Have you ever received a pleasant call? If so, congratulations.

However, in Scientology, words, speech and talk is no communication.
In Scientology, Communication is the key to establish Affinity and Agreements (Reality) at some point on the Tone-Scale of Human Emotions. Communication consists of 57 different Perception, which is an Energy backed up by Force, such as for example the pleasure of the sun's energy on a beach or the pain from a burnt finger. The E-meter assists in interpreting any Communication to reach an Understanding, and then Knowledge is gained when you Look. Basically, a Scientologist is an observer, and that is to communicate.
