The latter falls under the umbrella term teleconference. A teleconference is an electronic meeting between two or more sites. It can range from an audioconference, where you hold an interactive conversation, to a videoconference, where video information can also be exchanged.
Auditory scene reproduction for tele-operated robot systems

Virtual auditory scene synthesis technology has been widely applied in game applications, whereas there are few social media applications, such as tele-presence robots, using such techniques to reproduce spatial auditory scene. There are some studies suggested to modify the loudness of the tele-operator's voice using the noise level in the robot's environment and the distance between robot and interlocutors [12,13]. Rich auditory sense is a factor that cannot be ignored for improving quality and ease of interaction in tele-communication applications. Playing binaural recorded sounds using stereo headphones is the simplest idea and also a common way to reproduce an auditory scene. However, this method requires very specific recording setup, and also loses dynamic cues corresponding to tele-operator's movements and the ability to rearrange sounds from different locations. The use of microphone array techniques is an efficient way to store characteristic information corresponding to spatial properties. There are many teleconference-related studies using microphone arrays for various purposes such as localizing sound sources [14], separating the sound from a target direction [15], or suppressing echo [16]. However, these systems are not dealing with the auditory scene reproduction problem and their output remain monaural.
