Abstract
A communication system includes a processor and a computer readable medium, coupled with the processor, comprising instructions that program the processor to: cause an electromagnetic emitter to irradiate a location on a selected object in proximity to a speaker; determine, from radiation reflected by the selected object at the irradiated location, an audio characteristic of the irradiated location; and when the audio characteristic is acceptable, assigning an electromagnetic microphone to collect audio information from radiation reflected by the selected object at the irradiated location.
