Abstract

There is provided an information processing device to further improve the operability of user interfaces that use a voice as an input, the information processing device including: an acquiring unit configured to acquire context information in a period related to collection of a voice; and a control unit configured to cause a predetermined output unit to output output information related to the collection of the voice in a mode corresponding to the acquired context information.

Claims

1. An information processing device, comprising:

an acquiring unit configured to acquire context information in a period related to collection of a voice, the context information including information of a speed of speech; and

a control unit configured to cause a predetermined output unit to output output information related to the collection of the voice in a mode corresponding to the acquired context information,

wherein the mode corresponding to the acquired context information is a speed-emphasized mode or an accuracy-emphasized mode, and

wherein the acquiring unit, the control unit, and the predetermined output unit are each implemented via at least one processor.

2. The information processing device according to claim 1, wherein the control unit causes the output unit to notify of notification information as the output information in a mode corresponding to a type of process which is executed in accordance with the context information and uses the voice as an input.

3. The information processing device according to claim 2, wherein the control unit controls a search range for converting the collected voice into character information in accordance with the context information.

4. The information processing device according to claim 2, wherein the control unit controls a parameter related to recording of the collected voice in accordance with the context information.

5. The information processing device according to claim 1, wherein the acquiring unit acquires accuracy information related to accuracy of a voice recognition process for the collected voice, and

the control unit causes the output unit to output character information into which the voice is converted as the output information in a mode corresponding to the context information corresponding to the collected voice and the accuracy information corresponding to the voice.

6. The information processing device according to claim 5, wherein the control unit causes the output unit to output each of one or more pieces of the character information into which the voice is converted in a mode based on a comparison result of accuracy information corresponding to the character information and a threshold value, and

the control unit controls the threshold value on a basis of the context information.

7. The information processing device according to claim 6, wherein the control unit causes the output unit to output the character information in which the accuracy information is equal to or less than the threshold value among the one or more pieces of character information into which the voice is converted as character information indicating a pronunciation of a corresponding voice.

8. The information processing device according to claim 6, wherein the control unit causes the output unit to output the character information in which the accuracy information is equal to or less than the threshold value among the one or more pieces of character information into which the voice is converted as character information.

9. The information processing device according to claim 6, wherein the context information indicates a degree of attention of a user related to checking of the character information into which the voice is converted, in which an increased speed of speech indicates an increased degree of attention or in which the location being on the periphery of where character information is output indicates a decreased degree of attention, and

the control unit performs control such that the threshold value increases as the attention decreases.

10. The information processing device according to claim 9, wherein, in a case in which the attention is lower than the threshold value, the control unit causes a predetermined output unit to output the character information as a voice.

11. The information processing device according to claim 5, wherein the control unit presents at least some pieces of the character information presented in a predetermined mode among one or more pieces of the character information into which the voice is converted to be identifiable from the character information presented in a mode different from the predetermined mode.

12. The information processing device according to claim 1, wherein the context information includes information related to a state of an environment in which the voice is collected.

13. The information processing device according to claim 1, wherein the acquiring unit acquires a detection result of the voice included in a collected sound, and

the control unit causes a predetermined output unit to notify of notification information on a basis of the detection result of the voice at least before information based on a result of a voice recognition process for the voice is presented and to output the output information after the notification information is notified of.

17. The information processing device according to claim 1, wherein:

the acquiring unit is further configured to acquire a detection result of a voice included in a collected sound; and

the control unit is further configured to cause the predetermined output unit to notify of notification information on a basis of the detection result of the voice at least before information based on a result of a voice recognition process for the voice is presented.

14. An information processing device, comprising:

a transmitting unit configured to transmit context information in a period related to collection of a voice acquired by a predetermined acquiring unit to an external device, the context information including information of a speed of speech; and

an output unit configured to present output information related to the collection of the voice transmitted from the external device in a mode corresponding to the context information,

wherein the mode corresponding to the context information is a speed-emphasized mode or an accuracy-emphasized mode, and

wherein the transmitting unit and the output unit are each implemented via at least one processor.
