VOX

In telecommunication, a vox (short for 'voice operated switch') is a switch that operates when sound over a certain threshold is detected. It is usually used to turn on a transmitter or recorder when someone speaks. It is used instead of a push-to-talk button on transmitters or to save storage space on recording devices. The circuitry usually includes a delay that leaves the circuit activated when the sound stops. This keeps the circuit from turning off during short pauses in speech.

In audio recording and sound reinforcement, the term 'vox' may be used as an abbreviation for 'voice', 'vocal track', or 'vocal channel', primarily because it is the nominative form of "voice" in latin.
