Verbal Habits of Deceptive People - Vocal Quality. Voice quality is usually the least reliable indicator, however there are some clues that suggest deception (when found in a cluster of other cues): voice takes a higher pitch, long pauses before speaking, speaking at an overall slower rate with more errors and hesitations ("ums" and "ahs"), and the voice taking on a strained or tense quality. The issue here is that most of these items are subjective, what sounds stressed to one person may not be to another. Listen out for their tempo, tone and volume changes.
