Abstract

Methods, systems, and apparatus for monitoring a sound are described. An audio signal is obtained and the audio signal is analyzed to generate an audio signature. An object type is identified based on the audio signature and an action corresponding to the object type is identified.

Claims

1. An apparatus for monitoring and identifying a source of a sound, the apparatus comprising:

a processor;

memory to store instructions that, when executed by the processor cause the processor to perform operations comprising;

obtaining a non-verbal audio signal and analyzing the non-verbal audio signal to generate an audio signature; and

generating a search query for locating an item on an electronic commerce marketplace based on the audio signature.

2. The apparatus of claim 1, the operations further comprising identifying an object based on the audio signature, the search query corresponding to the object.

3. The apparatus of claim 2, the operations further comprising identifying a characteristic of the object based on the audio signature.

4. The apparatus of claim 1, the operations further comprising storing the audio signature in a signature library and generating an index according to an object type.

5. The apparatus of claim 2, the operations further comprising storing the audio signature in a signature library and generating an index according to the identity of the object or a characteristic of the object.

6. The apparatus of claim 1, the operations further comprising identifying an object type by comparing the audio signature to one or more signatures in a library of signatures.

7. The apparatus of claim 1, the operations further comprising executing a search using the search query.

8. The apparatus of claim 1, the operations further comprising isolating one or more sound components in the audio signal.

9. The apparatus of claim 1, wherein the analyzing the audio signal is performed periodically, at a prescheduled time, in response to a reception of a measurement request, and in response to a substantial change in the audio signal.

10. The apparatus of claim 2, wherein the analyzing operation analyzes the sound emitted by the object to determine a behavior of a user.

11. The apparatus of claim 1, wherein the analyzing operation is based on characteristics of an audio waveform, including a frequency range, a tempo, acoustic resonances, or a power in each of a plurality of frequency ranges.

12. A method for monitoring and identifying a source of a sound, the method comprising:

obtaining a non-verbal audio signal and analyzing the non-verbal audio signal to generate an audio signature; and

generating a search query for locating an item on an electronic commerce marketplace based on the audio signature.

13. The method of claim 12, further comprising identifying an object based on the audio signature, the search query corresponding to the object.

14. The method of claim 13, further comprising identifying a characteristic of the object based on the audio signature.

15. The method of claim 12, further comprising storing the audio signature in a signature library and generating an index according to an object type.

16. The method of claim 14, further comprising storing the audio signature in a signature library and generating an index according to the identity of the object or the characteristic of the object.

17. The method of claim 12, further comprising identifying an object type by comparing the audio signature to one or more signatures in a library of signatures.

18. The method of claim 12, further comprising executing a search using the search query.

19. The method of claim 12, wherein the analyzing operation is based on characteristics of an audio waveform, including a frequency range, a tempo, acoustic resonances, or a power in each of a plurality of frequency ranges.

20. A non-transitory computer-readable medium embodying instructions that, when executed by a processor of a machine, cause the machine to perform operations comprising:

obtaining a non-verbal audio signal and analyzing the non-verbal audio signal to generate an audio signature; and

generating a search query for locating an item on an electronic commerce marketplace based on the audio signature.
