2. Types of Communication  Verbal Communication  Non verbal Communication  Vocal Communication

3. What is communication? Communication is the imparting or interchange of thoughts, opinions, or information by speech, writing, or signs.

4. Verbal communication expressed in spoken words; oral rather than written: Verbal communication components include; speech, intonation, tone, clarity, emphasis, repetition, sound, translator which are most often used in day-to-day verbal communication. For example two persons are having a conversation; the air is the medium, language is the encoder/decoder, and the persons act as source and receiver. However, if one person speaks German and the other person speaks English then a third person, a German to English translator would serve as the decoder and encoder. (Jones; Kovac, 2003, pp. 1-2) as the picture explains.

6. Non Verbal Communication Those aspects of communication, such as gestures and facial expressions, that do not involve verbal communication but which may include nonverbal aspects of speech itself (accent, tone of voice, speed of speaking, etc.) Components of non-verbal communication include visibility, emotions, actions/gestures, listening, and written which are the most common types used depending on context of human communication. For example: when one person communicates through their eyes to another person, winking to convey approval, and verbal communication is not used, nor is it necessary then.

8. Vocal Communication Inclined to express oneself in words, especially copiously or insistently. Significant differences between nonvocal and vocal communication are matters more of degree than of kind. Signs, signals, symbols, and possibly icons may, at times, be easily verbalized, although most people tend to think of them as visual means of expression.
