Claim 9:
10. An audio attack mitigation system comprising:
a processor;
a memory that stores instructions that, when executed by the processor, 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; and
determining, based upon the comparing of 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.
