Abstract

One or more techniques and/or systems are provided for audio verification. An audio signal, comprising a code for user verification, may be identified. A second audio signal is created comprising speech. The audio signal and the second audio signal may be altered to comprise a same or similar volume, pitch, amplitude, and/or speech rate. The audio signal and the second audio signal may be combined to generate a verification audio signal. The verification audio signal may be presented to a user for the user verification. Verification may be performed to determine whether the user has access to content or a service based upon user input, obtained in response to the user verification audio signal, matching the code within the user verification audio signal. In an example, the user verification may comprise verifying that the user is human.

First claim

What is claimed is:

1 . A system of audio verification comprising:
an audio generation component configured to:
identify an audio signal comprising a code for user verification;
create a second audio signal comprising speech;
identify a pitch and a volume of the audio signal;
identify a second pitch and a second volume of the second audio signal;
alter at least one of the pitch of the audio signal or the second pitch of the second audio signal until the pitch and the second pitch are within a threshold pitch similarity;
alter at least one of the volume of the audio signal or the second volume of the second audio signal until the volume and the second volume are within a threshold volume similarity;
combine the audio signal and the second audio signal to generate a verification audio signal;
present the verification audio signal to a user for the user verification, the user verification comprising verifying that the user is human; and
verify whether the user has access to content or a service based upon user input, obtained in response to the user verification audio signal, matching the code within the user verification audio signal.

2 . The system of claim 1 , the audio generation component configured to:
identify a speaking rate of the audio signal; and identify a second speaking rate of the second audio signal.

3 . The system of claim 2 , the audio generation component configured to:
alter at least one of the speaking rate of the audio signal or the second speaking rate of the second audio signal until the speaking rate and the second speaking rate are within a threshold speaking rate similarity.

4 . The system of claim 1 , the audio generation component configured to:
identify an amplitude of the audio signal; and identify a second amplitude of the second audio signal.

5 . The system of claim 4 , the audio generation component configured to:
alter at least one of the amplitude of the audio signal or the second amplitude of the second audio signal until the amplitude and the second amplitude are within a threshold amplitude similarity.

6 . The system of claim 1 , the audio generation component configured to:
create the second audio signal utilizing a first audio segment and a second audio segment.

7 . The system of claim 6 , the audio generation component configured to at least one of:
extract at least one of the first audio segment or the second audio segment in real-time from an on-going audio stream; extract at least one of the first audio segment or the second audio segment from an audio content database; or generate at least one of the first audio segment or the second audio segment utilizing a random speech generator.

8 . The system of claim 6 , the audio generation component configured to:
randomly extract one or more portions from at least one of the first audio segment or the second audio segment; and randomly stitch the one or more portions together to create the second audio signal.

9 . The system of claim 6 , the audio generation component configured to:
randomly extract one or more portions from at least one of the first audio segment or the second audio segment; randomly layer the one or more portions over each other to create a layered segment and a second layered segment; and stitch the layered segment and the second layered segment together to create the second audio signal.

10 . The system of claim 6 , the audio generation component configured to:
randomly extract one or more portions from at least one of the first audio segment or the second audio segment; randomly stitch the one or more portions together to create an initial second audio signal; and reverse the initial second audio signal to create the second audio signal.

11 . The system of claim 1 , the audio generation component configured to:
create the audio signal to comprise the code as a whisper.

12 . The system of claim 1 , the audio generation component configured to:
provide the user with an option to enter the user input audibly; responsive to the user entering the user input audibly, identify acoustic features that are indicative of a human voice; and responsive to the acoustic features indicating that the user input was spoken by the human voice, verify the user access to the content or the service.

13 . The system of claim 1 , the audio generation component configured to:
provide the user an option to enter the user input audibly; responsive to the user entering the user input audibly, identify acoustic features that are indicative of a human voice; and responsive to the acoustic features indicating the user input was not spoken by a human voice, deny the user access to the content or the service.

14 . A method of audio verification comprising:
identifying an audio signal comprising a code for user verification; creating a second audio signal comprising speech; identifying a speaking rate and an amplitude of the audio signal; identifying a second speaking rate and a second amplitude of the second audio signal; altering at least one of the speaking rate of the audio signal or the second speaking rate of the second audio signal until the speaking rate and the second speaking rate are within a threshold speaking rate similarity. altering at least one of the amplitude of the audio signal or the second amplitude of the second audio signal until the amplitude and the second amplitude are within a threshold amplitude similarity; combining the audio signal and the second audio signal to generate a verification audio signal; presenting the verification audio signal to a user for the user verification, the user verification comprising verifying that the user is human; and verifying whether the user has access to content or a service based upon user input, obtained in response to the user verification audio signal, matching the code within the user verification audio signal.

15 . The method of claim 14 , comprising:
identifying a pitch of the audio signal; identifying a second pitch of the second audio signal; and altering at least one of the pitch of the audio signal or the second pitch of the second audio signal until the pitch and the second pitch are within a threshold pitch similarity.

16 . The method of claim 14 , comprising:
identifying a volume of the audio signal; identifying an second volume of the second audio signal; and altering at least one of the volume of the audio signal or the second volume of the second audio signal until the volume and the second volume are within a threshold volume similarity;

17 . The method of claim 14 , comprising:
creating the second audio signal utilizing a first audio segment and a second audio segment.

18 . The method of claim 17 , comprising at least one of:
extracting at least one of the first audio segment or the second audio segment in real-time from an on-going audio stream; extracting at least one of the first audio segment or the second audio segment from an audio content database; or generating at least one of the first audio segment or the second audio segment utilizing a random speech generator.

19 . A system of audio verification comprising:
