The term used to describe a combined microphone and transmitter designed to capture conversations is a "bug." This device typically consists of a small microphone that can pick up audio and a transmitter that sends that audio to a receiver. Bugs are often used in covert surveillance and investigative contexts to secretly listen to conversations without the knowledge of the individuals being recorded.

The functionality of a bug distinguishes it from other options. An intercom is primarily a communication system used within a premise rather than for covert operations. While "spy device" is somewhat of a broad term that could potentially include bugs, it does not specify the unique function of capturing audio covertly. A listening post generally refers to a stationary location set up for surveillance or monitoring, rather than a mobile unit that captures conversations directly. Thus, "bug" is the most accurate and specific term for this type of listening device.
