally within the speech process is
essential for improving clarity, engagement, and rapport in both formal and informal
communication contexts.
Literature Review
Birdwhistell (1970) was among the first to assert that over 65% of communication is
nonverbal. Ekman and Friesen’s typology (1969) has become foundational in identifying
gesture functions. McNeill (1992) introduced the idea that gestures form a unified system with
speech rather than operating separately. Recent discourse-based studies have emphasized the
regulatory and interactional nature of nonverbal cues (Kendon, 2004).
Methods
This research applies a
mixed-methods approach
, primarily qualitative but supported
by frequency-based quantitative data. The aim is to examine and classify the communicative
functions of nonverbal units within various types of speech events.
3.1. Research Design
A
functional discourse analysis
was conducted to observe and categorize the roles
played by nonverbal units in real-time communication. The study emphasizes contextually
grounded interaction.
3.2. Data Corpus
The data corpus consisted of
40 recorded speech events
, including:
10 classroom lectures
10 job interview simulations
10 casual peer conversations
10 televised or online public speeches
Each sample lasted 3–5 minutes and involved speakers from diverse linguistic
backgrounds (L1 English, Uzbek, Russian).

3.3. Annotation and Transcription
All recordings were transcribed using
multimodal annotation conventions
that
marked:
Kinesic signals (hand, arm, head, div gestures)
Facial expressions (eyebrows, eye movement, mouth positioning)
Paralinguistic cues (pauses, intonation patterns)
The transcription also included timestamps to capture the timing of gestures relative to
verbal content.
3.4. Classification Framework
Nonverbal units were analyzed and categorized based on the
Ekman-Friesen five-
function model
:
1.
Emblems
2.
Illustrators
3.
Affect displays
4.
Regulators
5.
Adaptors
Functional coding was performed manually and reviewed with support from discourse
analysis software (
ELAN
and
NVivo
) to ensure coding consistency and trace gesture-speech co-
occurrence.
3.5. Validation and Reliability
Triangulation was used to ensure data validity:
Comparison across different contexts (formal vs. informal)
Peer review of gesture classification
Participant feedback for accuracy in gesture interpretation
Inter-coder reliability was achieved through parallel coding by two analysts, reaching
over
90% agreement
on gesture functions.
Results
Five core communicative functions of nonverbal units were confirmed:
1.
Emphasis
: Stressing particular verbal points (e.g., fist when saying "very important").
2.
Emotional Display
: Displaying internal states (e.g., raised eyebrows = surprise).
3.
Regulation
: Managing turn-taking (e.g., hand raise = desire to speak).
4.
Illustration
: Depicting concepts (e.g., outlining size/shape with hands).
5.
Contradiction
: Disagreeing with verbal content (e.g., saying “I’m fine” while looking
down).
Notably, regulatory gestures were most frequent in formal settings, while emotional and
adaptor gestures were dominant in informal contexts.
Discussion
Nonverbal units are deeply integrated into the speech process. They not only reflect
speaker intent but also serve metacommunicative purposes—commenting on the
communication itself. Misinterpretation of these cues, especially across cultures, can lead to
breakdowns in communication. The multifunctionality of gestures underscores the need for
multimodal competence in education and public speaking.
Conclusion
Understanding the communicative functions of nonverbal units enhances both
comprehension and expression in spoken discourse. Classifying these functions aids educators,

translators, and communicators in better adapting their strategies to audience needs.
Nonverbal literacy should be taught alongside verbal skills in modern communication training.
