Source audio identifiers for digital communications

1. A method comprising:

receiving a digital communication from a sender directed to a recipient;

determining whether the digital communication is associated with an audio identifier that identifies the sender;

accessing communication exchange preferences associated with the recipient;

determining whether the communication exchange preferences have been setup to handle audio identifiers for digital communications from the sender;

if the communication exchange preferences have been setup to handle audio identifiers for digital communications from the sender, rendering of the audio identifier prior to or concurrent with presentation of the digital communication for perception by the recipient; and

if the communication exchange preferences have not been setup to handle audio identifiers for digital communication from the sender,

rendering a call notification user interface for perception by the recipient in response to the digital communication; and

conditioning the rendering of the audio identifier on whether the recipient, through interactions with the call notification user interface, enables the audio identifier designated by the sender to be rendered for digital communications from the sender.

2. The method of claim 1 , wherein the audio identifier is a spoken version of a user identifier of the sender.

3. The method of claim 1 , wherein the audio identifier includes a first sound designated by the sender concatenated with a second sound not designated by the sender.

4. The method of claim 3 , wherein the second sound is designated by the recipient.

5. The method of claim 1 , wherein the audio identifier includes a first sound designated by the sender concatenated with a second sound that identifies a group to which the sender belongs.

6. The method of claim 5 , wherein the group to which the sender belongs is a job group, an organization to which the sender belongs or works, or a buddy group in an instant messaging buddy list of the recipient.

7. The method of claim 1 , wherein the audio identifier includes a first sound designated by the sender concatenated with a second sound that identifies a location from which the sender is sending.

8. The method of claim 1 , wherein the audio identifier includes a first sound designated by the sender concatenated with a second sound that identifies an urgency or importance of the digital communication.

9. The method of claim 1 , wherein the audio identifier includes a first sound designated by the sender concatenated with a second sound that indicates whether the sender is currently online.

10. The method of claim 1 , wherein determining whether the digital communication is associated with an audio identifier comprises determining whether an audio identifier has been received from the sender.

11. The method of claim 10 , wherein determining whether the audio identifier has been received from the sender comprises determining whether the audio identifier has been received in an MMS or SMS message prior to or concurrent to receiving the digital communication.

12. The method of claim 10 , wherein determining whether an audio identifier has been received from the sender includes determining whether the audio identifier has been received with the digital communication.

13. The method of claim 1 , wherein the rendering of the audio identifier is allowed when communication exchange preferences of the recipient explicitly include a setting indicating that the recipient is allowed to perceive the audio identifier.

14. The method of claim 13 , wherein the setting is set by the recipient in response to a query.

15. The method of claim 1 , wherein the rendering of the audio identifier is not allowed when the communication exchange preferences explicitly include a setting indicating that the recipient is not allowed to perceive the audio identifier.

16. The method of claim 15 , wherein the setting is set by the recipient in response to a query.

17. The method of claim 1 , further comprising:

before rendering the call notification user interface, playing, in response to the digital communication, a special ring tone indicating to the recipient that the digital communication is associated with an audio identifier designated by the sender and that no communication exchange preferences have been setup for digital communications from the caller.

18. The method of claim 1 , wherein the rendering of the audio identifier also is conditioned on whether the recipient is available to receive the digital communication.

19. The method of claim 1 , further comprising rendering for perception by the recipient a sender profile.

20. A computer system comprising:

a data store configured to store audio identifiers; and

a digital communication processor configured to:

receive a digital communication from a sender directed to a recipient,

determine whether the digital communication is associated with an audio identifier that identifies the sender;

access communication exchange preferences associated with the recipient;

determine whether the communication exchange preferences have been setup to handle audio identifiers for digital communications from the sender;

if the communication exchange preferences have been setup to handle audio identifiers for digital communications from the sender, access the audio identifier from the data store and render the audio identifier prior to or concurrent with presentation of the digital communication for perception by the recipient; and

if the communication exchange preferences have not been setup to handle audio identifiers for digital communication from the sender,

render a call notification user interface for perception by the recipient in response to the digital communication; and

condition the rendering of the audio identifier on whether the recipient, through interactions with the call notification user interface, enables the audio identifier designated by the sender to be rendered for digital communications from the sender.

21. An apparatus comprising:

means for receiving a phone call from a caller directed to a recipient;

means for determining whether the phone call is associated with an audio identifier that identifies the caller and that is designated by the caller;

means for accessing communication exchange preferences associated with the recipient;

means for determining whether the communication exchange preferences have been setup to handle audio identifiers for digital communications from the sender;

if the communication exchange preferences have been setup to handle audio identifiers for digital communications from the sender, means for rendering of the audio identifier prior to or concurrent with presentation of the digital communication for perception by the recipient; and

if the communication exchange preferences have not been setup to handle audio identifiers for digital communication from the sender,

means for rendering a call notification user interface for perception by the recipient in response to the digital communication; and

means for conditioning the rendering of the audio identifier on whether the recipient, through interactions with the call notification user interface, enables the audio identifier designated by the sender to be rendered for digital communications from the sender.
