and when the volume of the one participant is differentially increased, play back at least a portion of recorded speech of the one participant that includes the context data. ### Claim 6 (depends on 1) The device of claim 1, wherein the controller is further configured to: link a related talkgroup, with the talkgroup, based on respective context data of a respective participant in the related talkgroup; and differentially increase respective volume of the respective participant, relative to one or more of the other participants in the talkgroup and the related talkgroup. ### Claim 7 (depends on 1) The device of claim 1, wherein the controller is further configured to: differentially change the volume, in the talkgroup, of one or more participants, of the plurality of participants, relative to the other participants, of the plurality of participants, as the current biometric data indicates the stressed state of the given user is increasing or decreasing in stress. ### Claim 8 (depends on 7) The device of claim 7, wherein the controller is further configured to: increase a number of the participants whose volume is differentially increased as the stressed state is decreasing in stress; and decrease the number of the participants whose volume is differentially increased as the stressed state is increasing in stress. ### Claim 9 (depends on 1) The device of claim 1, wherein the context data includes one or more of: respective locations of one or more of the plurality of participants; a respective frequency of speaking of one or more of the plurality of participants; keywords spoken by one or more of the plurality of participants; a respective conversation with the given user by one or more of the plurality of participants a sequence of the respective conversation with the given user by one or more of the plurality of participants; respective sensor data associated with one or more of the plurality of participants; and respective roles of one or more of the plurality of participants. ### Claim 10 (depends on 1) The device of claim 1, wherein the given user is a dispatcher participating in a plurality of talkgroups, including the talkgroup, and the controller is further configured to: when a comparison of the current biometric data of the given user with the historical biometric data indicates that the given user is in the stressed state: determine a primary talkgroup, from the plurality of talkgroups, based on respective context data of the plurality of talkgroups; and control a display screen associated with the dispatcher to differentially increase a relative size of a user interface of the primary talkgroup, relative to respective user interfaces other talkgroups of the plurality of talkgroups. ### Claim 11 A method comprising: determining, at a controller, that a given user is communicating in a talkgroup that includes a plurality of participants different from the given user, the controller having access to a memory storing historical biometric data indicative of stress for the given user; and when a comparison of current biometric data of the given user with the historical biometric data indicates that the given user is in a stressed state: differentially increasing, using the controller, volume in the talkgroup, of one participant, of the plurality of participants, relative to other participants of the plurality of participants, based on context data of one or more of the talkgroup and the plurality of participants. ### Claim 12 (depends on 11) The method of claim 11, further comprising: differentially increasing the volume of the one participant, relative to the other participants, at least at a communication device of the given user. ### Claim 13 (depends on 11) The method of claim 11, further comprising: differentially increasing the volume of the one participant, relative to the other participants, by one or more of: increasing the volume of the one participant and lowering the volume of the other participants. ### Claim 14 (depends on 11) The method of claim 11, further comprising: differentially increasing the volume in the talkgroup of a second participant, of the plurality of participants in the talkgroup, relative to the other participants of the plurality of participants, based on the context data. ### Claim 15 (depends on 11) The method of claim 11, further comprising: recording speech in the talkgroup, the speech including the context data; and when the volume of the one participant is differentially increased, playing back at least a portion of recorded speech of the one participant that includes the context data. ### Claim 16 (depends on 11) The method of claim 11, further comprising: linking a related talkgroup, with the talkgroup, based on respective context data of a respective participant in the related talkgroup; and differentially increasing respective volume of the respective participant, relative to one or more of the other participants in the talkgroup and the related talkgroup. ### Claim 17 (depends on 11) The method of claim 11, further comprising: differentially changing the volume, in the talkgroup, of one or more participants, of the plurality of participants, relative to the other participants, of the plurality of participants, as the current biometric data indicates the stressed state of the given user is increasing or decreasing in stress. ### Claim 18 (depends on 17) The method of claim 17, further comprising: increasing a number of the participants whose volume is differentially increased as the stressed state is decreasing in stress; and decreasing the number of the participants whose volume is differentially increased as the stressed state is increasing in stress. ### Claim 19 (depends on 11) The method of claim 11, wherein the context data includes one or more of: respective locations of one or more of the plurality of participants; a respective frequency of speaking of one or more of the plurality of participants; keywords spoken by one or more of the plurality of participants; a respective conversation with the given user by one or more of the plurality of participants a sequence of the respective conversation with the given user by one or more of the plurality of participants; respective sensor data associated with one or more of the plurality of participants; and respective roles of one or more of the plurality of participants. ### Claim 20 (depends on 11) The method of claim 11, wherein the given user is a dispatcher participating in a plurality of talkgroups, including the talkgroup, and the method further comprises: when a comparison of the current biometric data of the given user with the historical biometric data indicates that the given user is in the stressed state: determining a primary talkgroup, from the plurality of talkgroups, based on respective context data of the plurality of talkgroups; and controlling a display screen associated with the dispatcher to differentially increase a relative size of a user interface of the primary talkgroup, relative to respective user interfaces other talkgroups of the plurality of talkgroups.
