Communication is large percentage of program execution as the program manager must communicate with the appropriate stakeholders. In larger programs face-to-face communication is not always possible. When emails are used what verbal aspect of communication is lost?

Paralingual communication refers to the vocal aspects of speech that are separate from the actual words used. This includes elements like tone of voice, pitch, volume, and inflection. These cues convey emotion, emphasis, and sincerity, adding a critical layer of meaning to verbal communication. When using text-based methods like email, these paralingual cues are completely lost. The recipient cannot hear the sender's tone or inflection, which can easily lead to misinterpretation of the message's intent and emotional context, a significant risk in complex program stakeholder communications.

A. Barriers: Barriers are obstacles that hinder effective communication (e.g., language, culture), not a component of the verbal message itself.
B. Noise: Noise is any interference in the communication channel that distorts the message, not an inherent aspect of verbal communication.
C. Nonverbal: Nonverbal communication includes body language and facial expressions. While also lost in email, it is distinct from the verbal aspects of communication, which is what the question specifically asks about.

1. Project Management Institute. (2017). The Standard for Program Management (4th ed.). Section 5.4, Program Communications Management, discusses the selection of communication methods. It notes that face-to-face communication is preferred for sensitive topics because it "allows for the observation of body language and tone of voice," implicitly acknowledging that text-based methods lack these paralingual elements (p. 87).

2. Mehrabian, A. (1981). Silent Messages: Implicit Communication of Emotions and Attitudes (2nd ed.). Wadsworth. This foundational work in communication studies breaks down the components of a message, attributing significant meaning to vocal cues (38%)—what is now termed paralinguistics—separate from the words themselves (7%) and nonverbal body language (55%). This highlights that paralingual cues are a distinct and critical part of communication lost in text.

This peer-reviewed article details how text-based media like email are "lean" because they filter out crucial paralinguistic cues (e.g., tone of voice, volume, inflection) and nonverbal cues, increasing the likelihood of miscommunicating emotional intent (p. 311).
