Claim 0:
1. A method comprising:
obtaining, by an audio attack mitigation system comprising a processor, an original digital audio signal;
sampling, by the audio attack mitigation system, the original digital audio signal to create a plurality of audio samples;
generating, by the audio attack mitigation system, a plurality of text samples from the plurality of audio samples;
comparing, by the audio attack mitigation system, the plurality of text samples;
determining, by the audio attack mitigation system, based upon the comparing of the plurality of text samples, if the plurality of text samples match;
in response to determining that the plurality of text samples match, generating, by the audio attack mitigation system, a first text output;
enhancing, by the audio attack mitigation system, the original digital audio signal, thereby creating an enhanced digital audio signal;
generating, by the audio attack mitigation system, a plurality of enhanced audio text samples from the enhanced digital audio signal;
compressing, by the audio attack mitigation system, the original digital audio signal, thereby creating a compressed digital audio signal;
generating, by the audio attack mitigation system, a plurality of compressed audio text samples from the compressed digital audio signal;
comparing, by the audio attack mitigation system, the plurality of enhanced audio text samples and the plurality of compressed audio text samples; and
determining, by the audio attack mitigation system, 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.
