System and method for voice user interface navigation
View Patent ↗A Voice User Interface (VUI) or Interactive Voice Response (IVR) system utilizes three levels of navigation (e.g. Main Menu, Services, and Helper Commands) in presenting information units arranged in sets. The units are “spoken” by a system in a group to a human user and the group of information at each level is preceded by a tone that is unique to the level. When navigating the levels, the tones of the levels are in a musical progression, e.g. the three-note blues progression I, IV, V, for preceding the groups of information, respectively. The musical progression returns to the tonic of the musical key when the navigation returns to the level one of the first group of information.
1. A method for interfacing with a user through a voice user interface (VUI), comprising:
designating a first tonality to a first information level;
designating a second tonality to a second information level;
receiving, through the VUI, a command for information associated with one of the first information level and the second information level;
determining a corresponding one of the tonalities based on the information level associated with the command; and
transmitting the information in the corresponding tonality to the user through the VUI for navigation between the information levels.
2. A method of claim 1 , wherein the tonalities correspond to a musical progression of tones of a musical key.
3. A method of claim 2 , wherein the musical progression starts with the tonic tone of the musical key.
4. A method of claim 1 , wherein the command is a user voice command.
5. A method of claim 1 , wherein each of the tonalities is supplemented with a unique timbre.
6. A method of claim 1 , wherein the information is presented as a voice transmission.
7. An apparatus for interfacing with a user, comprising:
a voice user interface (VUI) configured to designate a first tonality to a first information level, and to designate a second tonality to a second information level,
wherein the VUI is further configured to receive a command for information associated with one of the first information level and the second information level, to determine a corresponding one of the tonalities based on the information level associated with the command, and to transmit the information in the corresponding tonality to the user through the VUI for navigation between the information levels.
8. An apparatus of claim 7 , wherein the tonalities correspond to a musical progression of tones of a musical key.
9. An apparatus of claim 8 , wherein the musical progression starts with the tonic tone of the musical key.
10. An apparatus of claim 7 , wherein the command is a user voice command.
11. An apparatus of claim 7 , wherein each of the tonalities is supplemented with a unique timbre.
12. An apparatus of claim 7 , wherein the information is presented as a voice transmission.
13. An apparatus for interfacing with a user, comprising:
a processor configured to provide a voice portal for transmitting information associated with a plurality of information levels, wherein the information levels correspond to a plurality of tonalities for navigation among the information levels,
wherein the processor is further configured to receive a command for information associated with a one of the plurality of information levels, to determine a corresponding one of the tonalities based on the information level associated with the command, and to transmit the information in the corresponding tonality to the user through the voice portal.
14. An apparatus of claim 13 , wherein the tonalities correspond to a musical progression of tones of a musical key.
15. An apparatus of claim 14 , wherein the musical progression starts with the tonic tone of the musical key.
16. An apparatus of claim 13 , wherein the command is a user voice command, and the information is presented as a voice transmission.
17. An apparatus of claim 13 , wherein each of the tonalities is supplemented with a unique timbre.
18. A method for interfacing with a user through a voice user interface (VUI), comprising:
designating a first tonality to a first information level and a second tonality to a second information level;
determining a corresponding one of the tonalities in response to a command for information; and
transmitting the information in the corresponding tonality to the user through the VUI for navigation between the information levels,
wherein the information levels have a hierarchical relationship, and ascending frequency of the tonalities are associated with the information levels in one direction of the hierarchy and descending frequency of the tonalities are associated with the information levels in another direction of the hierarchy.
19. An apparatus, comprising:
a voice user interface (VUI) configured to designate a first tonality to a first information level, and to designate a second tonality to a second information level,
wherein the VUI is further configured to determine a corresponding one of the tonalities in response to a command for information, and to transmit the information in the corresponding tonality to the user through the VUI, and
wherein the information levels have a hierarchical relationship, and ascending frequency of the tonalities are associated with the information levels in one direction of the hierarchy and descending frequency of the tonalities are associated with the information levels in another direction of the hierarchy.
20. An apparatus, comprising:
a processor configured to provide a voice portal for transmitting information associated with a plurality of information levels, wherein the information levels correspond to a plurality of tonalities for navigation among the information levels,
wherein the processor is further configured to determine a corresponding one of the tonalities in response to a command for information, and to transmit the information in the corresponding tonality to the user through the voice portal, and
wherein the information levels have a hierarchical relationship, and ascending frequency of the tonalities are associated with the information levels in one direction of the hierarchy and descending frequency of the tonalities are associated with the information levels in another direction of the hierarchy.
