Identifying a voice command boundary

A computer program product for augmenting communication, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:

• calculate a first sound boundary that represents a predicted maximum distance at which a communication can be understood;
• calculate a second sound boundary that represents a predicted maximum distance at which the communication can be heard;
• predict an intended recipient from among a plurality of people in a location, wherein the prediction includes:
• determining a direction of the communication;
• and
• analyzing content of the communication;
• determine that the intended recipient cannot understand the communication based on the first sound boundary and a location of the intended recipient, and in response:
• superimpose a graphical indication over a view of a locale from a perspective of a user indicating that the intended recipient cannot understand the communication;
• and
• automatically electronically transmit the communication to the intended recipient;
• and
• determine that an unintended recipient may be able to hear the communication based on the second sound boundary and a location of the unintended recipient, and in response, superimposing a graphical indication over a view of the locale from a perspective of a user indicating that the unintended recipient can hear the communication;
• wherein calculating the first sound boundary and the second sound boundary comprises:
• measuring a volume level of the communication;
• measuring a level of ambient noise in the locale;
• and
• calculating a sound attenuation rate based on one or more environmental factors at the locale.

An augmented reality system, comprising:

• a wearable frame;
• a processor coupled to the wearable frame, wherein the processor calculates a sound boundary within which a communication can be heard;
• and
• a display coupled to the wearable frame, wherein the display overlays a visualization of the sound boundary onto a field of view of a user.
