1. A communication support system that supports communication by speech between a user in a first area and a user in a second area in an automobile, the communication support system comprising:
a first area microphone that is disposed in the first area;
a second area speaker that is disposed in the second area;
a road noise detection unit that is configured to detect whether a large road noise is being generated;
a control unit; and
a voice processing unit that is configured to relay a voice picked up by the first area microphone to the second area speaker;
wherein the control unit is configured to:
cause the voice processing unit to extract a component of a standard band that is a preset frequency band of the voice picked up by the first area microphone and to relay the extracted component to the second area speaker, during a period in which the road noise detection unit does not detect that the road noise is being generated, and
cause the voice processing unit to extract a component of a treble band, which is a preset frequency band that does not include at least a band on a low frequency side of the standard band but includes a band having a higher frequency than the standard band of the voice picked up by the first area microphone and to relay the extracted component to the second area speaker, during a period in which the road noise detection unit detects that the road noise is being generated.
