1. A method for enhancing the analysis of at least one test word extracted from a test audio source, the test audio source captured within an environment and having an acoustic environment, the method comprising: a first receiving step for receiving at least one training word extracted from a training audio source; a first feature extraction step for extracting at least one first feature from each of the at least one training word, from the environment, or from the acoustic environment; a second receiving step for receiving an indication whether the at least one training word appears in the training audio source; and a model generation step for generating a model using the at least one training word and the at least one first feature, and the indication; a third receiving step for receiving at least one test word extracted from the test audio source; a second feature extraction step for extracting at least one second feature from the test audio source, from the environment or form the acoustic environment; and a classification step for applying the word training model on the test word and the at least one second feature, thus obtaining a confidence score for the at least one test word.
