Abstract

Event audio data that is based on verbal utterances associated with a pharmaceutical event associated with a patient may be received. Medical history information associated with the patient may be obtained, based on information included in a medical history repository. At least one text string that matches at least one interpretation of the event audio data may be obtained, based on information included in a pharmaceutical speech repository, information included in a speech accent repository, and a drug matching function, the at least one text string being associated with a pharmaceutical drug. One or more adverse drug event (ADE) alerts may be determined based on matching the at least one text string and medical history attributes associated with the at least one patient with ADE attributes obtained from an ADE repository. An ADE alert report may be generated, based on the determined one or more ADE alerts.
