Explanation : There are 8 different types of non-verbal
communication
(a) Social space
(h) Time
(c) Physical characteristics
(d) Body movements
(e) Touch
(f) Paralanguage
(g) Artifacts
(h) Environment
Of these, paralanguage constitutes the following:
(i) Voice quality, e.g., sweet, soft, musical,
cultivated, pleasant, nasty, clear or indistinct,
among other things; it reveals a speaker's
background, mental state, education, sex
and temperament
(ii) Word stress or optimum emphasis on the
right words for right effect
(iii) Intonation or the modulation of the voice
and the shift in stress; e.g., a message with
serious content is delivered in a sombre rather
than high tone.
(iv) Pitch or the vocal slant of the voice; it
reveals the speaker's frame of mind, e.g., an
unusually high pitch may reflect agitation,
an unchanging pitch may get monotonous.
The pitch also indicates the speaker's
social position; e.g., a person in a position
of authority uses a higher pitch than a
subordinate.
(v) Pause which is akin to punctuation in prose;
it introduces variety, and lays emphasis on
a message; used at the wrong place, it may
lead to miscommunication.
(vi) Volume variation of voice to suit the size
of the audience; the larger the audience, the
louder the voice must be to be audible and
effective.
(vii) Mixed signals which occur when the tone,
pitch and facial expressions of the speaker do
not match the spoken words, and confuse the
listener about the speaker's intent; e.g., praise
delivered in a sarcastic tone will amount to
ridicule.
(viii)Overall impression or the speaker's manner,
attitude, dressing style, physical appearance,
etc., which contribute much to the audience
perception.
