Abstract: A computerized system and method may detect potentially fraudulent events where agent access credentials are used by an unauthorized party, based on calculations, comparisons, and analyses performed using recorded audio data, and execute corrective actions based on calculated results. A computerized system including a processor or a plurality of processors, a communication interface to communicate via a communication network with one or more remote computing devices, and a memory including a data store of a plurality of data items—which may, e.g., describe the remote computing devices and/or interactions involving the remote computing devices—may compare a plurality of voice signatures, which may describe calls from a plurality of remote computers, to a plurality of corresponding voice models—and, if the comparison results in a mismatch, perform a plurality of corrective actions (which may include, e.g., terminating one or more calls involving one or more remote computers).

Abstract: A text search query including one or more words may be received. An ASR index created for an audio recording may be searched over using the query to produce ASR search results including words, each word associated with a confidence score. For each of the words in the ASR search results associated with a confidence score below a threshold (and in some cases having one or more preceding words in the ASR index and one or more subsequent words in the ASR index), a phonetic representation of the audio recording may be searched for the word having the confidence score below the threshold, where it occurs in the audio recording, possibly after the one or more preceding words and in the audio recording before the one or more subsequent words, to produce phonetic search results. Search results may be returned include ASR and phonetic results.
