1. 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;

    extract one or more audio segments in real-time from an on-going audio stream;

    create a second audio signal comprising speech based upon the one or more audio segments extracted in real-time from the on-going audio stream;

    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, wherein the pitch of the audio signal and the second pitch of the second audio signal are not within a threshold pitch similarity, and wherein the volume of the audio signal and the second volume of the second audio signal are not within a threshold volume similarity;

    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.
