Claim 18:
19. A computer-readable storage medium having instructions stored thereon that, when executed by a processor of an audio attack mitigation system, cause the processor to perform operations comprising:
obtaining an original digital audio signal;
sampling the original digital audio signal to create a plurality of audio samples;
generating a plurality of text samples from the plurality of audio samples;
comparing the plurality of text samples;
determining, based upon comparing the plurality of text samples, if the plurality of text samples match;
in response to determining that the plurality of text samples match, generating a first text output;
enhancing the original digital audio signal, thereby creating an enhanced digital audio signal;
generating a plurality of enhanced audio text samples from the enhanced digital audio signal;
compressing the original digital audio signal, thereby creating a compressed digital audio signal;
generating a plurality of compressed audio text samples from the compressed digital audio signal;
comparing the plurality of enhanced audio text samples and the plurality of compressed audio text samples;
determining, based upon comparing the plurality of enhanced audio text samples and the plurality of compressed audio text samples, if the plurality of enhanced audio text samples and the plurality of compressed audio text samples match;
in response to determining that the plurality of enhanced audio text samples and the plurality of compressed audio text samples match, generating a second text output;
comparing the first text output and the second text output; and
determining, based upon comparing the first text output and the second text output, if the first text output and the second text output match.
