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.

Claims20

Dependent claims

A system of audio verification comprising:

a processor;
and
memory comprising processor-executable instructions that when executed by the processor cause implementation of an audio generation component configured to:
identify an audio signal comprising a code for user verification;
create a second audio signal based upon one or more audio segments;
identify a pitch and a volume of the audio signal at a first time;
identify a second pitch and a second volume of the second audio signal at a second time;
determine an average pitch between the pitch of the audio signal and the second pitch of the second audio signal;
determine an average volume between the volume of the audio signal and the second volume of the second audio signal;
alter the pitch of the audio signal and the second pitch of the second audio signal to be the average pitch at a third time;
alter the volume of the audio signal and the second volume of the second audio signal to be the average volume at a fourth time;
combine the audio signal and the second audio signal to generate a verification audio signal in response to:
determining that the pitch of the audio signal at the third time and the second pitch of the second audio signal at the third time are both the average pitch so that a bot is unable to discern a difference between the pitch of the audio signal and the second pitch of the second audio signal when the audio signal and the second audio signal are combined;
and
determining that the volume of the audio signal at the fourth time and the second volume of the second audio signal at the fourth time are both the average volume so that a bot is unable to discern a difference between the volume of the audio signal and the second volume of the second audio signal when the audio signal and the second audio signal are combined;
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 verification audio signal, matching the code within the verification audio signal.

A method of audio verification comprising:

identifying an audio signal comprising a code for user verification;
creating a second audio signal based upon one or more audio segments;
identifying a speaking rate and an amplitude of the audio signal at a first time;
identifying a second speaking rate and a second amplitude of the second audio signal at a second time;
altering the speaking rate of the audio signal and the second speaking rate of the second audio signal by altering the speaking rate be more similar to the second speaking rate at the second time and altering the second speaking rate to be more similar to the speaking rate at the first time;
altering the amplitude of the audio signal and the second amplitude of the second audio signal by altering the amplitude be more similar to the second amplitude at the second time and altering the second amplitude to be more similar to the amplitude at the first time;
combining the audio signal and the second audio signal to generate a verification audio signal in response to:
determining that a bot is unable to discern a difference between the speaking rate of the audio signal and the second speaking rate of the second audio signal when the audio signal and the second audio signal are combined;
and
determining that a bot is unable to discern a difference between the amplitude of the audio signal and the second amplitude of the second audio signal when the audio signal and the second audio signal are combined;
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 verification audio signal, matching the code within the verification audio signal.
