2. The one or more portable communication devices of claim 1 , wherein each of the one or more portable communication devices comprises a rigid housing, and the user interface is positioned on the housing.

3. The one or more portable communication devices of claim 1 , wherein the user interface includes one or more of an electronic display, one or more buttons, one or more dials, a touch sensitive display, and an audible speech interface.

4. The one or more portable communication devices of claim 3 , wherein the audible speech interface includes one or more of an audio speaker interface and at least one microphone interface.

5. The one or more portable communication devices of claim 4 , further comprising computer readable instructions stored in the at least one memory, the instructions comprising instructions for carrying out one or more voice initiated processes.

6. The one or more portable communication devices of claim 5 , wherein the one or more voice initiated processes include processes for one or more of voice activated transmission of the audio data, and determination of one or more commands from a voice of the user of the portable communication device.

7. The one or more portable communication devices of claim 6 , wherein the commands include commands for muting the other ones of the portable communication devices, directing the transmitted audio data to only a subset of the other ones of the portable communication devices, and assigning an audible name to one or more of the other ones of the portable communication devices.

8. The one or more portable communication devices of claim 5 , wherein the one or more voice initiated processes include processes for determining a volume of the speech of the user.

9. The one or more portable communication devices of claim 1 , further comprising computer readable instructions stored in the at least one memory of each of the one or more portable communication devices, the instructions comprising instructions for initiating one or more of:

a broadcast-only mode in which the receiving audio data, the mixing, and the transmitting the mixed audio data are disabled;

an open mode allowing communication with devices besides the other ones of the portable communication devices;

a determination of a quality of the received audio data;

a determination of locations of the other ones of the portable communication devices;

a determination of whether one of the other ones of the portable communication devices is out of range or approaching out of range;

a determination of whether one of the other ones of the portable communication devices is turned off;

transmission of a distress signal;

a determination of a motionless state of one of the other ones of the portable communication devices;

a reduction in noise of the received audio data;

an echo reduction;

a generation of a comfort noise; and

a mixing of the received audio data with another audio data stream.

10. The one or more portable communication devices of claim 9 , wherein the another audio data stream is a music stream provided from a locally connected device other than another portable communication device.

11. The one or more portable communication devices of claim 1 , further comprising computer readable information stored in the at least one memory of each of the one or more portable communication devices, the information corresponding to one or more notifications for the user.

12. The one or more portable communication devices of claim 11 , the notifications including one or more of a vibration alert, an illumination of a light, and a visual alert displayed on a display.

13. The one or more portable communication devices of claim 11 , the notifications including an audible alert.

14. The one or more portable communication devices of claim 1 , further comprising computer readable information stored in the at least one memory of each of the one or more portable communication devices, the information corresponding to a voice recording.

15. The one or more portable communication devices of claim 1 , wherein in each portable communication device, the one or more digital processors and the at least one memory are collectively further configured to establish the group with the other ones of the portable communication devices so that the voice communication occurs only between the user of the portable communication device and the other portable communication devices of the group.

16. The one or more portable communication devices of claim 1 , wherein the voice communication further comprises mixing the received audio data from the other ones of the portable communication devices, and the transmitting the received audio data to the user further comprises transmitting the mixed audio data to the user.
