Voice procedure

From Free net encyclopedia

Voice procedure refers to techniques used to clarify, simplify and standardize spoken communications over two-way radios, in use by the military, in civil aviation, police and fire dispatching systems, citizens' band radio, etc.

Voice procedure is intended to maximise clarity of spoken communication and reduce misunderstanding. It consists of signalling protocol such as the use of 'over', 'roger' and 'stand by'; use of so-called phonetic alphabet words like 'alpha', 'bravo', 'charlie'; abbreviated codes like the CB radio ten-code, Q Codes in amateur radio and aviation, police codes, etc.; and jargon.

Some elements of voice procedure are understood across many applications, but significant variations exist. The military of the NATO countries have similar procedures in order to make cooperation easier, and pseudo-military organisations often base their procedures on them, so some commonality exists there. On the other hand, some elements of police codes are not necessarily standardized even within the same jurisdiction, and using the less familiar codes can defeat the purpose of good communication.

Words in voice procedure

Some words with specialised meanings are used in radio communication throughout the English-speaking world, and in international radio communications, where English is the lingua franca.

  • Over - I have finished talking and I am listening for your reply.
  • Out or Clear- I have finished talking to you and do not expect a reply
  • Roger - I understand what you just said (after receiving information)
  • Wilco - I will do as you said (after receiving new directions).

The combination "Roger, Wilco" is a commonly used to affirm one understands that the last call did not only contain information, but a clear directive, as well. The accurate translation would be "Received, Will Comply".

While popular, "Over and out" is somewhat nonsensical, since the two statements actually contradict each other.
