Claim 0:
1. A computer-implemented method comprising: detecting a plurality of external sound signals; determining that at least two of the external sound signals comprise speech from a first person and speech from a second, different person, based on one or more vocal or auditory characteristics of the first person's speech or of the second person's speech as detected by at least one microphone;
determining that an amplitude value associated with the speech of the second person is to be reduced by sound cancellation, wherein the speech of the first person remains at an initial amplitude value;
determining a direction from which the second person's speech is received, wherein the at least one microphone that detects the second person's speech is physically oriented from a first direction to the determined direction; and
applying sound cancellation in the determined direction to reduce the amplitude of the second person's speech as detected by the microphone, while allowing the speech of the first person to remain at the initial amplitude value.
